Error while switching between renderers in mx:Tree

["Patil, Virat" <vi...@capgemini.com>]

Hello

I have following code trying to switch between renderers at runtime. And Reassign data . I have tried using CallLater method to achieve it  Can somebody suggest a solution.

private function switchRenders():void{
                        if(multiSelect.selected)
                              listTree.itemRenderer = new ClassFactory(renderers.CheckBoxTreeItemRenderer);
                        else
                              listTree.itemRenderer = new ClassFactory(mx.controls.treeClasses.TreeItemRenderer);

}
Getting Following error:


TypeError: Error #1010: A term is undefined and has no properties.

Re: Error while switching between renderers in mx:Tree

Define two states in your application, and either:

1. Define two mx:Trees, one with each item renderer, with includeIn for
each Tree set to each state, and just switch between states :)
2. Or just define one Tree, with itemRenderer.state1=itemRendererClass1,
and itemRenderer.state2=itemRendererClass2

I personally would go for option 1, since I have also had troubles
switching itemRenderers on execution time. Overhead is not a problem, since
the includeIn attrib is more or less the way to tell Flex "treat all this
as a comment unless you are in this state"  :)
