Re: ActionForm 'reset' method being called when JSP is rendered

[Paul Harrison]

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....

In Struts 1.0.2 and later, reset is called by the html:form tag *if* 
the ActionForm is being instantiated at that time. The scope shouldn't 
matter.

Also remember that the html:form tag is looking at the Action to which 
it submits, which may not be "Action 1". If these are the same Action, 
or share the same formbean under the same attribute, then the 
ActionForm should already exist, and reset should not be called.

I'm seeing some odd behaviour with one of my actions.  If anyone can

this I'd sure appreciate it....

Here's what I've got - in struts-config I have an ActionForm that is 
shared
by two Actions.  The ActionForm is created in session scope by the first
action, and referenced by the second Action (also in session).  
Tracing the
calls to 'reset' and 'validate' I see the following:

    JSP is displayed  -> html form is submitted -> 'reset' is called ->
'validate' is called -> Action 1 is performed -> forward to next JSP ->
'reset' is called -> JSP is displayed
    
/\/\/\/\/\/\/\ !

My understanding is that 'reset' should not be called again until the 
form
on the second JSP is submitted.  Have I completely mis-understood how 
this
works?  Or is it something due to the ActionForm being created in 
session
scope?

TIA!
