[flexcoders] Re: Passing parameter to component

[Cathal]

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:
mx:Script
![CDATA[   
public var strProjectName:String;
]]
/mx:Script
mx:Label text={strProjectName} /

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

 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: 
 mx:Label text={headerComp.cbProject.selectedItem.projectname} /
 
 but passing it into another component it doesn't work.
 
 code:
 
 comp:home
 strProjectName={headerComp.cbProject.selectedItem.projectname} /
 
 While in debugging mode strProjectName seems to be null, so it doesn't
 see to be assigned anything.
 
 Any suggestions?

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.

[flexcoders] Populate label with item from combobox

[Cathal]

Hi,

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

code:
mx:ComboBox creationComplete=userProjects.send()
dataProvider={userProject} labelField=projectname
change=setCompanyName(event) width=313 /mx:ComboBox

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
