Nathan Bubna commented on VELOCITY-728:
---------------------------------------
Just to make sure you know, you can't use #parse without an argument identifying which file you wish to parse.
What were you hoping/expecting to happen? A better error message? That's a fine idea, but that hardly qualifies as a "Major" bug.

[jira] Issue Comment Edited: (VELOCITY-728) NullPointerException

When I use Velocity on an RTF document, I would like Velocity to also tell me that the exception (e.g. one above) occurs on which line of my RTF document. Is that possible with the current engine?

[jira] Updated: (VELOCITY-728) NullPointerException occurs when
#parse() without parameter
Posted by "Jarkko Viinamäki (JIRA)" <de...@velocity.apache.org>.
[ https://issues.apache.org/jira/browse/VELOCITY-728?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jarkko Viinamäki updated VELOCITY-728:
--------------------------------------
Attachment: velocity-728.patch
This should fix it.
If #parse doesn't get an argument, a VelocityException is thrown with information where the problem occurs.
The previous code didn't obviously work and instead of throwing exceptions it just wrote things to Velocity log. This same problem is related to other directives as well (no checking whether we actually got the argument or not and no exception in case of error).
