I am creating a tree that I am dynamically loading the children for. Each list of children for a node represents a web service call that I must make, so I don't know how many children are present until the children are loaded. I was trying to lazy load these guys based on when they are asked for (so I put the loading code in the getChildren() method).
To make sure the '+' sign was drawn, I returned '1' as the child count if the children were not loaded. I made it so toggling expansion is done via AJAX. The problem occurs if I exand a node with no children. Example (before): - A + B + C I click on the + for 'B' which actually has no children on the server and I get: - A - B - B - B - B The grid lines get lost 'in space' after B, and C is never rendered. If I refresh the page, the tree is accurate: -A -B +C It just really doesn't like me reporting '1' as the child count and then returning 0 children later. Is there a way I can get it to accept this fake node count and not blow up upon re-render? I would rather not have to pre-pull one more level from the server if I don't have to (in this case, I would have to load B and C which would be 2 web service calls, so depending on the number of children, that could end up being several web service calls and not good for performance). Thanks, Andrew
