All the values put into the model are directly accessible. In your example FTL, you would use "&lt;#if validValues??&gt;" and so on.</SPAN></BODY></HTML> Fri, 22 Jan 2010 07:58:10 GMT https://connect.hyland.com/t5/alfresco-archive/java-backed-webscript-no-model-object-in-ftl-template/m-p/232428#M185558 lyamamot 2010-01-22T07:58:10Z Re: Java Backed Webscript: no model object in ftl template https://connect.hyland.com/t5/alfresco-archive/java-backed-webscript-no-model-object-in-ftl-template/m-p/232429#M185559 <HTML><HEAD></HEAD><BODY><SPAN>Now, I'm ashamed!
