Anyone, please? I tried one more thing:
I reverted to using Tree instead of VirtualTree. Inside the custom widget TreeColumn, I replaced the child control addition code to be exactly the same as the Twitter example, by overrriding the _createChildControlImpl (the Twitter example does mention that this function takes care of not creating new objects if they already exist). But, no diference :-(. The createItem delegate function does get called and new objects are created at every data reload. I ran the Twitter code and there the createItem delegate is called only once and data reloads only refresh the labels. I am guessing that the Tree model does not do incremental updates and the List model does. With VirtualTree, I have the createItem issue resolved (the custom widgets are created only once and only their labels are refreshed at data reload). But, setOpen(true) does not work :-(. So, the tree is always loaded in a collapsed state. Data reloads always cause the tree to be collapsed.
