Hi John,
I can pass a session from a SIListView to a dialog or a new window that has a qSIListform on it. On the qSIListView aI have a field defined as LinkTo and the session defined.
Regarding the httpParameter, only the ID can be passed correctly. All other httpParameters you include in the URL will be ignored.
Please contact customer support so I can create a work item to address this issue.
Regarding the size of the Dialog window there is no such an option to customize it using ezEdit.
