ListGrid + filterEditor + hidden criteria

[pH4Lk0n]

Hi,
Is it possible to send with default filter editor any additional criteria?
I'm trying to set up TreeGrid as master grid and ListGrid as detailed grid.
So I execute default method:
listGrid.fetchRelatedData(record, dataSource);
And this works fine but then filter editor stopped working.
Is it another way to add additional criteria to be sent?
Field information i want to add is hidden in ListGrid so it won't conflict with filter editor.
I tried to send this criteria directly to DataSource and then fetch from ListGrid but it doesn't solved my problem.
Do you have any ideas?
Thanks

We're getting "works for me" with a similar sample. Can you put together a standalone, minimal test case?

Sorry but don't know what exactly do you mean. A JUnit test case?
I'm using PHP as server and adapted RestDataSource so I don't know if that could be useful. Or I misunderstood.
