Hi,

I'm truing to create my first JPA2DataSource.
I created a .ds.xml file and overrided fields in order to put there validators.

Fetch operation works fine.
add and update operation freezes application. I receive "Operation time out" after a while and the lisdGrid will not load up data again, even after closing and opening a browser. (I have connection pool set to 1).

when I try to update record as follows then it work and data get saved.

Code:

record=userGrid.getSelectedRecord();
record.setAttribute("active", false);
userGrid.updateData(record);

when I use value manager data are loaded into a dynamic form.

Code:

ListGridRecord record = userGrid.getSelectedRecord();
valuesManager.editRecord(record);

when try to save the call will never make it into the execute method

Code:

valuesManager.saveData(new DSCallback() {
	@Override
	public void execute(DSResponse response, Object rawData, DSRequest request) {
		destroy();//window
	}
});

I had to copy groovy-1.8.2.jar into a classpath because of class not found exception.

I don't know how to prepare a test csae for you since I would have to copy all my JPA entities and without a database it's pointless anyway.
At least, please find attached a relevant files.

This is probably related to your earlier questions about custom EntityManagers - code you're not showing is causing some kind of hang. There's nothing we can do with this information yet (no way to reproduce, and unlikely to be a bug) but let us know if you can produce runnable code that demonstrates a framework issue.

Hi,

I'm sorry for that. You were right, I drove my application into a dead lock.
I converted all my DMI's to use EMF instead and now I got it to work.

best regards,
Zdary
