Hi,

I am trying to retrieve a task form but I keep receiving a NullPointerException:

…
Caused by: java.lang.NullPointerException
   at org.activiti.engine.impl.form.JuelFormEngine.getFormTemplateString(JuelFormEngine.java:62)
   at org.activiti.engine.impl.form.JuelFormEngine.renderTaskForm(JuelFormEngine.java:48)
   at org.activiti.engine.impl.cmd.GetRenderedTaskFormCmd.execute(GetRenderedTaskFormCmd.java:62)
   at org.activiti.engine.impl.interceptor.CommandExecutorImpl.execute(CommandExecutorImpl.java:22)
   at org.activiti.engine.impl.interceptor.CommandContextInterceptor.execute(CommandContextInterceptor.java:37)
   at org.activiti.engine.impl.interceptor.LogInterceptor.execute(LogInterceptor.java:33)
   at org.activiti.engine.impl.FormServiceImpl.getRenderedTaskForm(FormServiceImpl.java:44)
‍‍‍‍‍‍‍‍‍‍‍

The form works fine in Activiti Explorer and through the REST API, but it doesn't work if a use FormService.getRenderedTaskForm(taskId).

This is where I have the form in the process definition:

<userTask id="review" name="Review Document" activiti:formKey="dr-approve.form">
‍‍‍

I have tested the same code with the Vacation Request example and it workfs fine. I based my process in the Vacation Request example so I don't know why my form is failing. But again, the form works fine in Activiti Explorer and through REST.

Any ideas?

Thanks,
Luis Delgado

Problem is resolved…it seems that Tomcat was running a older version of my code cached in memory…
