Converter trying to set String on int field
I have a bunch of check boxes called userId. In my action I have int
userId[] and setUserId(int[] ids)
When I select a checkbox the conversion works normally. When I dont
check any boxes on the form and submit, I get the following:

For some reason when no ids are selected it is trying to set the value
as a String.
1) Is this normal behavior?
2) Is there a way to work around it?
Thank you,
Rich

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.

Re: Converter trying to set String on int field

It is also happening in a Date field I have. If no dates are entered
in the text box then I get the same error. If I provide a date then
the conversion works.
I am currently moving through the XWork and OGNL source to see what is
causing this.

I bet it has something to do with a null not being assignable to an int.

After some further investigation I found that any array type that has
no values from the form on submit will call setXXX(String).
I checked the source of
com.opensymphony.xwork2.util.XWorkBasicConverter and this is the first
thing it does:
if (value == null || toType.isAssignableFrom(value.getClass())) {
// no need to convert at all, right?
return value;
}
So I'm still unclear as to why setXXX(String) is called. I even used
a custom converter, and I am getting the same results. When I return
null from my converter setXXX(String) is called.
If anyone has any suggestions on how to handle this it would be
