Re: [Xsltforms-support] IE9 subforms access error

[Jeremy F. <jf...@te...>]

The problem in IE9 was caused by having compatibility mode turned on.  Unfortunately, this does not correct the problem in IE8.  I'm not sure how to go about fixing the problem in the xsltforms.js as the issue appears to be with the appendChild method on a script element being generated in the XsltForms_load.prototype.run method for the show=embed.

				var scriptelt = XsltForms_browser.isXhtml ? document.createElementNS("http://www.w3.org/1999/xhtml", "script") : document.createElement("script");
				scriptelt.setAttribute("id", "xsltforms-subform-" + XsltForms_globals.nbsubforms + "-script");
				scriptelt.setAttribute("type", "text/javascript");
				var scripttxt = document.createTextNode(subjs);
				scriptelt.appendChild(scripttxt);

I've updated locally xsltforms.js to now be what's shown below and IE8 is working, looking forward to using subforms now:
				var scriptelt = XsltForms_browser.isXhtml ? document.createElementNS("http://www.w3.org/1999/xhtml", "script") : document.createElement("script");
				scriptelt.setAttribute("id", "xsltforms-subform-" + XsltForms_globals.nbsubforms + "-script");
				scriptelt.setAttribute("type", "text/javascript");
				if (window.addEventListener) {
					/* Firefox, Chrome, IE9 */
					scriptelt.appendChild(document.createTextNode(subjs))
				} else {
					/* IE8 */
					scriptelt.text = subjs;
				}

If anybody sees an issue with this approach, please let me know as I'm really just trying to get to the point of testing performance to determine if we have to move in a new direction or whether subforms is our answer.

Thanks,
Jeremy

Subject: Re: [Xsltforms-support] IE9 subforms access error

Hello Jeremy,
I am trying to upgrade our beta3 forms to 1.0 RC and implement subforms on one of our existing forms.  In firefox, this is working without a problem.  The sample writers.xml works fine in both firefox and IE9.  The difference between our application and the writers sample is that we are bundling our forms through a tomcat server via a servlet that does some preprocessing of the xml.  In the end, the xml that is passed to xsltforms is essentially the same. The big difference is in our xf:load which is:
 
<xf:load show="embed" targetid="generalSubForm" resource="FormLaunch?form=GeneralForm"/>
 
In debugging our webapp, the resource reference to the FormLaunch servlet works as expected.  In IE9, the server never receives the request.
 
In IE9, the profiler reports the following trace:
19262 -> Load FormLaunch?form=GeneralForm
48 -> Unexpected call to method or property access.
4 -> Dispatching event xforms-link-exception on <DIV class=" xforms-group" id="generalSubForm"/>
309 -> insert bftr_expce in bftrs_expcs at 0 - Data
0 -> Dispatching event xforms-insert on <SPAN class="xforms-instance" id="main"/>
1 -> insert loc_origin in locations at 0 - Data
0 -> Dispatching event xforms-insert on <SPAN class="xforms-instance" id="main"/>
 
  I went ahead and pulled in the writers.xml and replaced all of our form and subform with the writers.xml and the books.xml and experienced the same method or property access error using with the servlet resource reference.
 
I'm unclear as to where the unexpected call to method or property access is happening in the xsltforms.js, will continue to look, but wonder if somebody can point me in the right direction.
The IE9 debugger can help you to precisely locate this unexpected call (you should first set a breakpoint at line #4173).

Thank you for your feedbacks!
