I have a view AddActivityView.mxml and in that view is code to display
a list of activies.
I recently added code to hide (isvisible = false) some of the nodes of
the Tree generated by data coming into this view.
The code looks like this...
private function
filterInvisibleNode(item:Object):Boolean {
if( item != null && [EMAIL PROTECTED] == 1){
return true;
} else {
return false;
}
}
private function get
filteredCollection():XMLListCollection {
var col:XMLListCollection = new
XMLListCollection(
MyModel.getInstance().activities );
//Alert.show(col.toXMLString());
col.filterFunction = filterInvisibleNode;
col.refresh();
return col;
}
And the Tree :
<mx:Tree height="100%" id="actTree"
width="100%"
dataProvider="{ filteredCollection }"
showRoot="false"
labelField="@label"
borderStyle="none"
dragEnabled="true"
dragMoveEnabled="false"
itemRenderer="com.renderers.ActivityTreeRenderer"
toolTip="" />
This seems to work fine for hiding the nodes. However what I'm running
into it this:
the Activities reorder themselves when I click on 1.
For example on load the activies show
Work
Work + 60
Work + 45
Work + 30
Training
If I click on "Work" it goes to the forth item in the list and looks like
Work + 60
Work + 45
Work + 30
Work
Training
Then if I click on Training, that goes to the 4th item in the list..
Work + 60
Work + 45
Work + 30
Training
Work
If I click on Work + 45 it too goes to the 4th item in the list
Work + 60
Work + 30
Training
Work + 45
Work
This is not ideal behavior heh..
What would cause something like this to happen when I click on it?
MyModel.getInstance().activities is populated during the LoginCommand
onResult and looks like
if (MyModel.getInstance().employee.isEditor())
{
var meEvt:CairngormEvent = new
CairngormEvent(MyController.EVENT_GETACTIVITIES);
CairngormEventDispatcher.getInstance().dispatchEvent(meEvt);
}
Please help me out here! Thanks again!
