I'm using the Cairngorm framework to dynamically add nodes to my
tree. I use a custom object I created that has public properties:
nodeid, nodename, and children.
Everything works fine when adding hard coded object nodes in
the "execute" function of my Command class. ex.
var _node:TreeNodeVO = new TreeNodeVO();
_node.nodeid = 1
_node.nodename = "Root";
_tree.addItem(_node);
The issue comes in where I make dynamic call to the server when the
user clicks on the "Root" node and the results come back into
the "result" function of my Command class. While debugging I noticed
that the "Root" node on the treeview must of fired its expand event
because the "Open" icon was shown. Once I added the new children
they did not up under the parent. I tried to call force an expand
call again like this
trData.expandItem(_treeNodeVO,_expand,false,true,null);
but that still didnt work. Once I closed the main parent node and
clicked on it again the children nodes "did" show.
So I have concluded that somewhere between the "execute" function
and server call the node expand event is fired before the "result"
function. My main question is what can I do so the children will be
seen? force and event to be fired? Call a method off the tree
itself? etc....
<mx:Tree labelField="nodename" id="tvModuleView" width="100%"
height="100%" showRoot="false"
itemOpen="treeModelViewHelper.addNodes(TreeNodeVO
(event.item),true)"
dataProvider="{ModelLocator.getInstance().treeViewModuleList}"
folderOpenIcon="@Embed
(source='/assets/images/treeicons/dsChild.gif')"
folderClosedIcon="@Embed
(source='/assets/images/treeicons/dsParent.gif')"
defaultLeafIcon="@Embed
(source='/assets/images/treeicons/dsRoot.gif')" />
Thanks
