Jarek Gawor resolved GERONIMO-4407.
-----------------------------------

       Resolution: Fixed
    Fix Version/s: 2.2
                   2.1.4
         Assignee: Jarek Gawor

Committed fixes for this problem to trunk (revision 721726) and branches/2.1 (revision 721729). The better solution for this problem would be to rewrite the code to use one map for attributes (instead of 3) and one map for references (instead of 2).

> While an attribute's initial value is no-zero length  value, then we set  its value with zero-length value in the portlet, then we could find the in the config.xml file, there are  duplicate attribute entries.
> Like 
>             .......
>             <attribute name="LoginTimeout">0</attribute>
>             <attribute name="ShutdownDatabase">shutdown2</attribute>
>             <attribute name="ShutdownDatabase"/>
>             ......
> It seems that it is caused we use two Map (attributes, clearAttributes ) to keep the attribute values, while we setting the attribute, no code checks that the attribute should only exist in one map.
