topic Problem passing JavaScript function in Alfresco Archive https://connect.hyland.com/t5/alfresco-archive/problem-passing-javascript-function/m-p/236381#M189511 <HTML><HEAD></HEAD><BODY><SPAN>Hello,</SPAN><BR /><BR /><SPAN>I've got a problem here. I can't pass the method site.listMembers as a JavaScript function so FreeMarker will use it.</SPAN><BR /><SPAN>I have to add a property that comes with an aspect to the site object. Because the site objects returned by siteService.listUserSites() is a Java object I can't augment it with the new property, so I decided to copy all properties and functions that are needed by the FreeMarker file. Unfortunately this will not work for the site.listMembers method.</SPAN><BR /><BR /><SPAN>Excerpt from the JavaScript code:</SPAN><BR /><PRE class="language-none line-numbers"><CODE><BR />&nbsp;&nbsp;&nbsp;
