DOTs, wild cards, and action mapping

I started using the wild-card support in action mappings (from a CVS 
build).  It works, but I noticed something strange (until I realized 
what it was doing).  So, I have a action mapping like:

         <action
             path="/areas/*"
             type="apackage.AreaAction">
             <forward name="success" path=".area"/>
         </action>

Then in some jsp I have:

	<html:link title="${area.name}" action="/areas/${area.address}">

Where area.address expands to '10.0.0.1'.  Struts will look for the last 
dot in an action and chop it off.  So I keep getting a string like:

          <a href="/managearea/do/areas/10.0.0" title="area1">area1</a>

So I am not using extensions in my struts configuration and I would 
intuitively think that I would get '10.0.0.1' back.  Is this an 
ambiguity that appeared with the new wildcard support that cannot be 
resolved (meaning I should never use '.' in any names) or is there some 
way to resolve this?  Perhaps I must always use extensions to combat 
this (i.e. action="/areas/${area.address}.bogus_extension" - which is 
fine by me as a workaround)?

   I should have noted that I am using tomcat 5.0 also.  I am not using 
Velocity, but merely JSP EL.  So no mixing.   In debugging, the EL is 
returning the right thing.  Struts is stripping the last .something 
assuming it is an extension.

   I guess barring any other comment I will just add a bogus extension to
make sure I have no more conflicts.

Thomas,

(Probably a) Dumb question ....

>From the "${area.name}" it looks like you're using Velocity Templates.  I
thought Velocity couldn't mix with JSP's like that (My impression from ch 17
of 'Struts in Action'.  How are you mixing the two?  (Or is there a Velocity
update which allows it?)
