Getting the parent node failed

Hello,

I developed new form with my 2 datasources that are also datasources on the form from which my new form is called.

So, main form has menu item that calls new form with the same datasources.

One datasource is parent and one is child.

When I save the data on my new form its ok and I dont get an error but when I click refresh (only the data refresh) I am getting Getting the parent node failed error and I am unable to debug it.

Any help?

Thanks in advance
