Debugging templates that have #include or #parse
Hi all,
I have this problem on rare occasions, but I've never found a way
to resolve it...
Say I have a template named "template.vm" that has something like:
<html>
<head>
<title>Page Name</title>
</head>
<body>
#parse ( "macros.vm" )
#parse ( "navbar.inc" )
#set ( $foo = "some val")
.
.
.
I'll find some velocity error in the logs, like:
Velocity [error] Error in evaluation of == expression. Both arguments
must be of the same Class. Currently left = class java.lang.String,
right = class java.lang.Long. /template.vm [line 10, column 42]
The error is indicating line 10 in the /template.vm file, but the error
is actually in one of the #parsed files, so locating the error can be
difficult at times.
Is there a way to expand the template so that it shows all of the velocity
code un-parsed? As I recall long ago, C had a way to show the contents of
a .c file that would expand macros and show the contents of include files.
TIA,
Doug

Yeah, Doug, version 1.4 definitely had issues with this sort of
debugging output in the logs. Hope you can upgrade...

I'm embarrassed to say that I'm still running an older version, 1.4. I'll
be upgrading soon, so I'll do some more complete testing and see if I
can duplicate this problem before posting again.

The error in the logs should have the proper template name, line and
column. If not, that is a bug. What version of Velocity are you
using? We have had bugs like that in the past, but i thought they
were fixed.

No, Velocity has no support for that.
