Re: [flexcoders] Issue with Tree in Flex
Thank you steve, I'm using expandTree(); to get the first node expanded on creation of the tree. my requirement is to keep the first node open after creation of the tree, there after it will be handled by the user. thanks and Regards DB valdhor-3 wrote: DB I tried your code and saw the exact issue you describe.

RE: [flexcoders] Issue with Tree in Flex
Ok, but do not do that in the labelFunction. Do it after assigning the dataProvider, probably delayed with callLater().

RE: Re: [flexcoders] Issue with Tree in Flex
Hi Tracy, yes, you are right, I 've removed it and calling the expandTree from a changewatcher, the function is fine and working as per requirement. i don't see any issues in tree now. Thanks for all giving excellent advices regards DB Tracy Spratt wrote: Yes, a label function should only build the label string, not do anything else, especially manipulate the visual elements of the control it is being used to render. A label function gets called for every visible node in the tree, which changes when you scroll, open a node, etc. No wonder you confused the poor tree! What is the goal of that line?

[flexcoders] Issue with Tree in Flex
Hi flex experts,
I'm using tree for a requirement, when we try to open more number of nodes
and browse thru the the tree,
these are the issues that occur.
1) Tree View goes either Blank or filled with one node name.
2) It hides few nodes.
In other words, On expanding more nodes the tree view goes either blank or
hides few nodes (sometimes the single node name appears through out the tree
view).
The following is a sample tree code that i'm trying to use. You can copy
paste and try executing this.
Thanks in Advance.
Regards
