I have a parameter name= navigation and its value is shown as {submitText}.

I hope I read your reply correctly.
You should NEVER EVER see "{submitText}" when you're stepping through
Java, or in the log window, or in an exception stack trace!!! The ONLY
place it should appear is in your JSP. In ALL OTHER PLACES, you should
see the text that you put in your MessageResources.properties. If
you're seeing "{submitText}" verbatim, then your JSP compiler is
ignoring EL, or it's not written correctly. For this line in your JSP,
hiddenField.value = "${submitText}";
Go ahead and request your page in your browser, then go to view source.
Scroll down to where this line should appear in the HTML, and make sure
it says something like,
hiddenField.value = "Next";
instead.
Now there might be a workaround... I gave you the EL method because I
find it much cleaner than embedding XML-like tags in JavaScript, but the
following may also work in your JSP:
hiddenField.value = '';
This might work... I don't LIKE it, because it's an XML (tag library,
whatever) tag inside JavaScript inside HTML in a JSP... but oh well.
Note the quotes -- the outermost are single quotes, the innermost are
double quotes. Double check them even if you copied/pasted them just to
get into the habit.
If you were using {submitText} in your post as a placeholder for the
actual text that should appear to the browser, my apologies, though I
hope you understand what I was getting at :).
If this WAS the case, since you're not using EL, feel free to remove the
lines I gave you in an earlier post,
As you don't need them.

Any idea?
Can you post the Javascript again? The most recent version I see
above never submits the form. It's not enough to name the method
'onClickSubmit' -- you actually have to call submit() somewhere, and I
don't see that happening.

Re: Question about Lookup dispatch action
Thanks for your help guyz. It doesn't seem to work.
The value of submitText is not passed to the hidden.value
The form gets submitted but gives an error
Request[/planName] does not contain handler parameter named navigation
I am pasting my code below.
function onClickSubmit() {
var hiddenField = document.getElementById( "hiddenNavigation" );
hiddenField.disabled = false;
hiddenField.value = "${submitText}";
alert(hiddenField.value);
document.planNameForm.submit();
}
Thanks again!

Well first you should probably get rid of 'value="Previous"', since you
should be (and are) setting the button text using .
I didn't consider you were using regular buttons as well. In this case,
the hidden field is going to be sent, and might muck up
LookupDispatchAction when the user clicks a regular button. So what you
might need to do is something like this:
I can't guarantee having the "disabled" there will work, but it should
prevent the web browser from sending an extra (blank) "navigation"
property and possibly causing the bean helpers to discard the REAL
"navigation" value (when a button is clicked). Then in your JSP:
function onClickSubmit() {
var hiddenField = document.getElementById( "hiddenNavigation" );
hiddenField.disabled = false;
hiddenField.value = "${submitText}";
document.navigationForm.submit();
}
Have fun,
Scott
OK One more thing, if you need to call this javascript method even from ur
submit button, to set the property value then you can do
Notice the return false there.
In case of a link simply do
I hope this was what you wanted.

I have another requirement now, I have multiple images that are going to be

So in my javascript, I will have to submit the form. How can I change/ set

It is giving me error:

Thanks for your help,
In your onclick handler for the images, change the (presumably) hidden
form input field value:
document.forms["form-name"].elements["navigation"].value = "new-value"
Then, submit the form.
This is in Firefox. Looks like it works for IE as well.
Not really a Struts question -- just straight Javascript...
Doesn't he need to match up the message resource values, like if he had,
protected Map getKeyMethodMap() {
Map map = new TreeMap();
map.put( "form.create", "create" );
return map;
}
Then it would take a little trickery in the JSP to get the right values
in the Javascript:
So the web browser passes the correct value, and the lookup map will work:
function onClickCreate() {
document.someForm.action.value = "${createLabel}";
document.someForm.submit();
}
That should do it I think...
