My custom item editor opens a titlewindow (too much stuff to show in an inline editor) which obviously steal the focus, so I get a itemeditend event and the datagrid destroy the editor at the wrong (for me) time. I think to have to keep the itemeditor alive until the titlewindow job is done, but how? DataGridEvent reason is "other" and livedocs said preventDefault() can't help.
View 1 RepliesI need to run some code when a panel is destroyed. The code is simple, I have some Background tasks while it is opened, but need to stop them when closed.
I have a Close button for the panel, and I stop the BG Tasks when the user wants to close the panel, the problem is that they have access to a top menu bar too and can jump to another application module/part throught it, so, the user can exit the panel (when exiting, the panel is automatically destroyed) but the panel close event code is not executed because the close button was not pressed.
One solution could be to inherit from panel and add a post step method that is called when swapping modules, etc... So, if the user wants to move to another place through the menu bar, my system will first call sometihng like PreEnd() method on the panel and everything will be solved. But, is there any event that I could catch from the panel when it is destroyed to accomplish this? I have been checking the documentation but couldn't find anything useful to achieve what I explain.

View 1 RepliesI have a DataGrid, with itemEditor as NumericStepper in a few columns. When a value in the DataGrid is edited, I would like to update several values displayed on the screen, and so want to call a updateValues() function.First, I added this function to itemEditEnd event of the DataGrid, but the function is getting called before the new value is updated into the dataProvider and hence, the values I have in the function are the old values. Is there any other event that is fired after the values are updated into the dataProvider? or am I missing something?Second, I tried putting this function in the change event of each itemEditor (duh!), but then again, the change event is fired, but the values in the dataProvider are the old ones.Is there any way I can make the function updateValues() be called, every time a value is edited AND updated into the dataProvider, because there's where I am taking the values from?

My tweak that I am trying to acoomlish, is to have a custom itemEditor that is a form with two TextInputs and an OK button. For the life of me I can't get that button to trigger the DataGrid's itemEditEnd event where I have some processing before I call destroyItemEditor. I tried dispatching the event myself directly but got a strange error in DataGrid's updateDisplayList saying editedItemPosition was null (editedItemPosition.rowIndex).
I'm trying to use the Spark DropDownList as itemEditor in an AdvancedDataGrid. Howerver, I've stumbled onto two issues:Clicking on a item in the DropDownList changes the selected row in the ADG. You can see this behavior by compiling the code from below and executing the following steps.The value changes from "A" to "C" and Row 3 is the selected row in the ADG. It looks like the mouse click in the DropDownList is also handled by the ADG itself which changes the selected row accordingly. I couldn't figure out a way to prevent this. The expected behavior would be that row 1 is still selected after the DropDownList has been closed.Clicking on the scrollbar of the DropDownList closes the DropDownList. (I just found the solution to this problem in the relatated questions while writing this: Scrollbars in dropdownlist inside DataGrid itemEditor not working)

When not editing the cell, it shows a centered date as plain text. When editing, it shows a DateField editor. The second example is exactly the same as far as I can tell, other than the fact that it is an AdvancedDataGridColumn. Using that code with an AdvancedDataGrid, when I go into edit mode I can see the text from the normal item renderer behind the DateField editor (between the text input and calendar icon).
Example 1:
<mx:DataGridColumn id="endColumn"
dataField="endDate"
headerText="End"
[Code]....
Is there anyway to create a custom item editor based on the dataField value? For example:
<mx:DataGrid editable="true" dataProvider="{_actionArr}" id="prop">
<mx:column>
<mx:DataGridColumn headerText="Component" editable="false" dataField="label"/>
[code]....
I have a datagrid column as follows:
<mx:DataGridColumn
headerText="Description"
dataField="description"
editable="true"
editorXOffset="2" editorYOffset="2"
editorHeightOffset="20" editorWidthOffset="60"
itemEditor="com.jono.controls.DgItemEditor"
wordWrap="true"
/>
And a very simple DgItemEditor:
<?xml version="1.0" encoding="utf-8"?>
<mx:TextArea xmlns:mx="[URL]" wordWrap="true" backgroundColor="#FFFFFF" backgroundAlpha="1">
</mx:TextArea>
Basically, this allows for a small 'popup' when the user edits a cell in the datagrid, allowing for more space to type. The problem that I am having is that the datagrid gridlines show through the itemeditor - i.e. the itemeditor is transparent. Is there any way that I can force it to be opaque?
Following is the sample code. While I start editing either in optionId column or option column, the other rows of the same column are also get affected and reflecting the same value. But when I am editing in other columns it is working fine... Don't know the reason.

I have a DropDownList inside the itemEditor of my DataGrid. There are enough items in the DropDownList to justify scrollbars. You can see the scrollbars, and the mousewheel works fine. If you move the mouse over the scrollbars, they'll change appearance fine (mouseover is working). If you click on them, the DropDownList closes as if you'd clicked elsewhere in the data grid.
I've been experimenting with custom skins hoping to find a way to trap the mouse event, but have been unsuccessful.
FWIW, this is Flex4, as an AIR app.

If you have two text areas with different styles (fontFamily, weight, color etc) and you copy text from one to the other it also copies the style from the originating text area. Is there any slick way to prevent that?
Here is a sample of code that will illustrate the problem. Type some text in the top box and some text in the bottom, then copy some characters from the top box to the bottom. I'm not using htmltext.[code]...
I hope I would not waste your time too much. I am going to publish my Adobe Flex library to sell in commercial, but I don't need anyone can open my SWC file and study the code in there. I see Adobe Flex library can prevent this activity. How could I do this too?

View 3 RepliesI'm finding that in flash (10.x at least) and ie (7, 8, 9) that if I try to load an image url that contains escaped utf-8 characters (p%C3%83%C2%A5) that the characters get decoded before it makes the url request, even if I double or triple encode them. Is there any way to prevent this so the url (with escapes) the way I want it is actually what is requested?
The problem its causing is we give a http status of 301 on utf-8 decoded url requests to the encoded url which flash then tries to request (but ie decodes it again) and I get stuck in an infinite loop because of the 301 + ie auto-decoding.
EDIT, adding code sample:
var url:URLRequest = new URLRequest('http://mydomain.com/p%C3%A5.jpg');
var loader:Loader = new Loader();
loader.load(url);
Now I want the request to go over the line as [URL] (and it does in other browsers), but in IE it goes over the line as [URL]
EDIT: replacing % with %25 (double encoding the %) but that didn't work, it just caused this request to go over the wire: [URL]

I think there is a simple solution to this question, just not simple enough for me to find it.Question:How do you constrain a TitleWindow in Flex 3 from being dragged off the screen/stage? Is there a way to restrict the TitleWindow to the viewing area? Example: Let's say I have an application that take 100% of the screen. Next, I create a TitleWindow via the PopUpManager. I can then proceed to click and hold (drag) that window off the screen, then release the mouse button. That window is now lost off-screen somewhere. Is there a way to keep the window from being dragged beyond the viewing area?

View 5 RepliesI've hit a very strange issue in adobe flex and I'm not sure how to solve it. I have a popup box that is called on creationComplete before startup of my main application.

However, when I try to access the email address from the label component called UserID.text in the application, it is always null even though it is visually present in the label box...It seems like it loses state somehow...so HOW in earth can I keep it from losing state? I need to access the label or some variable throughout the use of the application and everything I try always ends up in a null variable?The main part of the application that sets the label is here:

View 2 RepliesI am using Google AppEngine, in conjunction with PyAMF to provide RemoteObject support. In my Flex code I make several RemoteObject method calls at once which tends to batch the AMF Messages into a single HTTP request. Most of the time this is fine but AppEngine applies some strict per request limits (in this case I am hitting a DeadlineExceededError - max 30 seconds). A number of service methods are expected to take upwards of 10 seconds and if these are batched by the RemoteObject into 1 HTTP you see where this is going. Now you could say refactor your service calls and that is also going on but not really the question being asked here. Is there a way to prevent Flex RemoteObject from batching AMF requests for situations like this? I have done a fair amount of Googling on the subject and come up with bupkis. It seems to me that I would need to implement a custom version of mx.messaging.channels.AMFChannel or something of that nature, which seems waay too hardcore for a feature like this
