Method Detail
checkPageInformation
void checkPageInformation(String page, String scriptSessionId, String windowName)(Code)
Fill in the page details from the servlet request.

This method should be used by anything that parses a batch, and then allows either uses a WebContext or allows other things to use a WebContext.

Caution Following this call, the passed scriptSessionId may be wrong. scriptSessionIds can become invalid due to server re-start, a timeout, or a back-button.

It seems wrong to throw a security exception, because it could be totally innocent. So this method will create a new script session and insert a script into the script session so that the page becomes synced with the new ID at the earliest possible opportunity.
Parameters:
  page - The URL of the current page
Parameters:
  scriptSessionId - The session id passed in by the browser
Parameters:
  windowName - Reverse Ajax uses window.name to avoid 2 connection limit
