Subject [jira] Updated: (BEANUTILS-35) Indexed properties with Array type cause IllegalArgumentException in setProperty/populate
Date Sun, 15 Jul 2007 02:27:04 GMT


Niall Pemberton updated BEANUTILS-35:

    Attachment: BEANUTILS-35-PropertyUtilsBean-getPropertyType.patch

I agree there are IMO flaws in how BeanUtilsBean's setProperty() method determines the type
to convert to for simple properties that have indexed or mapped descriptors. I started work
on a new getPropertyType() method for PropertyUtilsBean that I believe resolves these and
could be used to replace that logic in  BeanUtilsBean's setProperty() method.

Attaching a patch to demonstrate the idea - I haven't yet tested this method or tried plugging
it into BeanUtilsBean's setProperty() method. Also need to review if there are any adverse
implications on compatibility of implementing this.

P.S. If this approach is OK then also use for LocaleBeanUtils.
