i have the following problem. I have created menu with several menu actions for MusterColumn UI Element. It means i have a tree and if i click on element of tree i can call some actions for each element-tree. I have already mapped ""nodeElemet" to perform correct event-handling for each element of a tree. But i don't know how i can disable or enable the actions by choosing an element.
For example if i choose menu of my root element only 3 action schould be enabled(Close menu, show diagram, show piecharrt), if i use the child of my root element only one action can be enabled(Close Menu) and the so on for the last level of the tree.
Could you help please?
