Node gets invalidated

In my WD-application I populate a Value Node with new entrys when a user clicks on the AddToList-Button.

I use the addElementMethod of the Node-Object. This works for a couple of times but then the Node is invalidated somehow and the application hangs.

In the onActionAdd-Method I use

IPSPListElement element;

element = wdContext.createPSPListElement();

element.set....

wdContext.nodePSPList().addElement(element);

My ContextNode has just a flat structure with about 5 attributes (no child nodes).

I understood that the supplyFunction is only needed when we deal with hierarchical node-structures?

What could be the reason for this strange behaviour?

Regards

Michael
