[patch] [cla] Fix for cross window widget building in IE

[guest]

Problem: Opening a popup window in IE and trying to build widgets within in it via Dojo from the main (opener) window. Error Message: Interface not supported in IE 7 or obscure error code in IE6 Problem: IE cannot perform cross window DOM construction. In the current implementation, Dijit creates the node in the main document and tries to move it to the popup. Solution: Test that the temporary node used by _Templated is within the same document as the new widget.

The speed of Dijit rendering is important. I included a test is to measure the speed of widget creation.

This test also has a secondary purpose: The first is rendering a widget cross window in IE. While setting the context to the new window document was valid it wasn't sufficient - _Templated uses the same div to temporarilly hold the HTML during the creation of a widget. This fix checks if that temporary node is still within the current context and creates a new one if not. The second fix is if the widget was first created in the main page, and then created again in the popup window, adressing the cached status of the widget string. The only way (I could think of) to prform this test is to run the test a few times with the edits, and again without the edits. I added //IEFIX to _Templated so the two fixes could be switched out easily.

My personal tests showed a negligible difference rendering 1000 simple widgets.

_Templated test for fix and speed

I apologize for my test and first comment being too complicated. The test file should have probably been two files.

The fix checks that the temp node used in _Templated is still within the current dojo.doc. That pretty much sums it up.

Note also though that there are issues with cross window, as Dojo in both windows seems to forget where custom widgets. That's why I use getObject bfore changing teh context.

OK, that's a pretty trivial change; I can add that.

Hi Mike, I mailed you but didn't get an answer, so will write here. A couple problems with this patch.

• getting 404 error in the popup window in the test file.
• Firebug's NET tab tells me that in test_AccordionContainer.html (a random test), AccordionPane?.html is being loaded 9 times now, instead of once like with the current code in SVN.

Hi Bill, I guess we should have done this from the beginning. Apparently none of my emails reached you, and I tried different accounts.

I don't get a 404 in my test. It's not really loading much - I'm not sure what you are missing.

I checked in the large app I'm working on. We are pretty much loading the kitchen sink. And we do have the duplicate bug that you explain with one widget - button.html loads multiple times, and it didn't when I removed the patch. (The one widget we don't have is an accordian, and I also couldn't find that test).

There does seem to be some kind of edge case with certain widgets. The button.html is tiny; less than 1k. Perhaps that's a clue.

I'm sorry, but I'm slammed at work for the next few weeks and have to stay focused. I can either get back to this patch at that time, or you could remove it, leaving comments in there. It was more of a courtesy patch on my part - we opted to use a different technique other than widgets in a popup because there are just too many other IE issues - like dojo forgeting custom widget objects. But because my research took quite a few days, I felt it was important that some sort of record was made.
