Use Application.application.unit instead
of _root. Use parseInt to get the number value of your parameter instead
of the String. For the opening do setIsOpen(unitNode, true, false, false)
to avoid the animation and then you might be able to get the node correctly. Matt From: Hello, All. I've searched through the email archives and haven't really
found anything exactly solving the problem I'm having... Basically, I have a
Tree that lists out an e-learning course, with each unit being the root nodes,
with their pages living inside of them. What I want is to pass in the query
string something like ?unit=1&page=1 in order to have the system pre-select
the unit and page you've chosen elsewhere to view. My first problem is that when referring to the variables as _root.unit
and _root.page (I'm a flash developer, cut me some slack!) I'm getting the
variables fine, except they're typed as String and when I add them together, I
get the number 11 (the string "1" concatenated with the string
"1" instead of the 1 being added to 1 to get 2). That's my first problem; I'm received query string variables typed
incorrectly. My second problem is that even if I skip this step and try and
force my tree to open the specified unit (which works), and THEN tell the Tree
to set the selectedNode to to the correct node index, it's just pre-selected
the root node at that index instead of the node nested in the open unit. Now,
when I debug this and actually click the correct node at the correct index, I
get back the index I'm setting the selectedNode to, so basically I assume that
the selectedNode is being set BEFORE I open the correct unit node, even though
I call it after a redraw() after I set the node open. My code is below: public function selectDefaultUnit(event){ if(!_root.unit){ _root.unit = 0; } if(!_root.page){ _root.page = 0; } var unitNode:Object =
event.target.getTreeNodeAt(_root.unit);
event.target.setIsOpen(unitNode,true,true,false); event.target.redraw(); // maybe this is
unnecessary, but it won't hurt, right? var pageIndex:Number = _root.unit +
_root.page; // this is the code that gets me the strings concatenated with
eachother var pageNode:Object =
event.target.getNodeDisplayedAt(3); // i'm setting 3 here by hand for debugging
purposes event.target.selectedNode = pageNode; debugObject(pageIndex,false);// my debug
method event.target.redraw(); // redraws to show
the selections. if i don't do this, the tree doesn't show something as being
selected until i mouseover it a few times } Thanks!!! ........................................................ Kevin Conboy Lead UI Engineer / Office Dullard SpireMedia® Inspired Technology. Inspired
