Will Glass-Husain updated VELOCITY-374:
---------------------------------------
Bugzilla Id: (was: 34478)
Fix Version: 1.5
Description:
VelocityEngine throws a strange NPE if it's not initialized. It'd be better
if it threw an Exception with a meaningful error message.
>From [EMAIL PROTECTED] <[EMAIL PROTECTED]>
I had another problem that I think can help others in the future. In looking
through the archives I noticed other people having the same null pointer
exception I was having. I went through the code and noticed that if a person
did not "init()" a velocity engine, the resourceManager never gets
initialized. When they call the function below in RuntimeInstance.java, they
get the null pointer exception.
public Template getTemplate(String name, String encoding)
throws ResourceNotFoundException, ParseErrorException, Exception
{
return (Template)
resourceManager.getResource(name,
ResourceManager.RESOURCE_TEMPLATE, encoding);
}
ERROR [http8080-Processor2] TemplateToStringManagerBD.getContentAsString() -
VelocityEngine failed to merge the template.
