jQuery Grid Plugin - jqGrid

Hi,

Im trying to use a treegrid (type nested) with autoloading. but I encouter some problems. 

At first i tried to resolve only the child elements of a selected node. But when i do this Only these elements are shown in the grid. So when i do this i cannot go back up the tree because the parent nodes are gone.

So i created a query witch returns the selected node and all the parents (and their neighbours (nodes with the same level) ) this almost works correct but because of the property isNodeLoaded i cannot re-open an node after opening another.

A fix could be to send all of the opend nodes to my php page and resolve all the data but i dont think this is the best way because the autoloading feature is to be able to load large lists and with this way the treedata keeps growing until its too big and the browser crashes.

What i prefer is my first method because this only fetched the nodes that i need so it should be appended to the grid instead of replaced.

is there someone who knows how to fix this?

Thanx in advanced

Tom
