[flexcoders] Moving ROs CFCs from Flex - Flash CS3
So I'm experimenting with moving my RemoteObject development to Flash CS3 instead of Flex. My main reasoning for this is filesize (300KB min with Flex vs 15KB min with Flash). Here's my problem. I currently use CFCs. With Flex, as long as the swfs are on the same server, I can set my CFCs to access=public. Moving the CFCs out of the root is unfortunately not currently an option. In Flash CS3, I'm using an RO wrapper I found from http://www.bytearray.org/?p=122. It returns an error saying that my CFCs are not remote. Setting the CFC to remote fixes the problem, but then leaves open the CFC for anyone to access. Is there a solution to this? I would be happy either with smaller Flex swfs or being able to access non-remote CFCs with Flash.
[flexcoders] DataGridColumn - vertical styling...
How can I set a selction style that runs vertically AND horizontally in a DataGrid? i.e. selecting a cell by default selects the entire row. I want one that selects both the row and the column.

[flexcoders] Effect on VBox with Repeater...
Stupid question here probably, but I've been struggling with effects and generally doing visual design in Flex. OK - I have Vbox. Within it is a repeater. The component repeated is just a line of text and an image. I have rollOver and rollOut styles applied that will highlight the text by making the backgroundalpha of the component 0-1 and the text changes color. However, I would like to have an effect that fades out the entire Vbox and its children, including the repeater and all of its repeated components, and fade back in. When I apply the sequenced effect (animate alpha property on the VBox) it only fades in/out the single highlighted repeated item. How come?
[flexcoders] Detect text wrap?
I have a collection of vertically placed TextInput and TextArea boxes. I'm using a resize function that manually resizes each of the boxes' heights depending on the amount of text that is in each, so that there's never any extra space, and all of the text is always displayed. Since these are editable, the problem is when a user is typing in new text, and they go past the height of the box. I'd like to stretch the box vertically as they are bringing in new lines. Any way to detect that and re-run the resize function? I suppose I could do it on change, but that seems a bit extreme doesn't it?

In the case of the swf being loaded is a Flex2 app, you can use the SWFLoader control.

[flexcoders] Event Dispatching through more than one component
I'm still messing around with custom events. If I have a popup embedded within another popup and want to dispatch an event from the top-most component down to the parent application, do I have to dispatch it to the first popup, and then redispatch the same event to the parent app? Is there any way to dispatch an event, but have it automatically go through all components down to the root? Obviously I've tried, but events seems to stop at the parent component, and they are not automatically delivered to their parent's parent, etc. What I'm thinking of doing instead is having each popup send a message to the root to open other embedded popups, so that they are ALL created from the root application rather than the popup. In essence, a custom popup manager. But I'm still curious if there's a way around the above scenario. Thanks, - Chris

How do I dispatch the CloseEvent.CLOSE manually? And if I have more than one popup, will it close all of them?

[flexcoders] Custom Event Handler from Popup?
So I'm still trying to dig through all of this OO stuff. Its been
tough!
I've made a couple of custom events from views. The handling I've
learned is usually like this:
view:CustomComp somethingReturned=handler(event)/
But I have one that is a popup. The popup is invoked like this:
private function showPopup():void {
var myPopup:customPopup = customPopup(PopUpManager.createetc)
myPopup.passedVar = somethingPassed... etc
}
The popup has a custom event that is dispatched on closing the popup.
How can I create a handler for it? myPopup.somethingReturned = handler
(event) returns an error in Flex. If I make the popup a view in MXML,
the event handler works fine.
[flexcoders] Re: Getting selectedItems to properly *select*...
Got it! It appears that selectedItems is dependent on the data being *absolutely identical* to the dataProvider. And while I thought my data was identical, it really wasn't. In the debugger, if you look at a variable, its always: Array (@123456). What I found was that although the data was definitely the same, that number was not. To fix the problem, I centralized all data to go through one data manager, whereas before I was reinitializing a different data component in each component. So now, I'm basically calling parentApplication.dataManager.someFunction () from all of my components. This isn't good quite frankly, but by doing so, the @123456 is always the same. If anyone else can think of a better way, I'm all ears...

As mentioned in earlier posts, the items in this found array have precisely matched data to the dataProvider of the grid, and the selection still doesn't occur, without any errors either. The *only* difference between the two is the @123456 following the Array description in the debugger.

When the user clicks on Grid A (not multi-select), Grid B's selectedItems is populated with the second-level AC anotherAC, like this: gridB.selectedItems = gridA.selectedItem.anotherAC.source And it works! BUT!!! When I select another item and come back to the first one, the anotherAC level has disappeared without a trace! It disappears from all bound ACs. WTF?!

[flexcoders] Getting selectedItems to properly *select*...
I have a very odd problem, related to some other unanswered posts here. An application has a popup window called on click that is using data from a custom event. The popup has a datagrid. The get all data for the grid is coming from a simple data management component, called inside the popup - lets say an AC allData. The data manager inside the popup brocasts an event saying done loading and I'm handling that event in the popup to select selectedItems based on the data passed from the main application. The selectedItems data is definitely available to the popup. It is an AC of myValueObject. The get all data is definitely there and showing in the grid. Its also an AC of myValueObject. In the above scenario, it doesn't work when I say DG.selectedItems = selectedData as Array. Instead, I have another function getSelection (selectedData) which basically loops through the selectedData AC and pushes each item to a new Array. I've triple checked this, and it also does not work. As a test, to make sure its not realted to the loading process of the popup, I've even set the getSelection to run via a button click well after everything is in the popup. It selects nothing. BUT! If I say DG.selectedData = getSelection(allData), where allData is the same thing used to populate the grid's dataProvider, it selects all items in the grid. What's totally odd, is the AC from the dataProvider and the AC for selectedData look absolutely *identical* in the debugger, minus a bunch of items for the selectedData, as it should be. The only working alternative I can find is to create another function in the data manager that re gets the selectedData. This is not doable, because other areas of the application might change the selectedData, without calling to the database. I need to keep moving that data around to components freely without calling him. Any thoughts on what's wrong here?

[flexcoders] java.lang.Runtime complete message?
So I'm developing a simplified Flex2 application that allows a user to upload video, and a serverside conversion is made to flv via ffmpeg. The back-end code is windows-based CFMX7. Basically, after the video is uploaded I'm running a cfc function that takes the filenames and runs it through ffmpeg.exe via: myobject = createObject( java, java.lang.Runtime).getRuntime() myObject.exec(ffmpeg.exe) etc. This is done as an alternative to cfexecute. It WORKS - the file converts and everything, but: 1) it converts very very slowly - the server's performance monitor shows a very low CPU usage, and 2) I don't know when its finished. Is there any way to monitor when the exec is complete and send a flag to Flex2? Or perhaps, when someone tries to view the video, Flex can check to see if the process is done or not? I'd like to stay away from using FDS.

If I remove checkProcess and return startProcess instead, I have some kind of java string - a thread identifier or something? i.e.: [EMAIL PROTECTED] Its really quite simple - I don't know enough about java to make this happen and the Java reference perplexes me when in-context with Coldfusion.

There's eight webservice calls when an app is first loaded. One thing I did notice is that the order of these calls appears to differ depending on the session. I didn't think that any one service call requires another, but considering the sporadic nature of the errors, is it possible that the problem here is that simple?

Finally got it tho, and here it is!! The trick was just
understanding when to end the statement, and when to check
something first or last. Its basically:
1) Still not sure what the first line does, but its comparing the
text of my search box with one column in the grid. If the text box
has nothing OR has something, it passes either way.
2) If the first combobox is NOT Show All, and the second combobox
IS Show All, then check the first combobox
3) If the second combobox is NOT Show All, and the first combobox
IS Show All, then check the second combobox
4) If BOTH comboboxes are NOT Show All then check BOTH comboboxes
5) If BOTH comboboxes ARE Show All then check nothing.
Surely there's an easier way to implement this, but darnit, it works!!

column. Wish me luck, ;)

[flexcoders] Processing Filedata / Filereference with a CFC instead of CFM?
I'm using a component from eFlex, called Uploader. Has anyone else
run into this? Its really quite brilliant and was a breeze to
implement and customize for my own needs:
Go here: http://www.everythingflex.com/
and search for Uploader.
But, from what I understand, the cfm processing for this, is the same
as any other methodology when using Flex and Coldfusion for uploading
data. The CFM I have that works, is a single line:
cffile action=upload filefield=Filedata destination=#ExpandPath
('./logos')# nameconflict=OVERWRITE
Can someone show me an example of this when used with a CFC instead
of a CFM? I want to do some checks and balances in ColdFusion before
physically using the cffile, and if those checks don't validate,
return an error message to Flex. Is that possible? In fact, one
problem with this component is when an upload error occurs, no
message is sent to the user.
What follows is the getFile() function found in the Uploader mxml.
Thanks,
- Chris
public function getFile():void {
if(this.uploadToURL.length 0){
this.uploadURL = new URLRequest();
this.uploadURL.url = this.uploadToURL;
/* uploadURL.url is defined per component instance and leads to
the CFM for processing */
this.file = new FileReference();
this.configureListeners(file);
this.file.browse(new Array(new FileFilter(Images,
this.imagesFilter)));
} else {
Alert.show(uploadToURL is undefined, Syntax Error);
}

[flexcoders] Simple Flex2 Security?
I have an application that has two states (View and Edit), and one button toggles between the two states. There are a few components, but none of them are required for the non-logged-in state. Can someone recommend a methodology for implementing some very simple security in he main app? i.e. typing in a username/password (or maybe just a password only), and on success, enabling the button that toggles the states. It seems that most articles I've read on the topic are at a much higher level, but not all of us are building enterprise level Flex apps. I don't have FDS, I can't use RemoteObject on my server (HostMySite), and I'm using ColdFusion 7.01 on the backend. Thanks - Chris
[flexcoders] Re: TitleWindow Component...help!
I've developed a test mxml file of the current combobox note updating
problem at hand.
In the following example, click Fill Data. The combobox's data fills
up. Choose either the first or second item in the combobox. Now click
the associated Rename Data button for the item chosen.
Notice that nothing happens? But wait, if you click the combobox to
open it, you'll see that the data was in fact updated, but we're just
not seeing it.
Now change the ComboBox to a DataGrid. Everything works fine.
What gives?

OK - If I reassign the ArrayCollection (and retell it what the

But seriously, there's got to be a better way than that. Otherwise,

[flexcoders] Re: TitleWindow Component...help!
Well - what I've done, after finding a titlewindow example on cflex,
is create a public variable in the titlewindow component of the same
name as one in the application, and I send it to the component from
the main app AND back via the title window's instance variable. i.e.:
TitleWindow Component:
[Bindable]
public var aListOfData:ArrayCollection;
private function sendData():void {
- runs when you click submit in titlewindow
var compilation:Obect = new Object;
compilation.setting1 = something in component;
aListOfData.addItem(compilation); (or setItemAt, etc)
}
Main Application looks like this:
[Bindable]
private var aListofData:ArrayCollection;
private function openComponent():void {
- runs when you click open window in the main app
var openingWindowblah blah, opening the TitleWindow;
openingWindow.aListOfData = aListOfData;
}
OK - so those variable names are random thoughts off the top of my
head, bu you get the picture. From what I understand, this doesn't
follow the idea behind loosely coupled components, but is there
anything really wrong with this methodology? It seems to work very
well in my case. I can even have a window within a window, all
passing variables between windows, all the way down to the main app
quite easily, and so far its been a breeze to setup.
Thoughts anyone? If I continue down this path, where will I start to
run into problems?

look like it - the displayed label hasn't changed. Clicking the
combobox to open it, you can see that the selected label and data
are
in fact updated. Closing the combobox without choosing anything
updates he label correctly. How come its not immediately updated
when the AC is, like the datagrid?
Tried refresh() on the AC just before closing the window, but that
didn't seem to do anything. Not sure what else to try!
Thanks all,

So wrong? No. Best practice? It depends. Think ahead.

Subject: [flexcoders] Re: TitleWindow Component...help!
Well - what I've done, after finding a titlewindow example on
cflex,
is create a public variable in the titlewindow component of the
same
name as one in the application, and I send it to the component
from
the main app AND back via the title window's instance variable.
i.e.:
TitleWindow Component:
[Bindable]
public var aListOfData:ArrayCollection;
private function sendData():void {
- runs when you click submit in titlewindow
var compilation:Obect = new Object;
compilation.setting1 = something in component;
aListOfData.addItem(compilation); (or setItemAt, etc)
}
Main Application looks like this:
[Bindable]
private var aListofData:ArrayCollection;
private function openComponent():void {
- runs when you click open window in the main app
var openingWindowblah blah, opening the TitleWindow;
openingWindow.aListOfData = aListOfData;
}
OK - so those variable names are random thoughts off the top of
my
head, bu you get the picture. From what I understand, this
doesn't
follow the idea behind loosely coupled components, but is there
anything really wrong with this methodology? It seems to work
very
well in my case. I can even have a window within a window, all
passing variables between windows, all the way down to the main
app
quite easily, and so far its been a breeze to setup.
Thoughts anyone? If I continue down this path, where will I start
to
run into problems?

Dataprovider for the combobox is an ArrayCollection of data: data and label. User clicks a button, TitleWindow pops up. 2) User types into a text box in the window, clicks Submit. 3) The text is a passed as a label, along with a generated ID (generated in the component) and is added to the combobox's dataprovider. The problem appears to be that there is no handler of the Submit button click on the main application. Obviously, I would add to a datasource and return an ID from that, but I can't even get this to work manually (i.e. for testing purposes, setting a static data and label). Just trying to keep this as simple as possible. Seems to me that if I can pass a string of text, I should also be able to pass an Object that is added to a dataProvider in the main app? Right?

Perhaps a more specific example will help with my question... I'm digging through the Flex2 docs and found the textDecoration property of the DateChooser. Seeting this to underline will make ALL dates in the datechooser have lines under them. Given the original scenario, is there any way that I can apply this property to only a specfic collection of dates through something like a for loop? i.e. loop through the ArrayCollection, and for each date found, underline the specific matching date in the component, but leave the others alone. --- In flexcoders@yahoogroups.com, qnotemedia [EMAIL PROTECTED] wrote: I have a calendar component and an ArrayCollection of data that is filtered depending on the selected date of the calendar.

[flexcoders] CF/Flex2 connectivity differences between DataGrid and Tree
I'm working on a new Flex2/CF app. My first had a tree that received XML, and I had it setup to edit each node, and one button would send the entire Tree back to CF. I'm having a little trouble doing something similar with a DataGrid. In the new app, I'm seing a query from a datasource as an array of structs to a DataGrid. How can I send this entire datagrid back to CF? In my first app I sent myTree.value via webservice request and parsed the XML. Sending datagrid.value isn't working however. Changing it to datagrid.selectedItem.columnName works, but then I'm stuck with clicking a button for every single item in the datagrid, rather than sending the entire grid at once. It seems that there's something fundamentally different between grids and trees that I'm not quite understanding.

[flexcoders] As you type Grid Filtering with Textinput and Combobox
Hi all - I'm trying to mix together two blocks of code:
Ben Forta's As you type Grid filtering:
http://www.forta.com/blog/index.cfm/2006/7/13/Filtering-Data-In-Flex
Filter a Grid with Combobox:
http://www.cflex.net/showFileDetails.cfm?
ObjectID=415Object=FileChannelID=1
I have successfully implemented either one or the other, but can't
quite get both to work at the same time. What I have so far is
below. The application has a datagrid's dataProvider bound
to objectList - it has an objName field for text search and a
typeName field for the combobox.
The combobox is cbTypeList and the textinput is searchText.text.
Both have change=objectList.refresh()
If I use the code below, the combobox still filters, but the textbox
typing does not. If I remove either set's function, they each work
fine on their own.
private function resultHandlerGetAllObjects(event:ResultEvent):void {
objectList = event.result as ArrayCollection;
objectList.filterFunction=processFilter;
objectList.filterFunction=typeFilter;
}
/* http://www.forta.com/blog/index.cfm/2006/7/13/Filtering-Data-In-

private function processFilter(item:Object):Boolean {
var result:Boolean=false;
if (item.objName.length == 0 || item.objName.toUpperCase
().indexOf(searchText.text.toUpperCase()) = 0) {
result=true;
}
return result;
}
/* http://www.cflex.net/showFileDetails.cfm?
ObjectID=415Object=FileChannelID=1 */
private function typeFilter(item:Object):Boolean {
var result:Boolean=false;
if(item.typeName == cbTypeList.selectedItem.typeName) {
result=true;
}
return result;

[flexcoders] Re: Flex Books? Suggestions...
This is a great topic that needs to stay alive, as books and tutorials are just now showing up now that Flex2 has been officially released. lynda.com has a Flex2 Essential and I sat through most of it. It might be too noob for some, but it covers the bases really well. Looks like the official Macromedia books won't be out until later this year. Also, definitely check out the sites listed in the FAQ. cflex.net has particularly been useful for me. - Chris --- In flexcoders@yahoogroups.com, Marcelo de Moraes Serpa [EMAIL PROTECTED] wrote: There's the RIA book that's currently in it's pre-release stage.

[flexcoders] Success!!! But I still need help!! (RE: Custom scrolling with TileList)
Well - never received a reply to this thread, but I've figured out how to get the look, feel, and interactivity that I wanted via lots of nested Canvas', HBox's, VBox's, etc...Here's what I've basically done. Again, the goal was to make a vertical TileList with component itemRenderer, that scrolls smoothly, and rather than using the default scrollbar, create my own scrollDown and scrollUp buttons (with no scrollbar actually available - just the buttons). - I have a TileList of course, and its height is dynamically set to the number of items in the itemRenderer * 125 (an item's height). scrollingPolicy is disabled. With 75 items that makes its height. - itemRenderer consists of an image and label. The images can be large - width of 640 - and are scaled down via maxWidth/Height. - The TileList is within a VBox with scrollingPolicy disabled. - An Up/Down button calls a function that sets the verticalScrollPosition of the VBox to += 20 or -= 20 via buttonDown with autorepeat. This creates the effect of a nice smooth scroll! PROBLEM I need help with now: Performance has become an issue. When the TileList contains 75 thumbnails, that makes its height nearly 10,000 (75*125)! The problem is that, to Flex, the entire list is being displayed, whereas when you normally display a smaller sized TileList, items are not loaded until they are physically displayed by the user. When it first loads, it really chokes up cause its calling to load every single thumbnail in the list all at the same time. Is there any way to fix this!? - Chris -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!

[flexcoders] Custom scrolling with TileList
I have a vertical scroll-only TileList. Is there anyway to:
1) remove the scrollbar, and
2) Use buttons at the top and bottom of the TileList that scroll the
list while mouse over?
As a test, so far, I have a skinny and short TileList with a bunch of
items in it. When you mouseover a button it runs a function with the
following code:
while (tileListing.verticalScrollPosition 5) {
tileListing.verticalScrollPosition =
tileListing.verticalScrollPosition + 1;
}
Unfortunately, this obviously has the following problems:
a) The code runs so fast that the list jumps. Is there any way to
make the movement slow?
b) How can I get the maximum length of the tileListing's dataProvider
(i.e. to replace the 5 in the above example).
c) In the end, I'd like the scroll to stop based on both the
mouseOver and the tileList's dataProvider length. Is there a
button.mouseOver == true type of condition?
Thanks!
- Chris

[flexcoders] Re: Custom scrolling with TileList
Still fudging my way through the Flex2 reference...here's another
possibile method to do this?
mx:Sequence id=scrollDown
mx:AnimateProperty property=verticalScrollPosition
fromValue=1 toValue={maxVerticalScrollPosition} duration=1000 /
/mx:Sequence
...which I can bind from tileListing's mouseDownEffect but there is
no mouseOverEffect, and even then, it would occur anytime a mouse is
over the entire list, not just an area of it. This is also still
scrolling one complete item at a time, whereas I thought it might be
possible to have a smooth scroll...no?
I also tried binding the sequence to a button, and then making the
propety tileListing.verticalScrollPosition but this throws an error,
as it appears that the animation must occur on a property of the object
that is bound to the sequence.
Closer tho...any thoughts?

Didn't have a chance to try that - but it makes sense.
In the meantime, I moved to a webservice and just call a CFC to re-read
the XML. Not ideal, but it works, and since this isn't a critical app,
I'm going to move on.
Thanks for the replies.

[flexcoders] Re: Component access to dynamic application variable
So create a variable (rootURL) in main application. When you create dataProvider for TileList, pass this variable to thumbnails via dataProvider. Abdul - could you show me some basic code for this? To be clear, in the main app, I currently have: a) HTTPService, retrieves xml file (layed out as root.folder.file b) ComboBox, dataProvider=HTTPService.lastResult.folder c) TileList, dataProvider=ComboBox.selectedItem.file, itemRenderer=view.Thumbnail d) view.Thumbnail Component, has an Image with [EMAIL PROTECTED] So when we get to step d, the Thumbnail component only has fileName available. The folder/complete path is in the root node ([EMAIL PROTECTED]). I understand that I can call a function via comboBox change (and the ResultHandler on returning the service), but how do I add a variable to the repeating file node before its sent to the TileList?

[flexcoders] ArrayCollection...how can I edit the data?
Hi all - I'm still running around in circles trying to get a certain type of functionality from CF/Flex2. I have a Coldfusion CFC sending data to Flex2. I've been fine doing this in a number of ways - HTTPService read from xml built by CF, or a WebService reading an array return from CF, etc. What I'm having trouble with is 1) editing the data returned in the Flex GUI as an ArrayCollection, and 2) Successfully returning the AC to CF for re-processing. Case in point - these first three steps I've gotten to work fine: 1) Flex2 app sends a text string variable of a path to CF via WebService 2) CF writes the data as an xml file, and then returns a *multi-level* result of the path's directories and files as a multi-level array of structs to Flex2. (This is actually an array.struct.array.struct layout - long story, but it works). 3) After the return from CF (as ArrayCollection), the Flex2 GUI has options for displaying a listing of the folders (listed in a combobox) and files (listed in a datagrid). User selectes a folder, and datagrid repopulates correctly. --- What I can't accomplish: 4) Edit any field of selected data in the ArrayCollection via various TextInputs. I've tried many things. The only thing that works is editing the values of the Flex2 objects (the combobox or the datagrid). This is not ideal, since in step5, I will have to rebuild from multiple variables. How can I edit any of the items available form the ArrayCollection? 5) Return the edited (or ANY) ArrayCollection to CF as something it can read (which will later pass through a cfxml tag loop).

[flexcoders] Refresh Tree from HTTPService
I have an HTTPService that imports a multi-level xml file, and a tree
with dataprovider={httpservice.lastResult}. How can I refresh the
tree when the XML data changes?
I've tried just rerunning httpservice.send() via a resulthandler or
a refresh button but neither seems to work. The changed data does
show correctly when I reload the app.

[flexcoders] Component access to dynamic application variable
I'm currently learning how to utilize components. In a slideshow app, I have a thumbnail component (image) that is rendered by a TileList in the main application. dataProvider in the TileList is being used to supply the path, image name, etc, by sending a repeating node of an xml file. However, I'd like the thumbnail component to also be able to read a property of a selected parent node (via a ComboBox in the main application) of the data its receiving. Can I make a bound variable in the main application dynmaically accessible by the component? The xml is basically laid out as root(i.e. URL to root).album(i.e. folder name).image(i.e. filename), and any time I render an image, I'm recollecting the various nodes to produce an absolute URL to the image. Hope that makes sense...still learning my Flex2 terminology. - Chris -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!

[flexcoders] Send Tree data to CF
Hi all - a bit of a newbie here, but I'm coming along with some basics in Flex2 / CF7.02. I went quite far with CF Flash Forms, and am ready to dig deep into flex. I've successfully learned how to load XML data to a tree and make it look right (using httpservice). The original external xml file I'm using was written from cfxml in CF. But I'm a bit stuck with trying to send data FROM Flex2 over to a cfc for manipulation. Most tutorials simply run functions, but don't pass any data to CF. I'm currently loading a cfc via Webservice. A button's click parameter is set to run a function in the cfc (i.e. myService.sendData (myTree.selectedItem)). Based on that could someone write me some basic cfc code (and/or mxml if needed) that can receive this data and place it in a CF array - or at least lead me in the right direction to a tutorial online? Once manipulated, the tree will be written straight back to xml via cfxml, then re-read via the Flex app's httpservice - i.e. kind of like saving your settings. If there's a better way to do this, I'm all ears!
