[4.2] - Opening a workflow action page from a portal page bu

Hello,

I have a workflow action that creates a new record (obj1) using the existing records (obj2) details. This works fine in rollbase, however, I am trying to open that page when a user clicks on a button on a portal. The URL of the workflow action looks like this:

https://rollbase.com/prod1/m/main.jsp?id=5172962&relatedId=5172962&relatedObjDefId=15150&pageId=21272&actionId=16177&destId=17233&returnId=5172962

Is there a way I can get some of those url parameter values in a portal page?

For E.g.: actionId, destId, relatedObjDefId.. etc

Cheers.

Iram
