Wanted: Pre-selected tree node in Flash forms CFTREE

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!!!

Sorry, could not find any...

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?

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.

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;i myTree.setIsOpen(myTree.getTreeNodeAt(i), true);
}
//Parent branch flag
pBranch = true;
//Parent branch Index
pIndex = 0;
treeLength = myTree.length;
for (i=0;i myNode = myTree.getNodeDisplayedAt(i);
//Assign Parent Branch
if ((myTree.getIsBranch(myNode)) && (pBranch)) {
pIndex = i;
}
//Search Node for attribute id -- Change to whatever attribute you want to search
if ((!myTree.getIsBranch(myNode)) && (id == myNode.attributes.id)) {
myTree.selectedNode = myTree.getNodeDisplayedAt(i);
theNode = i;
pBranch = false;
}
}

//Close All Lower Nodes
for (i=treeLength;i>theNode;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);
}
