Subject Re: ActionForm 'reset' method being called when JSP is rendered
Date Thu, 19 Jun 2003 15:43:07 GMT
I am writing an application with a series of "wizard" type pages, so I 
thought that I would use one big ActionForm in session scope and each 
page add extra information to it - however this did not work as reset 
was being called at each page invocation - I am interested to hear that 
reset should only be called at instantiation time, because I believe 
that in 1.1 RC2 it is being called more often  than that - I can did out 
the old verision of the code to have a look at the exact circumstances 
if necessary....
