Subject Cocoon Flow debugger errors
Date Tue, 25 Nov 2014 15:18:04 GMT
I am working on a webapp using Cocoon 2.1.11 with Tomcat 7.0.  I recently began using the Cocoon
Flow Debugger to help debugging our flowscript. To get it working correctly, I needed to run
the Tomcat7.exe program, instead of the Tomcat service we had previously been using, with
the debugger  option enabled in the cocoon.conf file.

I am able to access most pages of our web app with no issue.  However, a small number of important
pages that previously worked without error when using the Tomcat service with the debugger
disabled, will no longer load.

I found that the cause of the issue was an exception being thrown in the Form.js code when
attempting to build the binding.  
I found that in each case the error was thrown from the binding xml file when trying to use
the <fb:javascript> element. These widgets act completely normally when used in our
original environment and I am at a loss as to what could be causing it to throw an exception
only when the debugger is running.

The syntax of one example binding element is:

<fb:javascript id="otherassignees" path="." direction="save">
         var formValue = widget.getValue();
         var collection = new java.util.ArrayList();
         for(var i=0; i&lt;formValue.length; i++) {
           collection.add(new java.lang.Integer(formValue[i]));
         var bean = jxpathPointer.getNode();

The message shown when the exception is thrown says:

org.apache.cocoon.forms.binding.Binding Exception: Cannot build binding
at <fb:javascript>
(resource://org/apache/cocoon/forms/flow/javascript/Form.js, line 282)

If there is any addition useful information I have omitted please let me know and I will provide
it promptly.
