PropertyUtils.getNestedProperty() doesn't allow getXxxx on Map-Instances any longer

           Summary: PropertyUtils.getNestedProperty() doesn't allow getXxxx
                    on Map-Instances any longer
           Product: Commons
           Version: unspecified
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Normal
          Priority: Other

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
