Pass parameter in EPCM.doNavigate

Hello!

I have JSPDynpage the button, that have OnClientClick:

addPosButton.setOnClientClick("EPCM.doNavigate('ROLES://portal_content/Webdynpro/java_local_add_lot_position_jwd_nrj_applications_AddLotPositionApplication', 1, 'width=400,height=500');");

It's open WebDynpro page in new window.

How can I pass parameters into opening WebDynpro page?
