We've seen lots of questions on modules recently. I just presented on
Modules at the 360Flex conference where I tried to answer some of these
questions. Slides and examples are at http://blogs.adobe.com/aharui
I could be wrong, but I think you are trying to specify data for a
component in xml. The only way I know to do this is to specify a
property of type XML then assign it and pick it apart. Here's a mini-
example:
Test.MXML
alexButton
xmlData
The DataGrid has a labelFunction property that it inherits from its
base classes, but it does not use it. Instead each column has a
labelFunction property that you want to set.

The code snippet worked fine for me if the intervals property is an
array of strings. Is it possible you are initializing intervals from a
web service call? If so, you have a timing problem in that the
selected index was set long before the data arrived (actually it
thought it had zero rows
In the original post, I see that things are collapsing horizontally,
and in two of the three pictures I see a horizontal divider. My guess
is that there is a timing issue where the width of the divided box
comes up 0 at the time of the layout, then pops back to the right size
later, but does

If you load SWFs there is a timing issue where, once the SWF is loaded,
we wait one frame and then ask the
The main reason is isn't working is an issue of types. You are setting
the dataProvider to an array of XMLNodes.
So, go back and set the dataProvider on the result of the webservice,
then let's get the cells to display the right thing.
You have proven that it works if you set the dataProvider
Unfortunately, there's no built-in API for disabling a row.
There's no official API to get at individual rows either. You could
set an enabled property on a row using setPropertiesAt, then have a
custom cellRenderer look for it and disable itself.

You're not missing anything. There's a super-secret mouseDown
handler in the datagrid that is messing you up. Lots of folks have
tried various ways to workaround it and I think they've succeeded.
Last time we tried it, we subclassed the DataGrid and overrode its
onMouseDown method to see if
Yeah, looks like a bug. Don't see any obvious workarounds either.
One questions: Do you even want to allow de-selecting a row? It might
be possible to block that by overriding the onPress handlers in the
SelectableRows in the Tree.

There are some idiosyncracies when objects appear and disappear under
the mouse. In general, by listening to all mouse events (down, up,
over, out) you can see a pattern that you can look for (you may see an
over instead of a down for example).
In other situations, this can be remedied by not

Do you mean the tabs in the right half? They are done via actionscript-

The renderer will always be drawn at x=0. I'd probably just add a

The TextInput is kind enough to do a toString() on anything passed to
its .text property, which is great for Number and other things, but
is the root of your problem.
My advice, subclass TextInput and put the null check on the text
setter.

Deepa is correct, but that affects your .text property.
Unfortunately, there's no official way to do it. I'd subclass
TextArea and override the layoutChildren method to get the inner text
field to layout at the desired position.

The Tree needs a hierarchy of objects each of which implement
TreeDataProvider. That way, at each level in the tree we can ask the
current node for its children and other data.
Built-in Flash types like XMLNode don't support TreeDataProvider and

Your sample didn't have a call to inputField.move(), which should
reposition the inputfield.
You may have to override drawFocus() or adjustFocusRect() to get the
focus ring to look right.

Flex4Flash did not ship in 1.5 or we hid it in a legacy directory, I

Start commenting out portions of the app and see if you find a
subsection that is sucking up the memory.
Make sure you've optimized the number of layout containers used.
Should you be using a Grid instead of a network of VBox/HBox?
Are you using Repeaters? They can be memory hungry.
You'll probably have to provide more details about how the List is
being used, but in general, we don't promise that Flash V2 modules drop
into Flex.
One of the main issues is that Flex is entirely dynamic. It
instantiates all of the components on-the-fly. In Flash one can easily

One common problem is that the cellrenderer is only written to turn on
the checkbox and not to turn it off. Follow the setValue method in a
debugger to make sure.

FlashPaperLoader is not an out-of-the-box Flex Component. Where did

The Pulse themes have fixed-size panel headers that don't respond to
headerHeight, because it is a graphic (simple MovieClip or JPG) and
therefore doesn't support the resizing API we use. In Halo, the
panel header is a programmatic skin. You can see similar
implementations in the SampleTheme
ImageButton is definitely worth a look.
I don't know what you mean by accepts, but Button doesn't use the
backgroundImage style. It's visuals can only be changed via skinning
and ImageButton attempts to simply the skinning process. If it
doesn't do what you want, read up on skinning.

An empty Application tag should come in at about 128Kb. Not sure why

At any rate, starting from 128K, you'll hit your 150K limit really
quick. However, I encourage you to consider the following:

Most computer interactions use mouseUp instead of mouseDown. For
example, you can mouseDown on the reply button as you read this message

In Flex we use mouseOut instead of mouseDown/mouseMove to trigger drag

This is a fact-of-life of how security in loaded SWFs works.
Assets in subordinate SWFs are not available to the top-level SWF,
but the cursorManager only can work in the top-level SWF.
The easy workaround is to put a DividedBox in the top-level movie and

Well, if you are in no-source-code hell, then you have to hack your

If you know the internal structure of the loaded SWF, you can try to
find the place the loadVars is done and try to grab a load event on
it, or set a timer and check to see if the loadVars is complete.
