violation

I started to use CheckThreadViolationRepaintManager to detect EDT violations.

It complains about:

partner = getParameter("partner",generatePartnerSelectionPanel(),Design.partnerSelectionDuration);

Because it does not like generatePartnerSelectionPanel() because it does not like JPanel panel = new JPanel(); in this method. But I cannot find out why there should be a problem around that.

In more details, generatePartnerSelectionPanel() generates a JPanel (I do it not in the EDT) but then, in the getParameter I add the JPanel to the main JFrame and I do it in the EDT (using invokeLater).

So, why there should be a problem?
