ID GENERATOR add ons for VAADIN FRAMEWORK 6

hi .
is there any purchasable/free add-on of id generator using for test vaadin 6 application by JMETER?

There is no such thing done for Vaadin 6.

There is DiagnosticServlet add-on for Vaadin 7

It would require some study how to back port this add-on for Vaadin 6.
