Re: [Dynapi-Dev] IOElement Upload example

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

I've narrowed down the problem area.  In the IOElement Upload example,
Mozilla is "quietly" (i.e. can only be seen if you open the JavaScript
console from Tools->Web Development) throwing exceptions when the mouse
moves over and out of two of the form elements: the "name" text field, and
the "myfile" file field.  I started by looking at upload and text fields in
other non-DynAPI pages without any JavaScript, and they're not throwing
these exceptions in Mozilla.  Then I commented out all JavaScript code in
the IOElement Upload example page, and turned on one thing at a time until
the exceptions started occuring.  This happened when I turned on
dynapi.library.include('dynapi.api'); .  The JavaScript error messages are
as follows:

"name" text input field mouse over and mouse out (same error):

Error: [Exception... "'Permission denied to get property
HTMLDivElement.parentNode' when calling method:
[nsIDOMEventListener::handleEvent]"  nsresult: "0x8057001e
(NS_ERROR_XPC_JS_THREW_STRING)"  location: "<unknown>"  data: no]

"myfile" file input field mouse over and mouse out (same error):

Error: [Exception... "'Permission denied to get property
HTMLInputElement.parentNode' when calling method:
[nsIDOMEventListener::handleEvent]"  nsresult: "0x8057001e
(NS_ERROR_XPC_JS_THREW_STRING)"  location: "<unknown>"  data: no]

Has anyone seen this behaviour before?  Can anyone reproduce this error
message, or maybe give some insight where the problem may lie?
