  Just a thought but if you are limited by pixels maybe you can make pixel
represent a subset of data. Then if you can use that subset to test for
outliers at certain deviations you color it differently then a red dot needs
further review yellow dots are not that bad and blue dots are
inconsequential. (hot - cold colors). Each dot would represent a plotable
set of data.

  Definitely will do Doug. Its going to test my flex skills, but I hope to
have done it by the end of next week. It is complicated in that we have a
dashboard that allows the users to see many graphs for all the different
sensors, contact inputs and actuators at the same time - and move them in to
display groups (each display group has its own tab). I am taking the
approach that these "display group" graphs will all be displayed for the
last 24 hours or the last hour (switchable by the user). Then if the user
wants to do further analysis he/she can select the graph to analyse it
further and we will do that in a full size window. That is where we will
apply what is discussed below.

  Graphing actuators and contact inputs is also interesting as they only
have three values - Nan, 0 and 1. I will used a stepped line for those, but
will still need to be massaging data depending on the sample size required
to fit the data into the available x-axis pixels. In this case the client
does not want the sampling to miss any state change activity. Obviously we
cant average the sample data, so for this I am thinking I will plot the
sample entry point and exit point. Then, in another series I will also plot
the number of state changes in the sample. Then the user can slice using the
slider to look at parts of the graph in more detail and thus be able to see
exactly what the activity was.

  Thanks!

  Hey Mark, 

  This might be out of the question due to client restrictions, but I'd be
very interested in seeing a screenshot of the solution you come up with
(even if you have to use some fake data to show us). It's an interesting
data visualization problem and I think it would benefit many people here (or
maybe just me) to see how you decided to solve it. So if after you figure
out a workable solution you can share what you did and how well it worked,
I'd be interested.

  Thanks Doug,

  Yes I have been thinking (the last hour) of using such a representation or
alternatively of plotting a graph of floating columns, with each column
starting at min and ending at max, combined with a line graph in a different
colour showing the averages. BUT (and this is a big but) the client said he
was not interested in min and max, but rather exceptional values. Although I
have to take his requirements with a grain of salt sometimes it does pay to
listen to him - he is the client! :)

  The exceptions may be a single solitary value or a series of values. So,
if I were to grab the points that within each sample are 1 or 2 std
deviations outside the normal then I wont always have these points - so they
may just be the odd value. Hence using floating columns to display these
seems to make sense.

  What if you aggregate your data by some amount (say the maximum resolution
you can display on the x-axis), and then for each data point you plot the
min, max, and average, kind of like the HLOCChart that's used to show stock
data. That would let you see the average trend as well as identify any peaks
or valleys that were out of the ordinary. So then the task involves being
able to efficiently take 500,000 points and turn it into 2,000 aggregated
points with min/max/avg.

  Or even just do 3 completely separate line series for the min, max

this.setStyle("fillAlphas",[this.getStyle("fillAlphas")[0],

I have an AdvancedDataGrid using the default renderer. When I edit a cell

I have 2 mirrored environments. One on my laptop running Adobe CF8 and
one at the University running Blue Dragon 7. I have the same  CFCs set
to remote, the same database stucture, and the same  on
both. I am just switching the wsdl location between the 2 and I am
getting COMPLETELY diffferent responses. The only difference is the
actual Servers.

When I return a query via web service with Adobe and render it out with
Alert.show(ObjectUtil.toString(e.result),'Result');, I get this:

(mx.collections::ArrayCollection)#0
  filterFunction = (null)
  length = 1
  list = (mx.collections::ArrayList)#1
length = 1
source = (Array)#2
  [0] (Object)#3
DEPARTMENT = "PRMC"

uid = "12003FBD-127E-EEEB-4E25-22A5E6599FF8"

With Blue Dragon I get this:

  length = 8

  uid = "2A52253B-DDF8-716E-0A74-22A4F7A38643"
sort = (null)
source = (Array)#6

I then added
Alert.show(ObjectUtil.toString(e.result.list.source),'source'); and got
this with Adobe:

(Array)#0
  [0] (Object)#1
DEPARTMENT = "PRMC"
FIRSTNAME = "Wally"
ISACTIVE = 1
LASTNAME = "Kolcz"
PASSWORD = "2113"
POSITION = "Senior ColdFusion Architect"
ROLE = "admin"
UNIQNAME = "wkolcz"

And this with Blue Dragon:

TypeError: Error #1010: A term is undefined and has no properties.

Anyone know a work around to get the same results? I was able to get my
'uniqname' with Adobe by using userData.getItemArt(0).UNIQNAME but it
fails in BD.

Thanks for ANY help in this Blue Disaster.

RE: [flexcoders] Re: Setting data from web service to ArrayCollection.

2009-01-29 Thread Tracy Spratt

Or, if you are committed to WebService:

ResultFormat = "object" causes Flex to convert the WebService SOAP xml
into a tree of dynamic objects.  This has many drawbacks and few
benefits.

Set resultFormat="e4x" and either use the XML directly, or wrap the
desired XMLList in an XMLListCollection, or loop over the XMLList and
build an ArrayCollection of strongly typed value objects.

If you go this way, be sure to inspect the result xml.  SOAP adds
several layers you will need to navigat through to get to your real
data.

I think you said that your resultFormat was set to "Object". That 
being the case, Flex isn't going to take that one Object and make an 
ArrayCollection out of it.

Why are you bothering with the extra hassle of WebServices anyway? Why 
not use Remoting?

2009-01-29 Thread Tracy Spratt

"...repeater is rarely the sollution..."  

 

I disagree intensely.  It depends entirely on the problem.  Repeater
should not be used to replace a List-based control for a large number of
items.

 

But it should always be considered when you start using addChild()
statements driven by some data structure.

 

And it can replace List for a limited number of items, or if you use a
paged navigation instead of scroll.

 

Repeater has gotten an undeserved "bad rap" from folks using it
improperly.

Yes sorry - I was scant with the details because I know people don't
read long posts.

I'm just using a standard array for the dp rather than an
ArrayCollection and I am overwriting the array each time. Eventually I
think that each bundle may have completely different items (they are
actually funds - this is a financial app) , but in my test data I just
have 4 funds. It was a question out of curiosity more than anything
else. I was trying to knock something together quickly as this is just a
prototype screen.

at the moment (in the test data) I have the same 4 funds for each
bundle. From the UIDs I get, it looks like the renderers get recycled
and always in the same order - ie the renderer that was last used to
display item4 is then used to display item1 the next time around. If you
knew your List would never scroll, and you had the same four items, I
wondered if there was a way to turn off recycling, or at least get the
renderer in position1 to be in position1 again after a refresh.


n.b. Currently I send in the old percent & new percent, the override set
data and determine the state using those values, so the uissue is
solved, but curious to know if there is a way to get the same renderers

I looked at a similar example from Alex Harui - he compares a DataGrid's

If they match, he knows he has the same item and changes that value.

I have implemented IDropInListItemRenderer (so I have access to the UID)

RE: [flexcoders] LCDS : Managed associations - creating new Items

2009-01-29 Thread Jeff Vroom

Hi Bart,

Sorry for the delay in my reply.   Unfortunately that "undefined" error is a 
player bug which is effectively hiding from us the real source of the error.   
The line number in the stack trace is a finally clause... the player is 
misreporting the source of the actual error.

The CommitResponder class is going to be calling your responder functions so if 
one of them gets a runtime time error, it would end up showing that stack 
trace. In the past, to find particularly nasty errors like this I've had to 
rewrite the code to eliminate the finally clause so we can find the actual 
error.

If you use the  we print messages before and after calling the 
user result handlers so that might help track down where the error is 
occurring.   I'd probably stop in the userCreated function and step through it 
in the debugger first just to be sure it completes successfully.

Just adding an item to a managed collection will implicitly queue up a "create" 
for the child item.If you call "createItem" it also adds a new client 
reference just for that specific item.   So usually you want to avoid calling 
createItem unless that item lives all by itself.

I have a managed collection of Companies. Eeach company contains a list
of employees.
The Company-object and Employee-object are Managed objects, tagged with
the [Managed] metadata tag. They each have
an associated destination on the server (configured in the
data-management-config.xml). There exists a one-to-many managed
association between
these two objects.

When I add a new Employee to the managed arraycollection "companies"
like this :

Employee newEmployee = new Employee("John Smith", "Engineer");
companies.addItem(newEployee);
companyDS.commit();

Should this result in a createItem() in the EmployeeAssembler ?
Or should I explicitly call employeeDS.createItem(newEployee); ?

Thanks for your help..

[flexcoders] How to cancel HTTPRequest?

2009-01-29 Thread Dmitri Girski

Hi everybody,

How can I cancel the http request? Is there a way to close the
underlying socket?
I've got a situation when first HTTP request is in progress
(waiting/receiving the results), and I have to fetch the data again,
as I know that the dataset I am expecting to get is already obsolete. 

I tried to do this:

requst.cancel();
request.disconnect();
request = new HTTPService() 

But looking at the server logs I can see that connection is still
there and backend performs everything it has to and closes the
connection only when all data is sent. (Apache is at the backend) 

Any comments or help is appreciated!

Thanks!

Cheers,
Dmitri.

RE: [flexcoders] Charting 1 minute data over 1 year

Definitely will do Doug. Its going to test my flex skills, but I hope to have 
done it by the end of next week. It is complicated in that we have a dashboard 
that allows the users to see many graphs for all the different sensors, contact 
inputs and actuators at the same time - and move them in to display groups 
(each display group has its own tab). I am taking the approach that these 
"display group" graphs will all be displayed for the last 24 hours or the last 
hour (switchable by the user). Then if the user wants to do further analysis 
he/she can select the graph to analyse it further and we will do that in a full 
size window. That is where we will apply what is discussed below.

Graphing actuators and contact inputs is also interesting as they only have 
three values - Nan, 0 and 1. I will used a stepped line for those, but will 
still need to be massaging data depending on the sample size required to fit 
the data into the available x-axis pixels. In this case the client does not 
want the sampling to miss any state change activity. Obviously we cant average 
the sample data, so for this I am thinking I will plot the sample entry point 
and exit point. Then, in another series I will also plot the number of state 
changes in the sample. Then the user can slice using the slider to look at 
parts of the graph in more detail and thus be able to see exactly what the 
activity was.

Thanks!

  Hey Mark, 

  This might be out of the question due to client restrictions, but I'd be very 
interested in seeing a screenshot of the solution you come up with (even if you 
have to use some fake data to show us). It's an interesting data visualization 
problem and I think it would benefit many people here (or maybe just me) to see

  What if you aggregate your data by some amount (say the maximum 
resolution you can display on the x-axis), and then for each data point you 
plot the min, max, and average, kind of like the HLOCChart that's used to show 
stock data. That would let you see the average trend as well as identify any 
peaks or valleys that were out of the ordinary. So then the task involves being 
able to efficiently take 500,000 points and turn it into 2,000 aggregated 
points with min/max/avg.

  Or even just do 3 completely separate line series for the min, max, and 
avg. There's only so much information you can show in a single horizontal 
pixel, so there's simply no way to show all the data. But showing min/max/avg 
might get you the info you need.

RE: [flexcoders] Charting 1 minute data over 1 year

I like the idea of the separate series for the outlying points.

With respect to the main graph showing raw data ...I am not sure that would be
acceptable to the client. Depending on the range selected by the slider the
main graph would still be limited by available x-axis pixels in terms of what
it can display. At one extreme the user could user the slider to select the
whole graph - that dataset is 500,000 points. We could limit the slider to the
detail that can be displayed in the main graph. But that means that only a
small slice can be viewed at any one time, and the added user problem of having
to move two sliders to keep the slice small.

I think if we went this way then when the slider is resposition I would need to
look at the data population size for that and base on available x-axis pixels
produce a new dataset to display the top graph. But I believe this would make
the slider, slow and difficult to use, unless I allowed the sliders to be
positioned and then the user clicked some button to generate the new graph.

Hi Maciek,
 
Thanks for your response. 
 
Yes I have seen that example and I liked it. We still need to contend,
though, with having 500,000 values to plot for the full graph. Using
standard graphing that takes for ever to plot - in fact I could not get
it to plot. 2000 values seems to the maximum number of points that can
be plotted, or to be exact the number of pixels available on x-axis. So
how can I take 500,000 points and :
 
1. Producre a graph that as closely as possible retains its shape?
2. Shows exceptional values
 
If I were to massage the 500,000 points by taking sample of 250 points
and averaging them, then I can miss important detail. I could use a
vertical column graph with floating columns, where I plotted the line
starting at min and ending at max for the plot point.
 
Furthermore as the user used the slider to look at a smaller portion of
the graph I would still want to plot at maximum pixel detail. That is if
the user uses the slider to look at 1 month then that would allow me to
plot points where each point was calculated from a smaller sample size.
 
Cheers
Mark

Hi,

I am trying to work out how best to produce a chart which allows
a user
to
make sense of data logged every minute for up to 12 months (ie
524160
values). To complicate matters the graphs are are presented on a
dashboard
where the user can display many graphs at once - so we are not
just
displaying the one graph and the size of the graph will change
depending
on
how many graphs are being displayed in the dashboard window.

We are logging sensor data (temperature, current, vibration,
humidity,
wind
speed etc). Client does not like a month, week, day, hour,
minute drill
down
scenario - I tried that and it was rejected. He wants a line
graph, but
where we do have to average data would like to some idea of max
and mins
-
maybe that can be done in point comment. Trouble is if we chart
so many
points then there are too many points for the mouse click to
discern.

Essentially the client would like to see the data always at
maximum
detail
no matter what period is being looked at. I have read this

http://www.cynergysystems.com/blogs/page/andrewtrice?entry=visualizing_large
_data_sets, and am thinking that I will need to proceed in kind
and to
use
an Image object and set BitmapData pixels directly - depending
on how I
decide to reimplement this thing. Of course I am limited by the
number
of
pixels available along the x-axis for a given chart size.

This is complicated as the client would like to zoom on the
graph and
also
look at time slices. The client would also like to be able to
see
exceptions
clearly on the graph - for example if there was a vibration
spike. Also
sometimes the sensor might not be operational so we need to see
those
breaks
in the graph when no data was captured.

Hi S,

That's a toughie...I haven't tried to selectively deny a drop depending on

I don't know of any methods that will reject the drag-drop other than the 
stopPropagation and stopImmediatePropagation methods.  You might try looking 
the DRAG_OVER event to see if you can selectively showDropFeedback and 
hideDropFeedback depending on what rows you are over and then in your listener, 
if it's dropped where its not supposed to be cancel the op. Another idea would 
be if you know which row's you don't want drop enabled on, see if you can 
manipulate the drop properties of those row to deny the drop??

Not really sure what else to do herebut am interested to know if you 
find out how!

Hi Adrian,

Thanks for the response. So I didn't know about the hideDropFeedback
method on the ListBase class. That helps a bit but the problem I'm
encountering now, is that when I start dragging, it denies it at
first, but once it passed over a row that it's able to drop, it
becomes droppable over all the rows. It looks like the
DragManager.acceptDragDrop() toggles on and won't turn back off even
if I hide the dragDropFeedback. Is there a method like
DragManager.rejectDragDrop() so that when I'm dragging a row over all
the rows, that it will reject certain rows, but accepts others?

Thanks

Re: [flexcoders] flex date and timezone

2009-01-29 Thread Nate Beck

Hey Gordon, you're on the right track.  Everything in the database is stored
as UTC.  However, here are two instances I ran into in the past where
timezone conversion needed to happen.

1) A scheduler in Seattle (PT) needs to create an event in a location that
is in a different timezone, let's say New Jersey (ET).  In this Flex
application, the scheduler uses a calendar control to create events
scheduled in "Activity local time".  So let's say the scheduler wants to
create an event for 3pm.

The problem with the Date class is that if he sets "3pm" it's in Pacific
time, when it is converted to UTC, it's going to be off by 3 hours from the
desired time.  The only way to make the software to work correctly would be
either add timezone knowledge to Flex, or do the timezone conversion on the
server.

The big problem with doing the conversion on the server, means that in your
request to the server you need to include the client local timezone offset
as well as the offset that the activity is occuring in.

2) A manager is tracking events in multiple locations in a Dashboard
application.  He wants to see the times in Activity local time.  Much like
looking at those screens at the airport.  Depature time is the depature
airport time, and arrival time is in arrival airport time.

The solution we ended up implementing was to monkey patch SchemaMarshaller
to accept a new type of class, DateTime.  DateTime is a proxy for Date,
which has an added method setTimezone.  Then we have a lazy loaded
dictionary which caches different timezone's information on an as needed
basis.
So this brings me back to my original statement... timezones are a hard
thing to implement.

Hope that makes sense.

Cheers,
Nate

Re: [flexcoders] Re: DataGrid Drop Deny based on dropIndex

2009-01-29 Thread Adrian Williams

Hi S,

   That's a toughie...I haven't tried to selectively deny a drop 
depending on an index...

   I don't know of any methods that will reject the drag-drop other 
than the stopPropagation and stopImmediatePropagation methods.  You 
might try looking the DRAG_OVER event to see if you can selectively 
showDropFeedback and hideDropFeedback depending on what rows you are 
over and then in your listener, if it's dropped where its not supposed 
to be cancel the op. Another idea would be if you know which row's you 
don't want drop enabled on, see if you can manipulate the drop 
properties of those row to deny the drop??

   Not really sure what else to do herebut am interested to know if 
you find out how!

Best,
Adrian

becomes droppable over all the rows. It looks like the
DragManager.acceptDragDrop() toggles on and won't turn back off even
if I hide the dragDropFeedback. Is there a method like
DragManager.rejectDragDrop() so that when I'm dragging a row over all
the rows, that it will reject certain rows, but accepts others?

[flexcoders] dynamic context menu problem

2009-01-29 Thread Michael Pelz-Sherman

I'm struggling to find an elegant solution to this problem:

I have a Flex app that has a dynamic context (right-click) menu.

The menu contains different items depending on whether various objects are 
selected.

Ideally, I'd like to re-generate the menu options right when the user 
right-clicks, but I haven't found a reasonable way to do this.

So instead I'm re-generating the menus every time the user (left) clicks, which 
is kind of expensive and is having unwanted side-effects.

Unfortunately, MouseEvent.RIGHT_CLICK is AIR-only.

Any suggestions would be most appreciated!

[flexcoders] Re: Call method on nested SWF

There is one other problem with that example. The SWFLoader has a 

creationComplete="initNestedAppProps();"

If you use that then loadedSM will be null. It should be

complete="initNestedAppProps();"

Re: [flexcoders] Common base class for components

2009-01-29 Thread Jules Suggate

Is it possible for an MXML file to implement an interface? Sounds intriguing
... but won't resolve my issue unfortunately. It's the implementation code
that I want them to share.

I have developers on my team who are less than keen on having to duplicate
repetitive code around the place -- they want to focus on cool effects,
state transitions and backend integration :-)

And I don't want repeated code everywhere in the app since if we want to
change something, there'll eventullay be hundreds of places where we have to
do so if the code is copy+pasted around the place...

Hi -

I've been using Flex to write some data visualizations and am in the
process of writing an admin tool to customize the look n' feel of each
visualization. My admin app uses SWFLoader to load the individual
visualizations - a really nice thing to be able to do (load a full app
inside another app). I need to call the accessors to the look n'
feel properties inside the nested SWF's from the main app so that I
can do real time changes that will upon completion be written to the
actual config files that the visualization tools use.

So - all of the Adobe docs and blog posts on this topic seem to point
to the same tutorial on calling methods and properties on nested swf's:

http://livedocs.adobe.com/flex/3/html/help.html?content=controls_15.html

I can't seem to get this to run and I can't figure out what is
happening here:

// Write to the varOne variable in the loaded application
// using the setVarOne() method of the loaded application.
public function updateNestedVarOne():void {
FlexApp(loadedSM.application).setVarOne("Updated
varOne!");
}

I don't understand the "FlexApp()" casting or whatever that is -
FlexApp is the name of the loaded app - is this what this refers to?
My sample apps always bombs out on that line as an undefined method

Thanks!

Strings are interned by the AVM in both the Player and AIR. 

So if you have highly sensitive character data and you're worried about memory 
scanning, you'd want to use an array of characters, and scramble the contents 
manually after you've used the value in order to render it illegible until the 
array is GCed. There's no perfect solution here, but this reduces the attack 
surface.

Again, not a concern for most apps.

Sorry - typo. That should have been: You _don't_ need to worry about encryption 
in this scenario. If you're worried about encrypting bytes sent over 
LocalConnections (just a block of shared memory on your local system), I'd 
assume you'd also need to be worried about those same values in the memory 
space used by the Player or AIR instances that are communicating via 
LocalConnections. Given the GC'ed nature of ActionScript, you don't have direct 
control over how long variables will stick around. So if there's a rogue 
process running locally that can scan and read anything in system memory, the 
values in Player/AIR memory space are just as vulnerable as values in the 
shared memory block used for LocalConnections. If that's the case, then you 
have bigger issues to worry about than encrypting what you're exchanging via 
LocalConnection, like getting good anti-virus software installed or something :)

There's no network involved. More details here:

It would seem that there is a network connection being used, but I
have not been able to find out for sure.

The localconnection allows different versions of the Flash player to
communicate via AMF0. This leads me to believe that the network is
being used as opposed to a shared memory model. It would be nice to
know for sure, but it is now a moot point for my applications.

I have taken the time to implement RSA encryption in my communication
classes so that the two AIR applications exchange public keys at the
time of the first Send command.

Once the handshaking of public keys has been completed, the future
messages are encrypted and pushed out through the use of the Send method. 

The receiving app then decrypts the message using its private keys. I
am storing the keys in the encrypted local store. That brings up the
question of just how secure is the encrypted local store?

[flexcoders] Advanced Formatting

2009-01-29 Thread Dharmendra Chauhan

Hi All,
 This time I am struggling with formatting as I am migrating Dot
Net application to flex.Standard flex library does not support
advanced formatting.
Here is type of formatting which I want to implement in Flex

1) 0 (Zero placeholder):

If the value being formatted has a digit in the position where the '0'
appears in the format string, then that digit is copied to the result
string; otherwise, a '0' appears in the result string. The position of
the leftmost '0' before the decimal point and the rightmost '0' after
the decimal point determines the range of digits that are always
present in the result string.

The "00" specifier causes the value to be rounded to the nearest digit
preceding the decimal, where rounding away from zero is always used.
For example, formatting 34.5 with "00" would result in the value 35.
   
2) #(Digit placeholder):
If the value being formatted has a digit in the position where the
'#' appears in the format string, then that digit is copied to the
result string. Otherwise, nothing is stored in that position in the
result string.

Note that this specifier never displays the '0' character if it is not
a significant digit, even if '0' is the only digit in the string. It
will display the '0' character if it is a significant digit in the
number being displayed.

The "##" format string causes the value to be rounded to the nearest
digit preceding the decimal, where rounding away from zero is always
used. For example, formatting 34.5 with "##" would result in the value 35.


Please suggest me ways to provide advanced formatting in flex.
Any help would be highly appreciated

Dharmendra

[flexcoders] Sailorsea21 - Animated pie chart still displays old data when updated???

2009-01-29 Thread sailorsea21

Hi everyone, I created an animated pie chart that is divided into 3 
segments.


 
  
   

   
 

  

The pie animates perfectly but when new data comes in, if the new 
data has only data for 2 out of the 3 segments, it will animate 
correctly and display the sections correctly but the old data from 
the 3rd section remains as if it's cached somehow. If I minimize IE 
and then restore it, the old data disappears as if the page 
refreshes... Is there a way to automatically refresh the page still 
animating the pie charts. If I remove the animation I do not have 
this problem.

Thanks.

Just a theory... but you might be able to use ExternalInterface to call the
same methods within user.js, and pass the content.  Since you're already got
it working within Javascript.

I wish I knew more about FlexPrintJob.

[flexcoders] Silent Print from Flex on Kiosk

2009-01-29 Thread Jeremi Bergman

I have a flex app that I need to print an image.  I have Firefox Setup
running the app.

in user.js for FF i have:
user_pref(âprint.always_print_silentâ,true);
user_pref(âprint.show_print_progressâ,false);

This works perfectly when using firefox's print functionality on any
standard site.  It prints directly to the default printer without any
user interaction.

Within my App I have:

public static function 
printCoupon(obj:UIComponent):void {
// Create an instance of the FlexPrintJob class.
var printJob:FlexPrintJob = new FlexPrintJob();

// Start the print job.
if (printJob.start() != true) return;

// Add the object to print. Do not scale it.
printJob.addObject(obj, FlexPrintJobScaleType.NONE);

// Send the job to the printer.
printJob.send();
}

The UIComponent passed in is an Image.

It prints the image, but it prompts me with the print diologe box.

Any thoughts?  Thanks.

[flexcoders] using webcam to broadcast through a video object, how to stop broadcasting?

2009-01-29 Thread blc187

I have a video object that I am attaching a webcam to.
Video works, camera broadcasts fine.

Problem is, when I close the window with the video in it, I want to be 
able to shut the camera off.  Right now the light on the camera is 
still on to indicate it is still broadcasting.

Documentation says to pass a null object to video.attachCamera(null) 
to drop the connection to the camera.  I am doing the following:

_videoCamera.attachCamera(null);
_videoCamera.attachNetStream(null);
_videoCamera.clear();
_videoCamera = null;

Yet my video camera still looks like it's on and broadcasting.
Is there any other way to shut the camera itself off?

[flexcoders] Re: Flex or JavaFX?

2009-01-29 Thread mitchgrrt

I would avoid Java FX on the client side like the plague.  It's a 
repackaging of the 15-year-old Java Applet technology which has a lot 
of problems.  Java Swing is a nice API for building GUIs, but Java 
Applets and especially the Java Plug-in in browsers have a lot of 
problems that I would not want to experience again.  (I developed 
Applets for years before switching to Flex.)

I would recommend Flex on the client side, Java on the server side, 
and either BlazeDS or LCDS for communicating between client and 
server.  BlazeDS is free and simple, LCDS is elaborate and expensive.

[flexcoders] Datagrid bound to XMLListCollection not updating properly - ItemRenderer issue?

2009-01-29 Thread flexcoder2008

I am having trouble getting a datagrid that is bound to an
XMLListCollection to update properly.  The datagrid uses item
renderers for a couple of the columns which display a simple colored
image.  




   
 
   




This datagrid's dataProvider is set to bind to an XMLListCollection
variable which contains XML with one of the nodes being 


This datagrid is a part of a module that gets loaded into a
TabNavigator control.  When the module initializes I loop through each
row in the datagrid and check the values of the XML, and depending on
certain values, I update the content of the  node, which in
turn will change the image source property.

When the module first loads, everything works fine and the grid
displays correctly.

The problem happens when I load a different module into the
tabNavigator.  In a seperate module I do an update to this same
XMLListCollection.  (I am using the Cairngorm framework and all my
shared data is stored in the model. ) When I reload the first module,
and the initialization logic fires, as I am looping through to do the
calculations to update the  node I can see that everything is
updating in the XMLListCollection correctly.

However, when the dataGrid displays, the row that corresponds to the
updated XML in the XMLListCollection is displaying a blank row, even
though the underlying values are correct.

I believe this is a problem with the ItemRenderer not updating itself.
 How do I force it to invalidate?  I have tried doing a
dataGrid.dataProvider.refresh() and calling invalidateDisplayList()
etc. but cannot figure this one out.

One workaround I discovered is that when I reload the first module
after updating the underlying XMLListCollection, if I append a new
empty node to the XML like so:  myXML.* += Then the
updated row displays correctly!

Has anybody else out there ran into this problem?

[flexcoders] Re: RadioButtonGroup id not settable using repeater index...

2009-01-29 Thread jonathanrowny

Here's how to do it!

FIRST, in Actionscript create a function that will generate rbGroups
which is an arrayCollection of your radio button groups.

[Bindable] 
private var rbGroups:ArrayCollection;

private function createRBGroups():void{
rbGroups= new ArrayCollection();
var repeaterDP:ArrayCollection = someRepeater.dataProvider as
ArrayCollection;
var rbGroup:RadioButtonGroup;
for each(var item:Object in repeaterDP){
 rbGroup = new RadioButtonGroup();  
 rbGroups.addItem(rbGroup);
}
}


Now call that create function as the repeater starts! Now when we loop
through we can set the appropriate group. You can always refer to a
group by it's index! Since it is an array collection, binding works too!

[flexcoders] Filenames and List Class Default Item Renderer

2009-01-29 Thread Kevin

I just noticed that when I pass a filename as part of the label for a List 
component, an icon is 
automatically show as part of the default ItemRenderer. I was actually starting 
to build this 
functionality myself with a custom IR.  I can't believe I haven't noticed this 
before...

Does anyone know where this icon is being set (I looked in ListItemRenderer but 
didn't see it 
there).  I can't seem to find the code that parses the label (filename) to 
figure out which icon 
to display based on the file extension.

Thanks,

[flexcoders] ItemEditors and rowHeight

Looking through SearchCoders, it looks like this question has been asked
repeatedly, and never with a good solution, but hey, I may as well ask
again!

I have an AdvancedDataGrid using the default renderer. When I edit a
cell though, I want to show an ItemEditor that is taller than the row.
I've tried numerous combinations of events and setting height properties
to no good effect.

So while I go away and delve into the ADG code to try and work out a
solution, has anyone managed this successfully, and is willing to save
me some head scratching time?

[flexcoders] Call method on nested SWF

2009-01-29 Thread nylarch

Hi - 

I've been using Flex to write some data visualizations and am in the
process of writing an admin tool to customize the look n' feel of each
visualization.   My admin app uses SWFLoader to load the individual
visualizations - a really nice thing to be able to do (load a full app
inside another app).   I need to call the accessors to the look n'
feel properties inside the nested SWF's from the main app so that I
can do real time changes that will upon completion be written to the
actual config files that the visualization tools use.

So - all of the Adobe docs and blog posts on this topic seem to point
to the same tutorial on calling methods and properties on nested swf's: 

http://livedocs.adobe.com/flex/3/html/help.html?content=controls_15.html

I can't seem to get this to run and I can't figure out what is
happening here:

 // Write to the varOne variable in the loaded application
// using the setVarOne() method of the loaded application.
public function updateNestedVarOne():void {
FlexApp(loadedSM.application).setVarOne("Updated
varOne!");
}

I don't understand the "FlexApp()" casting or whatever that is -
FlexApp is the name of the loaded app - is this what this refers to? 
 My sample apps always bombs out on that line as an undefined method

Thanks!

Its close, you do need to have a UIComponent wrapper to add the Sprite
to, and then add the UIComponent to the application.

 

So what you had there (but make sure you actually do new UIComponent() )

I then added Alert.show(ObjectUtil.toString(e.result.list.source),'source'); 
and got this with Adobe:

(Array)#0
  [0] (Object)#1
DEPARTMENT = "PRMC"
FIRSTNAME = "Wally"
ISACTIVE = 1
LASTNAME = "Kolcz"
PASSWORD = "2113"
POSITION = "Senior ColdFusion Architect"
ROLE = "admin"
UNIQNAME = "wkolcz"

And this with Blue Dragon:

TypeError: Error #1010: A term is undefined and has no properties.

Anyone know a work around to get the same results? I was able to get my 
'uniqname' with Adobe by using userData.getItemArt(0).UNIQNAME but it fails in 
BD.

Thanks for ANY help in this Blue Disaster.

[flexcoders] Re: newbie question - call to actionscript class

I tried addChild(notes); but that threw an error (Error #1034: Type 
Coercion failed: cannot convert test::drawno...@7218ca1 to 
mx.core.IUIComponent.). I googled a bit and it seems like you have to 
make it into a UIComponent first. I tried this:

var uic:UIComponent = new UIComponent;
uic.addChild(notes);

This doesn't do anything though, so maybe my actionscript code is 
wrong. I thought notes would be a Sprite, but maybe I need to do 
something more? Here's the actionscript class:

package test
{
import assets.Note;

import flash.display.Sprite;
import flash.text.*;

public class DrawNotes extends Sprite
{
[Embed(source="HELSINKI.TTF", fontFamily="HELSINKI")]
private var embeddedFont:String;

private var note1:Note;

public function DrawNotes()
{
super();

// I've removed it as it would make the code 
too long, but this calls a function that creates a textfield with the 
music notes
createTextField(17, 
AntiAliasType.NORMAL, "&", 63, 53);

note1 = new Note();
addChild(note1);
}
}
}

Cheers,

Annelie

Re: [flexcoders] Re: newbie question - call to actionscript class

2009-01-29 Thread Paul Andrews

The usual reason for things not appearing is that the component that should 
appear hasn't been added to the display list - just using new doesn't add an 
object to the display list.

Maybe addChild(notes) will help.

[flexcoders] Re: newbie question - call to actionscript class

I should probably have commented out that bit of code, it's not the 
xml I'm having problems with now (well, I have, but I'll get to those 
questions later). I thought that by calling my actionscript class, 
var notes:DrawNotes = new DrawNotes();, that would display my hard 
coded score on screen? I was going to loop through the xml later to 
go draw every specific element but for now I'm just trying to draw 
anything. Do I need to connect that to a visual element?

[flexcoders] Re: DragDrop stops working in 3.2

Never mind, resolved.

DragProxy has a different function for selecting which object to 
dispatch drag/drop events through and they produce different results

RE: [flexcoders] newbie question - call to actionscript class

 isn't a visual component. You'll need to use the XML as a
dataprovider from something that is.

I'm brand new to Flex so I'm sure this is a very stupid question, but 
hopefully someone will be able to help.

My ultimate goal is to take an xaml file with a musical score and

to call it from my main application file. When I debug I can see that

[flexcoders] Ever seen this bug? (busy loop + custom component + '\n')

2009-01-29 Thread enriirne

I've just submitted this bug. I wonder if any busy loop user (game, 
animations) have vere seen it.

Enri

See code below to reproduce the bug

Steps to reproduce:
1. add a busy loop: enter_frame or timer with 1 ms resolution
2. inside the loop set the text property of a Label or TextArea to 
'\n'
3. outside the loop, for example in a click event, addChild of a 
custom component extending Canvas (or any other container) and 
including anything
 
 Actual Results:
 a click on the application area doesn't show anything. If resized 
(when running on flash player) the custom component appears, but the 
display is corrupted and inconsistent
 
 Expected Results:
 the custom component is added and showed
 
 Workaround (if any):
 use '\r' instead of '\n'

Comments:
This seems a race condition. If timer resolution is set to 2 ms, the 
bug appears less frequently. If set to 3 ms the bug disappears (all 
this on a recent notebook)
I've found this bug both on flash player 9 and 10, and on air 1.5
I suspect that this bug appears also using PopupManager.

[flexcoders] Re: Whipping the itemRenderers Ass

2009-01-29 Thread gmbroth

Hi,

Good timing as I think I'm trying to do a similar thing:
highlighting rows in a List via an item renderer and "highlighted"
property on the data model.  After updating the data model, I
plan to call refresh() and expect it will automatically fire the
item renderer for each visible row; the renderer will detect highlighted
rows via the data property and apply an appropriate style.  Will my
approach work or are you saying I'll need to explicitly dispatch
events?

I'm not using a custom gradient and so am not too concerned about the
bugginess you report but would love to see your general approach.
Care to share some code?  We can do it offline, if you wish:
gmbr...@hotmail.com.

Finally, I don't get the part about indexToItemRenderer.  Can't you do
everything through the data model and data binding (using refresh) without
iterating over the List itself?

Thanks, Garry

Re: [flexcoders] Common base class for components

2009-01-29 Thread Jules Suggate

Just to resume this thread, what I meant was to still use MXML and all the
Flex components, but to introduce common functionality to all our Views
(mxml files). Perhaps it's better to think of weaving this in than using
inheritance, since that would require multiple inheritance AFAICT.

I don't want anything fancy -- just a getter/setter pair:

public function get model():IViewModel
{
   // some common code
}
private var _model:IViewModel;
public function set model(value:IViewModel):void
{
   // more common code
}

To save writing out this code again and again, would I have to put this code
in an include file, and include from each View?
