In my rails app that I am porting to grails whenever an unexpected error occurs I intercept the error automatically and display a form to the user informing them that an error has occured and asking them for further information. Meanwhile, as the form is rendered I write the stack trace and other information about who was logged in to a database table. Then if the form is submitted I add that information to the error report.

I cannot tell from the exceptionHandler documentation and BootStrap examples whether that will allow me to grab all the information including various session and request parameters and then stuff them into a database and then post a form.

Any thoughts?
