One customer has raised such question "Currently all our dialog templates we have similar code repeated over and over. For example we have added a wysiwyg field in all our template for which we have written same groovy code in all our dialog templates. Is it possible to externalize the code in a separate groovy template and refer it in all the dialog templates so that we can centrally change our dialog templates if needed."


We've got the answer from eXo.

*********************************************************************************
To include groovy snippets in the dialog template you can use :
_ctx.include(TemplatePath);

To get the path of the templae :
import org.exoplatform.services.cms.templates.TemplateService;
  
  public String getTemplatePath(boolean isDialog, String nodeTypeName, String templateName) throws Exception {
   TemplateService tempService = uicomponent.getApplicationComponent(TemplateService.class);
   String path = tempService.getTemplatePath(isDialog, nodeTypeName, templateName) ;
    return path;
  }
For example

Example 1 : to embed the template of vote & comment for view template
<div><% _ctx.include(uicomponent.getViewTemplate("mix:votable", "view1")); %></div>
<div><% _ctx.include(uicomponent.getViewTemplate("exo:comments", "view1")); %></div>

Example 2 : to embed the dialog template of exo:podcast for an other dialog template
<% 
   import org.exoplatform.services.cms.templates.TemplateService;
   TemplateService tempService = uicomponent.getApplicationComponent(TemplateService.class);
   String path = tempService.getTemplatePath(true, "exo:podcast", "dialog1") ;

 %>
 
  <%
  _ctx.include(path);
  %>

Can we add this info to the developer guide so that the other customers could benefit from it?
