Editing Datasource of TreeGrid

Smart GWT Technical Q&A
1

Hi Guys,

I want to write an application which should open an existing XML file and load it into a TreeGrid.
I already have a TreeGrid which shows the content of a XML file which i stored in /data/test.data.xml.
But when i edit something in the TreeGrid the modifications are not saved to the xml File.

I have already tried to set OperationBindings for update like
new OperationBinding(DSOperationType.UPDATE, “data/test.data.xml”);

I have exactly the same problems.
I think that it is possible in smart GWT EE but it is not free.

This is not version specific, EE does not implement storage in XML files. That’s a test data file used by the Admin Console.
