It's returning null the first time I click an image however subsequent attempts traces a value (I assume because it is set then, just not when the app loads). how to recognize it when the app loads?
Is there any shortcut way to add an eventListener to something like a select event for NavigatorContent. I am aware I can add a listener for a change event on the ViewStack and identify the selected NavigatorContent through that handler.

I've read the flex language reference: [URL]. This property is true if execute() has been called and not all of the results have been returned from the database. However, I'm having trouble understanding what that means exactly. I keep receiving an error:
Error #3106: Property cannot be changed while SQLStatement.executing is true.
I've tried creating an event handler for SQLEvent.RESULT, my thinking was that's how the results would get returned from the database and therefore executing() would return false - didn't work. Does this mean i'm trying to change my SQLStatement variable too quickly? how long does the execute() function take?
The code in question:
private function fileProgress(p_evt:ProgressEvent):void {
var char:String;
var line:String = "";
var counter:int = 1;
sqlStatement = new SQLStatement();

Stream is a filestream. I'm trying to read a textfile and put every line into a new sqlite table row. I've also tried using sqlStatement.parameters as an alternative way to do my insert queries, but to no luck. that throws a different error:

I was trying to retrieve binary data over HTTP for my Flex application, and was running into some stumbling blocks. HTTPService did not seem to deal with binary data well, people said to use URLLoader. But URLLoader does not have the nice AsyncToken/IResponder interface that HTTPService provides.
So, I did some searching and could not find anyone extending URLLoader to provide this kind of functionality. I went ahead and took a stab at it myself: [URL].. Basically it wraps a URLLoader and an AsyncToken, and maps the COMPLETE, IO_ERROR, and SECURITY_ERROR events from URLLoader to results/faults that get raised on the AsyncToken.

I have flat data in my app which I will need to group, summarize, and count as I normally would with a sql query. For this project though, it must be done in the flex app. I need to figure out how to group my data by day or month using a datatime field in my Arraycollection, then appropriately count or summarize data in other fields. I've used Groupingcollections before, but only when binding to hierarchical controls (like AdvancedDataGrid and Tree), but I need a resulting ArrayCollection with the grouped and summarized data. Basically, I'm trying to access my AC like a sql table (GROUP BY MONTH(datetime), COUNT, COUNT(DISTINCT(), etc.) and I'm unsure how to do it.

this seems really simple but I haven't gotten this to work. I am building my app with grails on google app engine. This pretty much requires you to use JDO. I am making an HTTP call from flex to my app. The action that I am calling on the grails end looks like so
[Code]...
I have tried just returning "hello from grails" and that works just fine. I have alos tried the following return showInstanceList the JDO docs say the query.execute() returns a collection. Why I cant just return that to Flex I have no clue. after playing around with this some more I was able to get a result event back by have grails convert the object to JSON or XML wish I could just return a damn ArrayList.
Getter functions allow obj.meth syntax instead of obj.meth(), I'd like to create an anonymous one of these to return from another function. function get ():Object { } is invalid syntax. I don't suppose Flex offers an easy way to get this functionality, if it's even possible?
View 2 RepliesI've a AdvancedDataGridColumn which has both 'labelFunction' and 'dataTipFunction' defined.I want dataTipFunction to return the output of 'labelFunction' + someText.

I'm getting really annoyed by Flex. Is there a way to make it wait for an httpservice to get its data without having to use a timer?
At the moment my code looks like this:
protected function loginUser(event:MouseEvent):void
{
if(txtEmail.text == "" || txtPassword.text == "")
{
[Code].....
When I do user.login(), it sends a request with a HTTPservice from my external AS class. In the result event handler for this httpservice, I set a public variable to true or false, depending on whether the user's credentials are correctly in the DB.
I then use a getter to get that boolean value. However, without the timer, it always returns false because my code is faster than the event result handler. If that makes sense.
So I have to use a timer to stall my application for one second.. But seriously, that doesn't make sense to me. There has to be a better way, no?
