Hi Francesco,

yes, that's right, I saw that file. It is the one I was referring to, as 
a matter of fact.

Line 188 is

<map:generate src="sax-pipeline/{map:1}.xml" />

I have similar lines in my pipeline.

The difference is that I now have:

<map:match pattern="create/image/creator/*">
   <map:generate type="new-image">
     <map:parameter name="creatorId" value="{map:1}" />

Thus, I am trying to pass a parameter to the Generator. When checking 
the parameter in the Generator, it is always null. In fact, there are 
many parameters available to the Generator (not set by me) and the 
'creatorId' is the only one that is null.

The request that I was using


should however give a value of 3276800 for creatorId.
