actionform reset()

[Sean Giles <Se...@trx.com>]

I'm very confused by the behavior of the reset() method.  

We populate a page from an action form with request scope which works fine,
however unless a property is actually used on the form it does not get
repopulated after the reset() method.  

for example:
If I don't use <html:text property="address1"/> or <html:hidden
property="address"/> the reset() sets this property to null it will not be
re-populated.  System.out shows the property has a value right before the
reset method?  

Is this by design or am I doing something in correctly?  If it is by design
how are multi-page forms supposed to be handled that only display a subset
of an actionform object?


Thanks
Sean

The reset() method is called immediately before the bean is populated with
the parameters from a request. For multi-page forms, you typically do not
want your reset() method to zap everything. In this case, you will most
likely use a hidden field to identify the page being submitted, and base
your reset() implementation on the value of that hidden field.

Hope this helps.
