[flexcoders] FlashVars not working

[g_vaccarezza]

this is driving me mad!
Can you guys tell me what am I doin wrong?

See I have to pass a variable to my flex app then just fill a 
textfield with that value.

I wrap the app like this:


 
etc...
 etc...



Then from within the movie I call my function ON COMPLETE

private function initApp():void{
requestText.text = theText;
}

I took this from the livedocs but nothing seems to work...
Am I writing something wrong? sintax error or what?
this shouldn't be that diff'cult!

Thanks

[flexcoders] Time Slider function problem

[g_vaccarezza]

Guys, I'm trying to pul a time range selector so I can trim down the 
data I show in a graph.

I copied the example from the charting explorer and my change function 
goes like this:

function sliceResults():void {
   slicedResults = myData.lastResult.data.month.slice(slider.values
[0],slider.values[1]);
}

I dataProvide my chart with slicedResults, but it isn't responding. 
It's like I'm using the slice property the worng way or something.

Anyone had a similar problems? solutions?

Thanks!!

[flexcoders] Newbie: Dataprovider sintax for column series with xml dataprovider

[g_vaccarezza]

Guy,

I'm a a total dumba$$ trying to fill my column chart with my xml
dataprovider; I have so many doubts but let's concentrate in my current
problem:

I have a column with several series. I should like like this:

http://www.idslab.com.ar/tmp/chartShot.jpg


And my dataprovider looks like:


-  
 
  -
 
   -
 
  


So far, so good. I want to see those payornames displayed in series by
month.

Now the question: I know that I need to add series for each one of the
payornames I want to dispay, but I'm having trouble writing my
dataprovider declaration. It's more a sintax problem than a theory
problem, and it's driving me mad.

How shoud I declare the dataprovider for my column chart and each one of
the series? I still don't get how to properly "link" the xml structure
to work as a data provider so that I can pull the chart as shown.
Should it be something like dataprovider="myData.lastResult.data.month"
or dataprovider="myData.lastResult.data.month.payorname"... (none of
thos 2 is working correctly anyway).

Thanks for your help!

[flexcoders] Re: loading a external variable into a flex app

[g_vaccarezza]

greg,

I'm effectively calling initApp() as 



I also changed the HTML code for both the regular html and the debug 
html (since I didn't know which was the "right" one, I changed both). 
Really winder what's going on!

As for the checkpoint or a trace() statement...
I'm having a hard time getting around flex debugging... I'm a Flash 
user and I'm used to the test movie enviroment (ctrl+enter) where I 
can easily use the output window to check for traces...
I know this is completely retard but I can only test my flex apps in 
the browser which ain't really helpful. I wonder if there's anything 
like a test enviroment within flex?

Thanks a lot!
Guille

[flexcoders] Re: loading a external variable into a flex app

[g_vaccarezza]

Hi G!

Code seems to be fine, but it ain't seem to be working. I wrote the 
following code withing Flex:

// call on creation complete

private function initApp():void{
   myExternalUrl = Application.application.parameters.theUrl;
   requestText.text = myExternalUrl;
}

and then, within the  tag in the HTML:



I open the HTML witht eh Flex app, but the textbox wont show anything.

Any Suggestions?
Thanks!

[flexcoders] loading a external variable into a flex app

[g_vaccarezza]

Guys,

I got to externally set a variable on a swf.
I have very limited knowledge but I do know that in a regular flash 
movie I can set a variable through a declaration within the object 
ember tag in the html:

myMovie.swf?variable=something

or through the  tag:



Does this apply for an embedded flex movie? In that case, how should I 
read the variable from within flex?

Thanks!

[flexcoders] Column series and XML

[g_vaccarezza]

I'm using and xml through and HTTP service. The xml looks like this:



   
   


   


   
   


   



I need to make a Column chart with 2 series, one for each of the 
payorname tags. I saw examples over the web about how to make series, 
but ther usually "hardcode" the series ids, ie:




 

and that's not use to me since I need to make the series dynamic (in 
the future, they could add more payornames to this same XML.
I can't find a useful tutorial, hopw anyone can help me out with some 
tips!

Thanks a lot!,

[flexcoders] quick HTTP service question

[g_vaccarezza]

Guys,
I'm reading an XML through a HTTP service. I'm sending request to a 
database to retrieve a new xml from the same URL (so I'm using the send
(); function).
I need to trigger an event once the newly requested XML fully loads on 
flex (for instance, once the new xml loaded, I call some function).

I know this has to be something basic, but I don't know where to start!
Sorry for being such a newbie!

Thanks

[flexcoders] XML manipulation

[g_vaccarezza]

Guys, I got this xml



   
   


   
  

   
   


   



I need to fill a column chart with all the payornames in the X axis 
and their TOTAL (sum of) volumes on the Y axis.

Payornames get repeated on each month, so I have to add them up for 
all months (i.e. ABD Co total would be 47).

I kinda know how to do this on AS but I have no clue how to "flex-it" 
in my mxml.I used 

dataProvider="{myData.lastResult.data.month.payorname}" 

But i get and error, seems that flex can figure out I want to sum all 
the payorname volumes for all months.

Any help will be welcome!!

[flexcoders] Array.slice problem

[g_vaccarezza]

Hi guys

I got this :


  {myData.lastResult.data.month} 


If I:

trace (results[3].label)  // Yields April, cool

But If I:

private function sliceResults(): void {
   [Bindable] public var slicedResults: Array = new Array();
   slicedResults = results.slice(1,3)
   trace (slicedResults.toString); 
}

I compile the mxml, and when I call the function, I get the following 
output error:

Error: Unknown Property: 'slice'. 
atmx.collections::ListCollectionView/http://www.adobe.com/2006/actions
cript/flash/proxy::getProperty()...bla bla bla

Any ideas what this could be? Isn't results supposed to be an array?

Help me out! thanks!

[flexcoders] Hslider problem

[g_vaccarezza]

Guys,
I got this XML








I want to make a time range selector for a column chart. I copied 
this code from Macromedia's webblog: 
(http://weblogs.macromedia.com/flex_samples/charts_explorer/line/LineS
lider.mxml)



AS:

private function getSliderLabel(value:String): void {
   ### return results.gen[parseInt(value)].label;
}
private function sliceResults(): void {
slicedResults= myData.lastResult.data.slice(slider.values
[0],slider.values[1]);
}

MXML:



{myData.lastResult.data.month} 




Unluckyly, it ain't working...I get and error on ### that says:

"The resturned value must not be defined"


Any ideas?
Thanks!

[flexcoders] list >> selectedItem question

[g_vaccarezza]

Hi guys:

I got this XML:











And the list:

   

I need to make multiple selections in the list and retrieve each 
item's label in order to send a request to a data base.

Using selectedIndices only retrieves items positions. 
If I use selectedItems and the next AS:

trace (selectedItems.toString())

I just get a [Object object] thingy...I can't seem to be able to 
retrieve each item's label...

Any suggestions? DO I need to go a step further and use additional AS 
to solve the problem or is ther a way to get an array of the labels 
directly (something like selectedItems.label)?

Thanks!
-G

[flexcoders] Array question

[g_vaccarezza]

Hi!
Suppose I have the following array:

var myPets_array:Array = new 
Array "cat", "dog", "fish", "canary", "parrot");

Is there a way I can retrieve several objects from the array at one 
time?
For example, I want to know whats on myPets[1], myPets[3] and myPets
[5] at one time.
Is there anithing like 
trace (myPets[1,3,5]) ??

With slice I can retrieve a range of elements, but I want to retrieve 
things in a non-linear way...
Thanks!

the form's action page:

?items=Wallet&items=Hat

Quetion: How do I emulate this when calling an action page via a Flex
HTTPService object?

This is what I've tried so far:

1. Create a Flex List object with allowMultipleSelection = true
2. In the ActionScript that invokes the HTTPService, I put something
like the following:

var params:Object = new Object();
params.items = listControlInstance.selectedItems;
httpServiceInstance.send(params);

What Flex submits to the action page is the following:

?items=Wallet,Hat

...which breaks the action page.
What is the correct way of doing this?

[flexcoders] Re: Loading External XML error

[g_vaccarezza]

Thank you! That worked!
How come the livedoc provides buggy info? Seems that the loader has 
to be inside a function to work...

[flexcoders] Loading External XML error

[g_vaccarezza]

Hu guys, I'm a newbie to flex so any help is welcome. I'll be brief:
I want to load and manipulate an XML file into my flex enviroment so 
I went to the live doc and copy-pasted the following code within my 
 tag:





I get a compiling time error at lines 4 and 5. It says:

Access to undefined property loader
Acces to undefined property request
Access to undefined property onComplete

:O Any ideas what this could be and how to solve it!?

Thanks!
Guille

[flexcoders] Charting in Flex with drill down & complex XML

[g_vaccarezza]

Hey guys, ok, whoever has the time and the patience to help me, I will really appreciate it!My name is Guillermo Vaccarezza, and I've purchased Flex 2 recently to use it for a project I'm developing in my Studio in Argentina. This mail is to make you a consulting on some doubts I have on Flex. Hopefully you will be able to clarify my doubts or at least tell me a good place where to find nice charting tutorials for newbies, specially on the drill down capabilities flex offers and XML data filtering: The application I'm working on is a statistics graphs dashboard for hospital use. Summing it up, hospital will use this application to upload data about their ORooms, amount of procedures done by day, doctor who performed the procedure, time taken for each one and so on. All this data is compiled into a PHP based database that then delivers a BIG XML to process in Flex and show, for example, a volume over time bar chart, in which you should be able to drill down in a particular month and then see another graph showing the volume over procedure axis but with the doctors on the X axis. There will be many reports, each one with their own peculiarities, but following a similar logic. Also, and most importantly, there will be a filtering tool before visualizing the graphs: a tab-based box where to chose which ORs you want to see, or what doctors, of by what specialy, etc. Once you make your selections, you click an UPDATE button and you visualize your chosen report with the filter applied to it, then you drill into the data as I explained before.I'm new to flex, and even thought it seems to be a pretty straightforward tool. And I'm intermediate flash 8 user (my site is idstudio) , I'm still having problem on HOW to access my XML file and take what I want from it (depending on the applied filters), then render only those XML nodes on the graph.Let's go to the first question, this concerns the drill-down capability for my chart:For instance, let's say I have the following XML:---Now, on the first bar chart, I want to show volume over time per month. That I could do pretty easily seeing some examples on the web. Now it comes the second graph, which is a drill down on the first: I want to click one month, and then see all the volumes per procedure for that month. On the paper, this seems easy; however, I just can't find a good tutorial on how to bind data and what actionscript code I should need to use to go from graph 1 to 2 using my XML structure. The help on flex documentation doesn't give any practical example of data drill down for charts... :(The second question is about the filtering tool I want to have the users click on before displaying the graphsLet's take a look at the XML: I want to only see the first procedure on the first month and only 2 of the 4 doctors for that procedure, for instance. Also, suppose that the user clicks on procedure 1, but then clicks on a doctor that doesn't belong to that procedure, so the data retrieval is not applicable, so I should show a warning or a red flag telling the user that his request is not applicable….How exactly can I manipulate my XML in order to retrieve only the data I want to show? I've been going crazy looking for an example that helps me on this without getting too difficult on the actionscript part, but I couldn't find anything helpful...-I know this is a long post and you won't probably have the time to tutorial me on all I asked, but at least some help would be terrific. If you have some tutorial on the internet you can recommend me I would really appreciate it...The idea is to have a simple tutorialized example of a bar chart, with a drill down capability, the MXML file and the XML file used for showing the data. On the other hand, having some example of the filtering tool for manipulating what data to be shown would be awesome. I found some examples of what I'm looking for on http://flexapps.macromedia.com/flex15/chartexplorer/explorer.mxmlBut the drill down example doesn't show me the XML file, so I can't know how they have the data structured so to compare it to my XML. Besides, these examples are from FLEX 1.5, and the syntaxes changes when migrating to flex 2, so this MXML files are not behaving really good when I try them on flex 2.Ok! That's all for now, I hope you'll be able to bless me with some of your knowledge, thank you so much in advance guys! -g
