is it possible to show parameterGroup after installation but before final page? I would like to put it e.g. into postInstallationActionList (but i got an error, that it cannot be there).
My goal is to show user dialog with username and password and then do httpPost. If i show parameterGroup before installation, i cannot store result of the httpPost in the install dir, because it doesn't exist yet.
Thank you. Roman
