birt won't save data set, "the structure is invalid" error

Question

We're trying to update a BIRT report project after recreating a database. So I type the new query but when I move to the Parameters tab (or any tab), the error:

The structure is floating, and its handler is invalid!

pops up, and in the error log the following error is shown:

Problems occurred when invoking code from plug-in: "org.eclipse.jface".

Then after that nothing else works; the changes don't register (there's no asterisk near the library name in the tab), and I can't save anything.

Stack trace:

java.lang.RuntimeException: The structure is floating, and its handle is invalid!

I don't know what to search; all results I've come upon come from different errors. Starting with "-clean" doesn't work, recreating the BIRT report project doesn't work... Any nudge in the right direction would be help enough.

Answer 1

I got the same error, but performing below steps helped me out.(I am working on a table )

1. Delete the data sets
2. Select the table, under property editor tab, click on binding tab, check Data set and select none.
3. You should get a prompt asking if you wish to clear all existing data feild information, Click on 'yes'.

All the data bindings with references to the deleted data sets will now be cleared and voila... continue with your work. Let me know if this worked for you too.
