Re: [flexcoders] Re: Is there a way to find an object if you know the name

[Marlon Moyer]

believe me, I've tried to attack this problem from a number of ways :)here's the quick description:My form design:Policy 1: accordion  Division 1: accordion    State 1: Tab      VBox
        Code 1: text input        Code 2: text input        Code 3: text input      Add Code: button      /VBox    State 2: Tab      VBox        Code 1: text input        Code 2: text input
      /Vbox    State 3: Tab  Division 2: accordion    State 1: tab    State 2: tab .etcThis is directly created from an XML doc read in the e4x format.  I've got the code working so that I'm able to add code via the button in the state tab. 
When debugging, I can see that the vbox's repeater item now reflects the changed XML, but the screen is not redrawn to reflect the new line for the code. My first plan was to just reset the dataProvider for the the entire form.  Bad idea, it causes the whole form to redraw and loses the current location within the form.
My next plan was to reference the vbox's repeater and reset it's dataProvider to be mine XML snippet.  So far no go :(  My next plan is to try to figure out how to create a data model for a dynamic xml document.  I figure this is going to be just as successful as the first two plans. :)

Yes, you should probably back up a little and think about what you are trying to do.
 Directly accessing elements of data-driven controls is usually a bad idea, mainly because the controls re-use the visual elements when you scroll.

 ..one more note.. You may want to also check out "Referencing repeated child components" in the help docs, which is specifically about components within a
 repeater. --Mike --- In flexcoders@yahoogroups.com
