[flexcoders] Re: Question on Mx:HTTP Service

[sminrana]

also you can have those flashvars in your Flex application like 

var str : String = Application.application.parameters.flashvars(name);


/***/
AC_FL_RunContent(
"src", "playerProductInstall",
"FlashVars", "PUT YOUR VAR 
HERE&MMredirectURL="+MMredirectURL+'&MMplayerType='+MMPlayerType+'&MMdoctitle='+MMdoctitle+"",
"width", "100%",
"height", "100%",
"align", "middle",
"id", "CFMTest",
"quality", "high",
"bgcolor", "#869ca7",
"name", "CFMTest",
"allowScriptAccess","sameDomain",
"type", "application/x-shockwave-flash",
"pluginspage", "http://www.adobe.com/go/getflashplayer";
);
} else if (hasRequestedVersion) {
// if we've detected an acceptable version
// embed the Flash Content SWF when all tests are passed
AC_FL_RunContent(
"src", "CFMTest",
"width", "100%",
"height", "100%",
"align", "middle",
"id", "CFMTest",
"quality", "high",
"bgcolor", "#869ca7",
"name", "CFMTest", "FlashVars", "PUT YOUR VAR HERE",
"allowScriptAccess","sameDomain",
"type", "application/x-shockwave-flash",
"pluginspage", "http://www.adobe.com/go/getflashplayer";
);
/*/


and in the html wrapper also you can assign PHP , Coldfusion var in those  (" ")

so do whatever you want you can do with var str Now!!

[flexcoders] Re: Duplicate Module Loads - applicationDomain / Shared Code Issues

[Brendan Meutzner]

Alex,

I set it up using your advice for factory.create(), so it's the latter... a new 
instance of the same module.

Yeah, I figured there must be a way to distinguish the eventlistener's 
dispatcher... I'll post my results once I figure it out.

Thanks again for the help.

RE: [flexcoders] Re: Duplicate Module Loads - applicationDomain / Shared Code Issues

[Alex Harui]

By “load module 2” did you actually load a second module or is it a second 
instance of an already loaded module and thus the WebService instance is the 
same.  Hopefully it is the latter as I wouldn’t have an explanation for the 
former.

For the latter, I believe (and I am not the expert on web-services) that every 
send() method returns an AsyncToken and you can save that away and decide 
whether to respond to the result event based on the AsyncToken referenced in 
the result event.

Alex,

That definitely did the trick.

However...

I'm using DataService calls inside the modules, and now when event listeners 
get set for result/fault/conflict events on them, they carry over to the other 
modules. So if I open module 1, load it up and make a data call, then load 
module 2, the result event on module 1 & 2 get fired. I can't exactly remove 
the event listeners on these (which would be the simplest answer) because of 
the fact that data synchronization is happening through LiveCycle DS.

I have yet to look into trying to identify the calling module which causes the 
result event to see if I can single them out and ignore other multiple 
instances (which I will do tomorrow), but thought I'd post to see if there was 
an easier solution.

Thanks very much for your original answer on this... it really helped out :-)

RE: [flexcoders] Focus on itemRenderer sub-components in a non editable list

[JérémyR]

focusManager.showFocusIndicator = true works! I add it in the overriden
setFocus function and now the focus is always shown.

I understand for wraparound and you're right, it's better for accessibility
to change focused control...

Finally, calling preventDefault wisely is the key: other items are selected!

Thanks again Alex for all your answers!

[flexcoders] Re: Duplicate Module Loads - applicationDomain / Shared Code Issues

[Brendan Meutzner]

Alex,

That definitely did the trick.


However...

I'm using DataService calls inside the modules, and now when event listeners 
get set for result/fault/conflict events on them, they carry over to the other 
modules.  So if I open module 1, load it up and make a data call, then load 
module 2, the result event on module 1 & 2 get fired.  I can't exactly remove 
the event listeners on these (which would be the simplest answer) because of 
the fact that data synchronization is happening through LiveCycle DS.

I have yet to look into trying to identify the calling module which causes the 
result event to see if I can single them out and ignore other multiple 
instances (which I will do tomorrow), but thought I'd post to see if there was 
an easier solution.

Thanks very much for your original answer on this... it really helped out :-)

RE: [flexcoders] Question on Mx:HTTP Service

[Tracy Spratt]

You can use relative paths.  But that does dictate where you put data
service.

 

I often pass urls into my Flex application through flashvars in the html
wrapper.  Among other things, it lets me switch my data services between
development, QO and production servers very easily

 

Once you have the url in Flex, you can simply assign the url to the url
property:

reportProfile.url = _sMyUrl;

reportProfile.send();

[flexcoders] AIR app loading SWF, that loads other SWFs (per loadBytes and loaderContext)

[Ikezi Kamanu]

In order to load executable swfs into my AIR application sandbox, I've
been able to use the loader's "loadBytes" method, setting the
loaderContext to one that allows byte code execution (
loaderContext.allowLoadBytesCodeExecution = true  )

This is great, and the loaded swf can execute code, but that loaded
swf in turn needs to load other secondary swfs (that can execute code
as well).   However, the allowLoadBytesCodeExecution property is only
available to AIR, so when I try  loadBytes() for the secondary swfs, I
get the exception "Loader.loadBytes() is not permitted to load content
with executable code."  , and loading the secondary swf  the regular
way (not using loadBytes) does not allow for code execution in the
secondary swf.

Any ideas?

This system's been this way for many years, but I'm completely 
re-writing it, so moving that info into a separate table with rows 
instead of columns is totally do-able.  (In fact, I came up with that 
idea after Mark's comment about the rows vs. columns.)

The only thing I don't know how to do is have a CFC loop thru the 
array to store each element in the DB.  Can you help?

[flexcoders] Re: Form with 3 Custom Components...

[Tim Hoff]

There are several techniques that you can use for this; it really
depends on what the need is and the sophistication of the application. 
Personally, I would employ a presentationModel to solve this, but using
an MVC framework and VO's can be challenging for some.  In this case,
using public properties in the components would work fine.  Respectfully
though, the assertion that using events creates a "tightly-coupled"
strategy is not correct.  Tight coupling is where components have a
direct dependency on one another.  Loose coupling avoids this by linking
the components with properties and/or events.  I do agree though, that
you wouldn't necessarily want/need to pass data around amongst
components, using custom events.  This is where the beauty of a Model
comes into play.

Here's a good article to read, that might help for this solution:

It seems to me that unless this is a system that has been in long production 
(don't laugh, y'all, I've seen some tables structured exactly this way in 
enterprise scale databases), that you would be well advised to change your 
database structure so that it _is_ rows instead of columns.

It may seem quicker and easier for now to have it all within a single record, 
but when you have to keep changing the table (and query) over and over to add 
another element to your array, you will come to regret it.  Not to mention it's 
a huge violation of good normalization practice.

Probably the best way to handle this is with two tables.  One creates a "bag" 
that all the records are in, and the other will be the records that go into the 
"bag," like so:

bag
=
bagID
bagDesc

bagElements
===
elementID
bagID
elementValue
...

All bagElements with the same bagID can be retrieved at once in a query, just 
like your one record has been in the past.  But you've gained the advantage 
that you can add or remove elements from the bag at will, and you only use the 
amount of storage space that you need for the contents of the bag, rather than 
having a cardboard box that takes up the same amount of space no matter how 
much or little is in it.

Now it becomes amazingly easy to populate your tables from the array.  That's 
one reason normalization was invented.  It's a great design pattern.

RE: [flexcoders] Duplicate Module Loads - applicationDomain / Shared Code Issues

[Alex Harui]

In theory, you simply put all shared VO’s in the main app and don’t mess with 
applicationDomains.

Also in theory, if it is the same module class there is no need to load it 
twice, you should instantiate it twice (via factory.create()) and pass it 
parameters it needs to make different backend calls.  Should take less memory 
this way, and might avoid this shared code issue.

Modules don’t work if you use “new ApplicationDomain()” as there must be shared 
interfaces between the loader and loadee, and using 
applicationDomain.currentDomain will lock the module into memory.

Subject: [flexcoders] Duplicate Module Loads - applicationDomain / Shared Code 
Issues





Hi All,

I'm having trouble wrapping my head around an issue I'm facing while loading 
the same module twice into my main application.

I've got a module which takes a few arguments to load up property data.  If I 
ask for a different set of data, the same Module class gets loaded, it just 
makes different back end calls to populate its data.  My module is located in a 
different project from my main application, so optimizing to application isn't 
an option.  However, I am generating a link-report from the main application, 
and then using load-externs on the module's compile.

1) I load up an instance of the module, and it retrieves data just fine.
2) I load up a second instance of the same module, but when the data is 
returned, I get errors relating to the fact it's trying to set my data response 
to a local VO Class which has already been instantiated from the first module 
call.


I know I've got a shared code issue going on here, but can't figure this out.  
I've tried the following:

1) Placed all re-used VO files inside main application, generated link-report, 
and referenced that link-report via load-externs on the modules compilation 
then I set applicationDomain on module load to be Application.currentDomain.

2) Placed all VO files inside module where they are actually used, and then set 
applicationDomain to a "new ApplicationDomain()" instance to try and sandbox 
their use.


Neither of these worked which is suffice to say, why this post is being 
written.


Thanks in advance for help.

Re: [flexcoders] What version of AIR is req'd to run Flex 4 Gumbo?

[Matt Chotin]

Flex 4 will ship with and support AIR 1.5.  AIR runtime includes the Flash 
Player, AIR 1.5 is including Player 10.  If you check the Gumbo Language 
Reference (I think the public version, but if not, the version that will come 
out with the beta) you'll see that we've started including information on what 
version of the runtime various APIs support, etc.
