If we invoke it twice in a row: {{hello greetUser="true" /}} {{hello /}} The second invocation will not print "Hello World!" as we'd expect. But it will print the same result as the first invocation. The reasons are: * Macro parameters are implemented as global parameters. So, they remains the same across multiple macro invocations. * If $context.macro.params.greetUser contains "null", it will not be assigned to $greetUser. This is different from C/C++ or Java. So in order to get around it, you can use: #set($greetUser="$!context.macro.params.greetUser") Tags: [+] <http://platform.xwiki.org/xwiki/bin/view/DevGuide/WikiMacroTutorial?showTagAddForm=true#xdocTags> Created by Asiri Rathnayake <http://www.xwiki.org/xwiki/bin/view/XWiki/asiri> on 2009/07/20 08:30 Last modified by Thomas Mortagne <http://www.xwiki.org/xwiki/bin/view/XWiki/ThomasMortagne> on 2010/05/12 19:42 How can I add the Last Modified by in the bottom by the Created by like on Xwiki.org? Should be an easy way but I can't seem to figure out how to add code below the page like that. Is it in the Admin tools? If so where in there?
