Treepanel with row editing issues.

[Edd]

I'm implementing the row editing for my treepanel, but it isn't working as I expected, sometimes the update action distorts my treepanel and sometimes doesn't. Also I'm having problems with the sync function:

onEdited:function(){
        console.log(this.getStore().getUpdatedRecords().length);
        this.getStore().sync();
    }

The first time I update a record I get on the console:
1
And the record is updated in the database.
If I perform another update I expect the same results but, instead I get:
2
and an Internal Server Error :S

Any Ideas?

Have you checked out the request to see if it is valid?

[Edd]

Yes, I checked, but it is not valid because it expects just one record, but I'm sending two.
According to the docs:

getUpdatedRecords( ) :
Returns all Model instances that have been updated in the Store but not yet synchronized with the Proxy


So I don't know if the sync function is working, I can see the update in my database :S
