#72 FireEventNoWait hangs when ModalWindow opened

[Anonymous]

Thanks for your very good library!

I have one problem with FireEventNoWait method, below is the code snippet to reproduce it:

// Work with popup.html from WatiN regression tests
IE ie = new IE("...watin\tests\popup.html")
ie.Button(Find.ById("modalid")).FireEventNoWait("onclick")

Last statement hangs until modal mindow is closed. This makes impossible to access modal windows which are opened by other events like "onMouseUp" (my case).

I've also tried to run it in separate thread, it works for me, but when I close dialog programmatically (Button.Click), I get an Exception:

IronPython Stack Trace:

File Microsoft.mshtml, line unknown, in get_readyState
SystemError: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))

On the other hand Button.ClickNoWait() hangs when I try to use it.

Thanks for the report. I can reproduce the problem. The code seems to hang
when WatiN is firing the onclick event on using javascript
injection. The code that is injected is

var newEvt = document.createEventObject();newEvt.button = 1;document.getElementById('ms__id2').fireEvent('onclick', newEvt);.

calling the onclick where a dialog will show up should be done asynchronous to avoid the injected javascript is waiting for the result of the onclick. Maybe using a timer in javascript to call a function that calls FireEvent will do the trick.

I'll need to give this some thought.

Bug is fixed, FireEventNoWait didn't run the command asynchronous against the browser. Fix is available in the current development code on SourceForge and will be part of the 1.3 release.

Thanks for the report!
