Subject [jira] Commented: (AXIS2-1883) Integer nillable property of input parameter bean cannot be null (NumberFormatException in SimpleTypeMapper)

David Garcia commented on AXIS2-1883:
-------------------------------------

Hi again,

Finally, we´ve decided to fix bug on the assumption that null values are allowed to pass
through SimpleTypeMapper.
To solve all our issues with null values we also had to fix AXIS2-1745; that´s why we´ve
attached a patch for BeanUtil.

Both patches have been generated against the latest sources in the "1_1" branch.

We have thoroughly tested this solution with our use cases and it works fine so far :-)
I hope it also works for others.

BTW, I´ll post another comment on AXIS2-1745 to link here.

Cheers,
   David

> The only way to make it work is to change "someInt"´s type to "int" and pass "0" as
default value, although most time this workaround is not desirable as it breaks the operation´s
semantics.
