Dev questions

Hi Gang ! I've got some questions concerning the development of XWiki extensions : I've written a simple radeox macro that output a table; basically, it outputs "{table}" with contents in the macro writer. It works really fine until I decided to use the macro content (params.getContent()) ! If I only use my macro like this ({mymacro:<params>}), outputed tables seems to be interpreted correctly. But if I have the content ({mymacro}<content>{mymacro}), inner {table} seems to be no more interpreted. Why ? Other question : Is this possible to configure a radeox macro as easily as an xwiki plugin ? With XWiki plugins, you have a context, and then you can access the Wiki and its configuration. But how can I do the equivalent with radeox macro ? Thanks Guillaume
