Need a clarifcation about some issues
Hi,
I have been playing with Velocity in the past few days. By doing so I
encountered couple of problems. I'm not sure weather these are the
documented behavior so I thought I should ask the list.
1.I couldn't set a property after I initialize the Velocity Engine
(After calling the init() method). Here the particular property I was
trying to set was MAX_NUMBER_LOOPS property.
2.I couldn't call inner class methods. I put an inner class object in
to Velocity context and then tried to call its methods from the
template. But it didn't work. Velocity just outputs the calling method
name.
Thanks,
Supun.

Can you verify that the inner class (and the property accessor) is
public? I think introspection is blocked when a private/protected inner
class is involved, so it's possible that Velocity actually can't read
the values from your object.

No. Classes and methods that are private or protected should not be
accessible within a template. No need to open an issue for this.

Hi,
My inner class was a private one. When I made it public everything
worked well. Is it a issue that private inner classes are not working?
(Henning suggested to open a Jira).
Thanks,
Supun.

No, even VelocityTools uses inner classes extensively. If the class
is public and the method is public, you should be good to go. It
doesn't make any difference whether the class is inner or outer.

Yes, this is AFAIK a known restriction. Can you open a JIRA issue
for this so that it does not get lost?

Correct. Properties must be set prior to initialization/use of the
runtime. At this point, there is no support for changing properties
in a runtime instance that's already in use.

Christopher is right here. Inner classes work just fine (i use them a
lot), but they must be declared public just like any other classes you
are trying access in a template.
