[flexcoders] Re: Passing parameter to component

[Cathal]

Actually you are correct, it is not assigned untill later. The reason
my little test with the label didn't work was because I forgot the
[Bindable] tag in the actionscript.

I've tried to just display the contents of this variable to test it,
but nothing gets printed to the screen.

code inside the component:





If I replace the selectedItem code with a string "Hello", this prints
to the screen correctly.

[flexcoders] Passing parameter to component

[Cathal]

Hi,

I'm trying to pass the selected item on a combo box in one component
to another component.

If i bind it to a label it works fine,

code: 


but passing it into another component it doesn't work.

code:



While in debugging mode strProjectName seems to be null, so it doesn't
see to be assigned anything.

Any suggestions?

this needs an event first, no? Any suggestions?

Thanks,
Cathal

[flexcoders] Populate label with item from combobox

[Cathal]

Hi,

I have a combobox which is populate by an XML file and works fine.

code:
 

Once, the combo box is changed it fills a label with the value selected.

code:
private function setCompanyName(evt:Event):void
{
lblCompanyName.text = evt.currentTarget.selectedItem.projectname;
}

The problem is what if only one item exists in the combobox. There
cannot be any change. I want the label to be filled by default item in
the combobox and also on any chnage, I've tryed with selectedItem and
selectedIndex but with no luck. Any suggestions is appreciated.

Kind Regards,
Cathal O'Brien
