                 Key: GERONIMO-4407
                 URL: https://issues.apache.org/jira/browse/GERONIMO-4407
             Project: Geronimo
          Issue Type: Bug
      Security Level: public (Regular issues)
          Components: kernel
    Affects Versions: 2.1.3, 2.2
         Environment: Windows XP
JDK 1.5.0
            Reporter: Ivan


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.
