Re: [Webunitproj-users] random errors - please help!

[Doron <dg...@sh...>]

Hi Brian,

	Sounds like there maybe a spurious timing issue (hard to solve as it is
spurious). It would hard to debug it without actually being there. Is
there some javascript that changes the page while web unit is trying to
do something?

	It looks like the error is here:

com/zeborg/webunit/ie/ExplorerNativeWebClient.setOption
(ExplorerNativeWebClient.java:65

	You may want to look at that line of code and see what would cause a
null pointer exception there.
