[Zope] Debugging and DTML

Hello, I'm developing a product for ZOPE. Because changes in the python and dtml files are not detected I need to restart the ZOPE server all the time. Is there a way get around this? How can I list a dictionary (e.g the REQUEST) with dtml. In python I would do the following: for i in REQUEST.keys(): print "%s=%s"%(i,REQUEST[i]) And with DTML? Here is the peace of dtml I came up with. But it doesn't work! I look in documenation but ... What is wrong? <dtml-in "REQUEST.keys()"> <b><dtml-var sequence-item>=<dtml-var "REQUEST[sequence-item]" ></b><br> </dtml-in> Thanks Alfons
