Hi
The WHEN-TREE-NODE-SELECTED trigger fires twice, it fires when selecting the node and when deselcting the node.
add the below if condition in your trigger. This will make your code to be executed only when you select the node and not when you deselect it.
IF :SYSTEM.TRIGGER_NODE_SELECTED = 'TRUE' THEN
  ...    --Your execution code
END IF;If your item name is the node's label itself you can easily do this:
IF :SYSTEM.TRIGGER_NODE_SELECTED = 'TRUE' THEN
  :your_block.your_item  := FTREE.GET_TREE_NODE_PROPERTY(HTREE$, :SYSTEM.TRIGGER_NODE, FTREE.NODE_LABEL);
END IF;Hope this helps...
