[xwiki-users] xwiki Macro using groovy

Hi everyone, Thanks so much for your quick answer on my previous question. I am trying to write a bibliography/cite macro (I am happy to share once it dies something useful). I am writing the macro in a wiki page and I am using groovy as scripting language. I would like to have access to the URL of an attachment of the page the macro is used on. I am doing so by using doc.getAttachmentURL( <name> ); however, the URL uses the page the Macro is saved in, not the page the macro is used on. I think I managed this before using velocity. So my question: what would be the right way of accessing the Document of the page the macro is placed on? Thanks for your help, --Alaina
