Select does not submit form on change
Hi
I am trying to attach an event to a select. The guys that worked before me
used this model.
http://wiki.apache.org/tapestry/Tapestry5SelectObject
I have written this code so far:
<form t:type="form">
<t:selectObject t:id="courses" list="courses" value="currentCourse"
labelField="literal:courseId" onChange="form.submit();"/>
<t:submit/>
</form>
void onSubmit() {
System.out.println("Value changed!");
}
Whenever I change the value from the select nothing prints on the console.
If I press the submit button, I get output in the console.
I am stuck the whole night on this.
Thank you

What was your way out mite.How did you get it working
But anyways, do you think writing a java script for submitting a select
should be the ideal way that it should be working?
Thanks

Try using onSuccess() instead of onSubmit().
By the way, instead of relying on onchange="", use Prototype events:
<form t:type="form" t:id="form">
<t:selectObject t:id="courses" list="courses" value="currentCourse"
labelField="literal:courseId" id="select"/>
<t:submit/>
</form>
<script type="text/javascript">
Event.observe('select', 'change', function() { $('form').submit(); } );
</script>

I will be more specific then.
What you need to do is:
- Use Firefox and Firebug (or some other request monitoring tool) to see
what happens when you select something in your select. Is any event trigered
in the browser. Is something sent to the server?
- Check on the server side if the page class is at all contacted. Set a
breakpoint in your onActivate method or something similar.

Re: Select does not submit form on change

No, I just have the function:
void onSubmit() {
System.out.println("Value changed!");
}
<t:selectObject t:id="courses" list="courses" value="currentCourse"
labelField="literal:courseId" onChange="this.form.submit();"/>
which prints to console when a submit is made, but it does not print
anything when I change the value.
Are you using some debug tool to verify if a request is sent to the server?
Like firebug in firefox? Are you getting a javascript error when you select
something?

You're not giving us very much information to work with here...
Are you using some debug tool to verify if a request is sent to the server?
Like firebug in firefox? Are you getting a javascript error when you select
something?

The only way I got this to work was via Javascript called from the
select to do the submit.

Re: Select does not submit form on change
Posted by Inge Solvoll <in...@gmail.com>.
I solved this problem just a few weeks ago myself :) It is a very bad bug
that is very hard to track down, the only error is "submit is not a
function".
The solution is to assign an id to your submit button, like this: <t:submit
id="saveButton"/>. You should always do that anyway, it makes code clearer
and it is easier to test with tools like selenium.

Now I am replying to myself ;)
Of course it doesn't work - prototype is not automatically bundled with
such a simple page - will have to do that manually.

AFAIK, t:id can't have a space on it.

Yes, and it has a purpose. When a component is put inside a Grid or Loop,
it has one t:id, but each generated HTML tag a different id.
t:id is a Tapestry component id. id is the HTML id.

Huh :( I never thought about putting t: prefix on id.
- t:id="my submit" - works
- id="my submit" does not work
Does this mean that theoretically a single component can have two id-s?
One tapestry id, and another non-tapestry one?

I think this should be a JIRA issue in T5. If you don't specify an id for a
submit, T5 generates name="submit", which breaks form javascript. T5 should
generate a safe default name for submit component.

Hi,
Its because, when you do not assign t:id to a submit button, it assigns
name="submit"
which has a conflict with any other submit in your page(even through java
Script)
i got it working with t:id="My Submit" then even on Change works.
This is such an irritating error that we have put it our development
checklist to check that there is no submit button with name as submit.
Thanks

This is a Prototype function, documented here:
http://www.prototypejs.org/api/event/observe. If Prototype wasn't added
automatically by some Tapestry component, you can easily add it by
annotating your page class or component with
@IncludeJavaScriptLibrary("${tapestry.scriptaculous}/prototype.js").

This issue is not really a problem of Tapestry, this is a Javascript
browser implementation problem.
In my code sample this works in IE 8, and it does not work in Firefox
3.6 or Opera 10
Take the submit button out, and it will work with no problem.
So, What exactly happens in for example Firefox is that when you add a
Submit button, the Submit() function is overriden with the Submit button
and it becomes a property.
Now the form.submit is not the function for submitting any more, but in
fact now it is the submit button itself.
I think that I never ever had a need to use a button and a list for
submitting at the same time, so I never saw this as a problem.
But, the bad thing is that here Thiago's solution does not help - with
it I get an
Event.observe is not a function
And now it does not work even in IE.
