children binding doesn't resolve a bean's property correctly under a namespace

Steps to Reproduce

1. run the attached zul
2. compare the content of 2 vlayout

Current Result

the EL in the first vlayout, each.country, is not evaluated to country. It's actually result to each.toString().
The 2nd vlayout content is expected.

Expected Result

the content of 2 vlayout should be identical

Workaround

• make zul as the default namespace
• replace with <forEach>
