Liferay,Dynamic Data List, template

Question

How can i create a template with velocity or Freemarker for DDL in liferay ? I have a DLL with some data, i would display it not as a table but as a menu beacouse data is defined as [link,text]. i tried this code: <#assign records = ddlDisplayTemplateHelper.getRecords(reserved_record_set_id)> <#if records?has_content> <#list records as cur_record> ll </#list> </#if> in ddl there are 4 records, so this code would return ll ll ll ll , but it returns : Expression ddlDisplayTemplateHelper is undefined on line 1, column 20 in 20155#20195#21230.

why? can anyone help me?

I guess it was clear, but to be on the safe side: The error message says that there's no variable called ddlDisplayTemplateHelper (or its value is null), so for some reason Liferay doesn't expose that tool to the template. — ddekany

What is that ddlDisplayTemplateHelper, I am unable to find any class with that name in Liferay 6.2. By the way what version of Liferay are you using? — Parkash Kumar

Using velocity, you can try something like this :

#set($records = $ddlDisplayTemplateHelper.getRecords(reserved_record_set_id))
#foreach($record in $records)
$record
#end

If you tried it using velocity, you have to add ddlDisplayTemplateHelper to the velocity context.

context.put("ddlDisplayTemplateHelper ", "<DdlDisplayTemplateHelper object>"); have a look at this tutorial for velocity : javaworld.com/article/2075966/core-java/…
