key problem with LookupDispatchAction

["Curley, John" <Jo...@NielsenMedia.com>]

Hi, All:

I have a form that has text boxes and submit buttons.  I am using a
LookupDispatchAction that uses a parameter called "userAction" to map the
appropriate button in the Action class.

<html:form ...>
...
<html:submit styleClass="smButton" property="userAction">
  <bean:message key='button.search'/>
</html:submit>

However, if a user has the focus on a text box and hits the <Enter> key.
The following runtime error occurs:

"javax.servlet.ServletException: Request[/emailAssociateAction] does not
contain handler parameter named userAction"

This is because the submit button was not actually mouse clicked on and
instead the <Enter> key was selected.

Can anyone let me know what the preferred way of correcting this is?

Thanks,
John

Hi,

One simple option is to disable the use of the Enter key to submit the form.
This can be done in JavaScript by a function like the following (disclaimer:
I am not a JavaScript guru by any stretch of the imagination :-)

  function noEnterKey() {
      // Not necessary for Netscape 4
      if (document.layers)
        return true;
      else
        return !(window.event && window.event.keyCode == 13);
    }

Then, for each of your text input fields, you'd have something like:

<html:text property="yourproperty" onkeypress="return noEnterKey()"/>

Cheers,
-Steve
