Wanted: Pre-selected tree node in Flash forms CFTREE

by kai on 07/09/2005

I'm going mad with this. Do you know this situation - you wanna do something very simple and it turns out to be the most ugly and head-banging issue for a while...

For me it's how to preselect a tree node in a Flash forms CFTREE. It doesn't seem to be possible with the "offical" tag attributes, but who cares. The Flash forms offer so many ways to tweak their behaviour, but I really got bloodily stucked this time for nearly two days now - args! And it's not just me, there's someone else working on it and we just can't make it working properly.

While playing with that, I learned a lot about the CFTREE and how it compiles down to MXML, but this particular issue nags on me.

Any idea is welcome - help!!! ;)

Ok This should work, I had the same problem... Selects by attribute id on myTree With only the length constant to work on this function successfully selects a node by attribute and displays it in the tree list. With all other branches collapsed... function selectNodeWithID(id) { //Open All Nodes for (i=0;itheNode;i--) { myTree.setIsOpen(myTree.getNodeDisplayedAt(i), false); } //Get difference from last node lastN = myTree.length - theNode; //Close all Nodes above Parent Node for (i=(pIndex-1);i>=0;i--) { myTree.setIsOpen(myTree.getNodeDisplayedAt(i), false); } //Set index from last Node lastN = myTree.length - lastN - 1; //Display Selected Node myTree.firstVisibleNode = myTree.getNodeDisplayedAt(lastN); } Regards Johan

I, too, spent a long time with this. My final solution was to add an additional text field, and use a binding to display the preselected item there. Additionally, I open the branches tree, so that the branch's (and only that branch and its ancestors) preselected item is already visible.

Hi, I'm working with a CFTREE control on a flas form at the moment. I have encountered some problems populating the tree with child items(sub menus). May be I can throw light if you haven't got any solution to your problem. But what do you mean by pre-selected node tree?
