Description

Hi there!

For a long time we use Struts 1.0 and <bean:write ...> on objects derivated
from Map.

Back then <bean:write name="obj1" property="obj2.obj3"> did a obj1.getObj2
().getObj3(), even when obj2 was an object derivated from Map.

Since Struts 1.1 the bean:write above does not any longer access "getObj3()".
Instead it does (in PropertyUtils.getNestedProperty() ) "if (bean instanceof
Map)

{ bean = ((Map) bean).get(name); }

" - in my example: obj1.getObj2().get
("obj3").

This causes a massive incompatibility with JSP pages generated under Struts
1.0. We have several projects with this problem if we would upgrade them to
Struts 1.1 (which would take some time cause it means redesign of all classes
that are derivated from Map and accessed via <bean:write> and other tags).

I hope there can be an alternative solution provided by Struts!

Thanks for the time,
Thomas Sahling
