Basically, you need 2 actions, one to populate the form and one to
change the personal data.
Or at least two action mappings, if you want to use automatic
validation. If you're happy to invoke validation manually, you can get
by with just one action and one mapping.
This is EXACTLY what I like to AVOID! With this concept I have to write
dozends of useless action classes!
Nope, with that approach you would simply *seperate* your one action
class into two classes which each encapsulate one branch or your if
statement below -- i.e. an action that does 'Populate the form' and one
that does 'Perform update operation'.
If you don't like having two separate classes, there are various options
for combining them, including the various flavours of dispatch action
and the approach you illustrate below.
In my Action class I did:
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
{
ActionForward af = null;
......
String operation = request.getParameter("operation");
.....
if (operation != null &&
operation.compareToIgnoreCase("update") == 0)
{
..... Perform update operation here
}
else // showData
{
.... Populate form here
}
return (new ActionForward("/showPersonalData.do"));
}
The surprising thing (at least for me...) is, that when running in the
debugger, execute method is NEVER called (does not stop at any
breakpoint) !!!
Do you have validate="true" on your action mapping? If validate is set
to true, the framework will perform validation for you automatically
before invoking the action. Hence, you need to either a) have two action
mappings in your config (note: two mappings, not necessarily two action
classes), one with validate=false and operation set to null and one with
validate=true and operation set to whatever; or b) using a single action
mapping, set validate=false and call validate() manually as appropriate.
Is there no more intelligent way then creating lots of actions?? Maybe
this is a motivation to move to JSF!!
