Hi,

I have created a tab in the Incident Workspace.  Inserted a Browser Control in the tab that points to a php page.  The php page has some php and Java script as well as some HTML.

I am reading some incident field values from the javascript/passing through the URL.  The User clicks on browser control tab, comes back to the Incident Summary Tab and updates the field values.  When the user clicks on the browser control tab again the updated values are not passed to the php page and the javascript code is not executed again but reading from cache.
