I give up!
Hello all,
OK, I'm certain this has been asked several times and that how to do is buried
in the ref manual somewhere but I can't find this in the archive and its driving
me mad trying to figure it out:
I'm trying to call an object method from within an if statement in a template
like so, e.g.:
if ($user.hasDocPermission("Maintainer", "$document.id", $document.vnum))
but it fails to even hit the method (to my surprise, Velocity doesn't complain
about type mismatching, invalid referencing or anything, just fails silently)
If I hard-wire it like so:
if ($user.hasDocPermission("Maintainer", "abc12de", 1))
it works a treat...
My tiny mind is failing to understand something to do with escaping the quotes
here I think but I'd be grateful if anyone could point out what..
Could I perhaps use a directive to build the argument list first? I would then
need to know how to escape a double quote in a set directive, yes? My various
(horrific looking) attempts at this are throwing all sorts of parse
exceptions...
Thanks a lot for any help...

Hi Colm,
is the property $document.vnum returning an int or Integer?
Since using the digit 1 works, $user.hasDocPermission seems to be
requiring an int or Integer as last parameter (the first two params
seem strings). Note that velocity will not do typecasting (other than
Integer to int), so either $document.vnum must return int (or Integer)
or you will need a context tool that does the conversion.
The poor mans trick (no need to write a context tool) for converting
a String to an int:
#set( $n = 0 )
if( $user.hasDocPermission("Maintainer", "$document.id", $n.parseInt($document.vnum) )
:) Christoph

the Bean Method resolution works only if your methods really match
String get<name>(void)
So if getVnum() or getId() don't match that signature, you _must_ write
if ($user.hasDocPermission("Maintainer", $document.getId(), $document.getVnum()))
I've stumbled over this so many times, I basically gave up writing
short cuts just to avoid the errors.

Henning

The downside to that would be that the string '$document.id' would be passed
into the method...

Hi,
I read somewhere (must be "User's Guide", or "VTL Reference", at
http://jakarta.apache.org ), that single quotes are processed while double
quote are treated "as is" .
I am not sure whether it is for the #if statement, or something else, but I
think this might work ...
This would give something like :
if ($user.hasDocPermission("Maintainer", '$document.id','$document.vnum'))
I hope it helps, and NEVER give up !
