IsUserInRole - NullPointerException

forums_noreply@adobe.com — Thu, 30 May 2013 16:55:38 GMT

What are some of the reasons why a call to the IsUserInRole function would throw a java.lang.NullPointerException error?

Sample code:

</cfif>

Thanks,

cfgrid (type=flash) - how to capture in-cell keystroke event?

forums_noreply@adobe.com — Thu, 08 Nov 2012 20:42:09 GMT

Yep, I'm maintaining a Flash type cfform that was authored a few years ago. The application is on CF9 now.

How can my application sense when a user has keypressed within a CFGRID cell?

I've introduced a change event listener to the cfgrid via the onchange tag attribute. The event fires when the mouse clicks within any cell.

But keyboard navigation or individual cell keystrokes to not trigger a change, even when traversing to another cell via Tab or Enter.

I've also tried using the keyDown event, but that is only triggered when navigating the overall grid. It does not fire when a cell has focus - the user is typing within it.

keyUp doesn't work either, nor does keypress, keydown, keyup or any of my other exhaustive deriviation attempts. I've tried to locate a complete list of AS 2.0 event names, but have had no luck, even within Adobe's own pdf docs. If anyone has an example from their own personal museam, I'd love to see it.

Did I mention that this is a Flash cfform? Thought so...

Formatter rounds - the same number - two different ways?

forums_noreply@adobe.com — Wed, 31 Aug 2011 03:38:52 GMT

See and/or run the 4.01 code below. Although the resulting number is the same, the formatted output is:

8485.50

8485.51

Please advise what revision I should make so that I get 8485.51 in both cases.

Thankew!!!

Can not change restrict property of TextInput via ActionScript

forums_noreply@adobe.com — Wed, 13 Jul 2011 20:17:35 GMT

Please tell me why this does not work, or suggest a workaround.

This debug example should change the TextInput to allow a dash when the box is checked, yes?

                }
                else {

Each of the restrict strings will work when applied directly as a mxml attribute.

Remotely populated toolTip: How can dataTipFunction call for data?

forums_noreply@adobe.com — Wed, 29 Jun 2011 23:16:52 GMT

The function you specify with dataTipFunction attribute must accept an Object (typically a data row) and return a String (for the toolTip). This implies that the work must be performed within the confines of a single function.

But what if you want to make a RO call to the server and fetch the latest tooltip content from the server - right at the mouse over event?

That normally involves two functions: one to make the call and another to process the result event. Can't fit those two inside a simple function now, can I?

If my desired outcome is actually possible, can someone provide a bare conceptual layout of such an entity would be constructed?

How to prevent deleted ghost data from returning to my datagrid?

forums_noreply@adobe.com — Mon, 31 Jan 2011 22:40:37 GMT

I have a mx:DataGrid which is populated from an ArrayCollection - and has s:DropDownList and mx:Image types as custom item renderers within.

When I delete a row via removeItemAt() - I follow up with validateNow() on the datagrid. All is well.

The problem comes from adding a new row therafter. The custom item renderers on certain new rows will display data as if from the deleted item. But when I examine both the ArrayCollection and the DataGrid's dataprovider (via a breakpoint), there is nothing there to match what's being displayed in the row by the custom renderer. The data looks clean, but the renderer's "dirty".

How do I delete a row (which contains custom item renderers) from a datagrid and insure that it stays dead (a subsequent new row creation does not contain these renderer relics)? I've tried validateNow(), invalidateList(), invalidateDisplayList(), even setting the dataprovider to null and back again.

It's as though Flex 4 is dredging the actual renderer back from the dead, already set with g-g-g-g-ghost data!!

How to get session vars of another or any current user

forums_noreply@adobe.com — Fri, 21 May 2010 05:38:18 GMT

We all should know that the syntax session.varname will get or set a session variable for the one user currently making the request.

But can we write a method to get the session structure for ANY given user, when provided with a valid identifier like sessionID?

Don't everybody all yell at once now.

Contructing an Object with dynamic property names?

forums_noreply@adobe.com — Fri, 30 Jan 2009 04:32:30 GMT

So the live docs for "Object" construction reads like this:
var obj:Object = {a:"foo", b:"bar"}

But what if I need to build an Object using run-time property names, like this:
var obj:Object = {DYNAMICNAME1:"foo", DYNAMICNAME2:"bar"}

(where DYNAMICNAME1 = "Fred" and DYNAMICNAME2 = "Barney", for example)

Since a and b are not strings nor variables, either it can't be done or I can't understand how to do it.

Can someone give me a nudge in the right direction please?

premature end of file compiler message in Flex Builder

forums_noreply@adobe.com — Fri, 23 Jan 2009 21:05:59 GMT

Quite often, when I save a mxml file and the project builds automatically, the compiler will halt with a "premature end of file" error message.

As an experiment, I've caused this error via a "false modification" (in which I take a perfectly good mxml file, added a space, deleted the space, then saved the file).

In addition, when I compile the application using "Project | Clean", the error goes away every time.

What gives? Anyone else been through this?

P.S. thanks in advance for the "launch the app with -clean" idea (from the similarly listed bug), but I've already tried that.

works in Flex 2 - null object reference in Flex 3

forums_noreply@adobe.com — Thu, 14 Feb 2008 00:55:26 GMT

I've reproduced from scratch a development project in my Flex 3 beta 3 plug in, creating each file within the Flex 3 environment. The only short cut I took was to copy the actual code from my eight Flex 2 project files (one main mxml, 4 custom mxml renderers and three included action script files) and paste them into the blank ones I created under the new Flex 3 project.
When I run debug on the compiled Flex 3 swf; it throws an error that it didn't throw in Flex 2:
Error #1009: Cannot access a property or method of a null object reference. I was getting the length of an Array which is populated as a result of a WebService result (same as I've always done. Did I mention it's the same code?).
Furthermore, when I trap for this null then another whole swath of previously absent null references start to appear elsewhere, as though entire blocks of variables are no longer in the scope. Compilation issue?
I don't want to post pages of source code to possibly duplicate a known issue/bug/blog/thread. Does this result look like something you've seen addressed before (ie "worked in Flex 2, broke in Flex 3"), and - if so - where?
Update: No change in the code, but it worked once when I compiled it yesterday. Whoops, now it's broke again...
