don't need stylesheet info like font size or face. Seems like your approach
may be exactly what I need.

And it appears the error *was* caused by having a column with a value for

Sorry to hear your posts get unanswered. I can only suggest a 'try'...did you

Hi Tom,
Since it apparently happens randomly, it seems it depends on the data that is
being passed from Flex to CF and that can vary depending on user input or

Can anyone explain how to setup mate with a Flex Unit 4 test? For example,
where do I create an instance of the event map?
I have
[Before]
[After]
[BeforeClass]
[AfterClass]
methods
Would it be something like this:
public function setup():void {
var myMap:EventMap = new MainEventMap();
Original question:
Is there a recipe for sorting initially on a column which has a computed
value in it?
I put together the example below which works great. I'm not sure what's
triggering the error in the actual code I'm dealing with, but this example
convinces me it's time for some refactoring.
If you don't have too many items in the dataProvider, you could create a second
DataGrid, with the same DataProvider and itemRenderers, that does not have a
height set and is not visible. The second DataGrid would render all of the
items in the dataProvider, because the height isn't set. Then
I need to post the displayed data to a server, complete with formatting. The
dataProvider does not help much; I'd have to replicate the work that the

You should always specify a valid dataField.
If you have null data items or items that are dynamic and missing properties
you can hit this error.

Yes, look at the appinstall log. I don't recall exactly how to do that so

Hi Nick,
Yes, it is possible. What is the goal of the automation?
If you want just a clean build done automatically, the ANT build would
be a good option.
If you want to automate Flash Builder UI, you can develop an Eclipse
plugin that would do that. Or you can use Eclipse UI automation tool
Thanks for that. I'll try it.
How can I solve a lack of space in my temp directory exactly? I've heard of the

Sorry if this all sounds stupid. I'm just a flex student at the moment. Cheers
for your help so far.

Are you including any other files in the package?
I seem to remember that certain characters in their file names could

Thanks Alex,
I had gone around and around to get a certain module to unload and was unable
to determine the cause. Your article was very informative and my suspicion is
that an image loaded at runtime was at fault. But that really isn't the same
thing as compile-time embedded assets, is it?
Have you recently changed sign certificates? Had a similar problem when our

How about just exporting a Flex Builder Project Archive and including it in

You can mix them. What you need to do is make 2 ROs -- one tied to the secure

You can also build the the RO up in actionscript but I find it easier to use a
"standard" services-config.xml file. In our environment I can't change the file
so it's ea
one thing which can cause this is if the update.xml file and the air file
