Httpunit 1.7 has the ability to react on onclick events 
properly where javascript is involved. This has led to a 
new handling of submits which is done in phases. The 
orchestration of the phases is important for avoiding 
double submits. 

Please try out the latest Subversion trunk. I think we 
have fixed this already. If your case is different we 
will probably be able to also fix it quickly base on a 
JUnit Test.

For a Junit test we'd need a version of your code that 
contains the culprit javascript and is runnable on the 
pseudo-server used by the junit tests.

In the bugreport and patch section of the website you 
might also find some hints and pointers to subversion.
