setChildren() takes an XMLList, not an XMLListCollection. Fix that
first.

 

Then, in handleGetChildren(), after the above call,
trace(accountsData.toXMLString()) to make sure you are building the xml
you expect.

The tree defenition:

mx:Tree id=accountTree height=100% width=100% 
dataProvider={accountsData} labelField=@name 
iconFunction=treeIcon itemClick=onItemClicked(event); 
/mx:Tree

Upon loading I'm calling this fuction that works great:

private function handleGetAccounts(result:XML): Boolean 
{
accountsData = new XMLListCollection(result.act);
return true; 
}

Upon clicking on an item I'm calling this function which doesn't work

private function handleGetChildren(result:XML): Boolean 
{
if (accountTree.selectedItem != null) 
{ 
accountTree.selectedItem.setChildren(new 
XMLListCollection(result.act))

accountTree.expandItem(accountTree.selectedItem,true,true);
}
return true; 
}

*** The handle messages are being called after the async call of 
HTTPSerivce has return

 

RE: [flexcoders] Re: Treeview - On demand updating of child nodes.

[Tracy Spratt]

Actually the doc is incorrect there. The XML api DOES dispatch the
necessary events to update the tree.

 

And if you are seeing the raw xml node then clearly this is not your
issue.

 

Post a bit of the xml, and the Tree tag declaration.

Thanks, but that is not the case... I'm using an attribute by the 
name of name.

However I did find this link :

http://livedocs.adobe.com/flex/201/html/wwhelp/wwhimpl/common/html/ww 
help.htm?
context=LiveDocs_Book_Partsfile=about_dataproviders_057_16.html

And in it there is this remark:
Remember that the Tree will not, by default, reflect dynamic 
changes to the XML object. 

so how can i change the default???

 The child nodes you add must have the attribute that you are using

 the label. Or use a labelFunction(). Seeing the raw data usually

 the tree does not know what to use for the label.

 Hi, 
 
 I'm trying to update a tree upon an on click event (so that when a 
 user clicks on a node it access the server and fetch the child 
nodes). 
 My problem is that when expanding the node I see the raw XML.. 
does 
 any one knows how to reflect the changes?
 
 Thanks,
 Yoni.
