After some debugging the culprit was the checkbox interceptor.
It uses false as a default value when nothing is selected. I tried
setting the uncheckedValue to -1 and it didnt work.
<interceptor-ref name="completeDefault">
<param name="checkbox.uncheckedValue">-1</param>
</interceptor-ref>
I upgraded to the latest version of Struts 2 and then it worked.
