[Users] Legend printing

[gbrun]

Hi everybody!

I've got a little problem to print layers legend. My code is similar to  
the one used for this example:  
http://api.geoext.org/1.0/examples/print-page.html

Firebug points this error out to me: 'encFn is undefined' for the line 279  
in the 'GeoExt.js' file.

I'm working with the GeoServer mapFish plugin. I don't know if the problem  
comes from this or from my GeoExt code, or even from my yaml file.

Does anyone know this issue?
