It's probably the maximum that is causing the loop. You could just try commenting that out and see if it solves the stack overflow error. If so then you'll know that Kit was right in that setting the maximum in turn calls set data.
You might try overriding the set maximum function then too and control it that way to avoid having it caught in the loop. -Marty On Sun, Sep 12, 2010 at 10:56 PM, Laurence MacNeill <[email protected]>wrote: > And why don't my other custom Item Renderers get stuck in the same loop? > I'm referencing 'data' in them as well -- shouldn't their get/set data > functions get caught in the same infinite loop? > > L. > > > > On Sun, Sep 12, 2010 at 10:53 PM, Laurence MacNeill < > [email protected]> wrote: > >> Yeah, it seems that way to me too...
