This is a bug.  Please create a JIRA issue \
(http://issues.apache.org/struts/secure/Dashboard.jspa).


The attributes are pushed to the component using a handy utility, \
"org.apache.shale.util.ConverterHelper", that  uses the JSF converters to handle \
changing the string type to the target property value.  There is not a JSF converter \
registered for the TimeZone class.  

There is another way to handle this but I think the best option is to add a TimeZone \
converter.  You can register your own common chains command to handle creating the \
target JSF components.  

http://svn.apache.org/viewvc/struts/shale/trunk/shale-clay/src/main/resources/org/apache/shale/clay/component/chain/shale-clay-config.xml?view=log


There is a "PluggableLookupCommand" that looks for custom commands registered in the \
"clayCustomization" catalog.   You can register your custom catalog using the context \
listener in the web.xml.  

<command className   = "org.apache.shale.clay.utils.PluggableLookupCommand"
             catalogName = "clayCustomization"
             name        = "preprocessAddConverter"
             optional    = "true"/>

I won't go into the details here because I don't think you should have to do anything \
special for one of the runtime converters but thought it would be worth mentioning.
