Initially when building the tree , just add a single child node to each first level of nodes u show You can mark this node as a "indicator node" or a "busy node" - this will allow the + sign to come up for the actual node. When u click on the + sign , representing the actual node , just remove the busy/ indicator node after all the actual children have been added ...(also just check if the indicator node is the only child - this way u will avoid another database hit for the second open click for the same node.)
