button dialog works in one place, fails in another

[rlad]

I'm trying to use simpledialog2 in button mode, and it's working in one place in my program but fails in another.

Where it fails, the dialog either doesn't appear at all, or appears for a moment, then disappears. Even when it's not there, touching the screen triggers button events (which appear in the console log).

The place where it doesn't work is a listview managed by Jquery Scrollz for lazy loading:

Here are examples of the code that works and doesn't work:

Any help would be appreciated!

I solved it by increasing the zindex to 10000. But then another problem cropped up: clicking a button on the dialog also would produce a click event on the listview under the dialog.

I solved that one by putting in a delay of 400ms during which time I ignored subsequent click events. I'd hope that such kludges wouldn't be necessary though!
