Hi,
After using the MessAdmin tool to investigate orbeon user sessions it seems as the server has a memory leak when the xxforms:set-session-attribute() function is referenced on a view.
Each time a view is loaded that contains references to xxforms:set-session-attribute() the size of the session attribute oxf.servlet.session-listeners will increase. It seems as though new listeners are added each time the page is reloaded.
The problem can be reproduced using the simple page below (try reloading it a couple of times):
<head>
<xforms:model id="main-model">
<xforms:instance id="test-instance">
<test />
</xforms:instance>
</xforms:model>
</head>
<body>
<xforms:trigger>
<xforms:label>press</xforms:label>
<xforms:action ev:event="DOMActivate" >
<xforms:insert context="." origin="xxforms:set-session-attribute('test-application', forms:instance('test-instance'))" />
</xforms:action>
</xforms:trigger>
</body>
This simple page increases the session size with 1.6 KB for each request. If the model contains more instances the size will increase even more. For our application the oxf.servlet.session-listeners attribute increases 30 KB for each request.
