The tree icons are not displayed when we use enableSmartRendering property along with setXMLAutoLoadingBehaviour and setXMLAutoLoading properties for loading child items for first time, once we expand the the tree, the images gets displayed. Can you help me out for this issue. I have created a demo and attached it to this topic to reproduce the issue.
Smart rendering and dynamic loading are not compatible. You can try treeGrid to use these 2 modes together
