Item11917: Update JQueryPlugin simplemodal plugin to version 1.4.2

I know it has been deprecated, but it is still in use.

Upload to Extensions has failed, I've given up after 5 times server error.

Newer releases of simplemodal have been buggy with regards to resizing the modal dialog. That's why I did not update it for a log time. Besides, yes, better use ui::dialog. It is superior in so many ways.

This code is now out at JQueryPlugin. Could we please please please talk things like these thru before rushing out a new release!

After some initial testing, the new simplemodal behaves strange now while determining the height of the dialog window. Dialogs in NatEditPlugin, TopicInteractionPlugin and MetaCommentPlugin have a wrong height now all: showing whitespace underneath the dialog, or shrinking the dialog for no good reason. Checking the changes ...

Reopening and switched from "Enhancement" to "Urgent"

This patch cures it:

                        s.d.wrap.css({overflow: (dh > ch || dw > cw) ? 'auto' : 'visible'});
                        s.o.autoPosition && s.setPosition();
                },

The plugin basically fails to compute the container dimensions correctly. In fact, I am not sure why it should alter the height at all. So I disabled this part all together.

I checked in this patch to trunk. Release branch pending.

Arthur could you please check?

With the patch I have problems with large modal windows.

If I use maxHeight: '90%', it works fine with the simplemodal code, not with this patch. The result is that the modal window is higher than the browser window, and the modal window extends beneath the browser top, obscuring the close button.

Possible reasons why height calculation may not work:

• To use a fixed height, you must set both minHeight and maxHeight.
• To set a size relative to the browser window, use percentages like maxWidth: '90%', maxHeight: '90%'.

There are also a couple of issues with height mentioned on the github issues page https://github.com/ericmmartin/simplemodal/pull/4.

I can't find an issue with the smaller dialogs on TopicInteractionPlugin (the large dialog won't appear, it leads to an attach page). So before looking into it further I would need to know what problems you see.

I already told you what problem there is: it does not compute the height of the simple modal container correctly.

To display lengthy modal dialogs it is best to create an overflow area yourself within a fixed size modal and let it display a scrollbar itself based on a max-height setting.

The other "solution" is to simply forget about simplemodal and switch to ui::dialog as I told you already.

"Arthur could you please check?" => your patch doesn't work for my cases. I try to understand what you mean by "fails to compute the container dimensions correctly". Unless you provide me with more specific information why it fails in your cases (and why your patch does work in those cases), my checking is done here.

My motivation to improve on this plugin is that I am sure it is being used. I have encountered it in the TagMe ajax interface. So a solution could be to fix those instances to use ui:dialog. However that will take more time.

Errors with your updates:

Fixes after my patch:

These are only two examples. There are more with even stranger heights being computed. So it is better to disable that feature by now. I already talked to the upstream maintainer over a year ago about this problem...
