[T5.1.0.5] 'Tapestry' is undefined JavaScript error on form submit

[Eric Ma]

I have a simple form:

<form t:id="myForm" t:type="Form">

T5.1.0.5 turns it into:

<form enctype="application/x-www-form-urlencoded" onsubmit="javascript:Tapestry.waitForPage(event);" action="../myClass" method="post" id="myForm" name="myForm">

What is this extra bit onsubmit="javascript:Tapestry.waitForPage(event);" for?  IE 7 gives a runtime JS error: 'Tapestry' is undefined.  However, the form gets submiited properly.  So this is not a show-stopper.  It is simply an annoyance.

Any suggestion how to suppress this event handler?  Thanks,

Eric

That's odd because I've tested this under IE 7 and it works.  Anyone
else seeing this?

Thanks for the reply Howard.  One thing I notice is on the page where this JS error occurs, the <form> element is in a custom component, not in the page directly.  In all other pages with <form> elements, IE 7 is perfectly fine with the onsubmit event handler.

So it appears somehow the main Tapestry.js file is not included properly with components.

Well, you could verify that with a "view source"; it seems unlikely to
me, but that would be a start towards investigating this.

This problem can also be cause by some previous Javascript error. Using  
Firebug and/or Web Developer can help to figure out what's happening.

Well, I had never had the need to explicitly include tapestry.js, until today that is. T5 apparently does its magic behind the scenes.  Plus, when doing View Source for the pages in which the onsubmit handler works, I cannot find tapestry.js.

After explicitly adding @IncludeJavaScriptLibrary({"classpath:org/apache/tapestry5/tapestry.js"}) to the custom component, my problem is now resolved.  Howard, does that give you a clue how to solve the problem at the root level?
