It sounds like you may not understand that item renderers are recycled, and do not even exist when non-visible.
What exactly do you mean by "initialize" the item renderer? They are components, and live the normal component lifecycle, including initialize and creationComplete events. "initialization" that is not dependent on the item node data can be done in handlers for those events. Any properties or behaviors that are dependent on the item node data must be manipulated through the set data, commitProperties, updateDisplayList and invalidation mechanisms. My bet is a "customer" checkbox IS dependent on the underlying data. It must get its value from the data and user interaction must be persisted in the data. If you already know all this sorry, I may be misunderstanding your question, otherwise I suggest that you find an existing item renderer to use as an example. There will be many available. Google Alex Harui itemRenderer.

Is there a way to do this? Somehow loop through the items in the tree dataprovider and select them all so the itemRenderers are all initialized? I tried tree.openItems and looping through and doing tree.expandItem (item, true) but that doesn't seem to init the itemRenderers.
