custom validator js causes duplicated postbacks

[xue]

This happens only on IE, not FF.

When a page has a custom validator and a TButton, clicking on the button will cause postback twice (i.e., running index.php twice on the server side). TLinkButton looks fine. I haven't checked other postback controls.

Please check the associated functionality test (tests/FunctionalTests/tickets/index.php?page=Ticket191)

Unable to verify in Firefox 1.5, IE 7 beta1, Safari 2.0.3, opera 8, Camino 1.0.1.

I can verify that there is a problem with duplicated postbacks with a TButton. I'm trying to build a small testcase. The problem is however that it seems to occur randomly, it looks like it is related to the amount of components on the page, a lot of components means it occurs more often than with a small page.

I suspect there is some problem with a javascript (onclick?) event handler which submits the form twice sometimes, maybe related to a DefaultButton?.

If i can create a consistent testcase i'll create a new ticket.

Wei, could you test on IE 6.0? I think IE 7.0 fixed many problems.

See also #202.

...this is getting tricky. I couldn't verify the issue on another machine's IE. So let's wait for more issue reports.

Still unable to verify in IE 6

This is caused by google toolbar (beta version). Calling Event.stop(event) in postback fixes the problem (but it loses the feature of not stopping event.)
