dhtmlxTree Error type: Datastracture XML refers to not exi

Hello
I am having a problem using dhtmlxTree using data processor and data connector.
I get
Error type: Datastracture
XML refers to not existing parent

the xml connector produces is :



any help???

Which code you are using on client side. Such error occurs when incoming xml can’t be linked to existing tree elements.
While initialization tree, you have a code similar to the next

var tree = new dhtmlXTreeObject(some_object,“100%”, “100%”, 0);

the last parameter is ID of virtual root, which must be equal to the tree@id attribute in XML response.
