net.sf.tapestry.Request Cycle Exception: Unable to resolve expression

[Rahesh Kumar]

Hi all,


I am working on an application that uses tapestry , when an user leaves the screen idle for the long time , we are redirecting him to a login page once he submits the form this works fine, but when the user again enters his password to login to the system, he gets the exception like the one below , the applicable variable a boolean value to find from which place the contractor is working from. Can anyone please explain what are the causes of these type of errors?
