---------------------------

    Resolution: Fixed

The problem is that you probably didn't have the Velocity jars.  On startup, the managers are loaded, assuming all their dependencies are available.  Feel free to reopen if you find a reproduceable case where it is broken.

> Using Struts2 version 2.0.11, and velocity 1.5...
> If you create an action with a VelocityResult, there is an error when instantiating the VelocityResult due to the bean configuration in the struts-default.xml. This is what the error looks like:
> No mapping found for dependency [type=org.apache.struts2.views.velocity.VelocityManager, name='default'] in public void org.apache.struts2.dispatcher.VelocityResult.setVelocityManager(org.apache.struts2.views.velocity.VelocityManager)
> Adding a bean in your custom struts.xml like this:
> <bean class="org.apache.struts2.views.velocity.VelocityManager" name="default" optional="true" />
> seems to address the issue.
> Looking at the struts-default.xml there appears to be a mapping for this already there, but the name attribute on the bean is marked as "struts". I don't know if this is the source of the issue or not, but there does seem to be a mismatch and creating the same bean with a different name does resolve the issue.
> Later investigation with the application revealed that this is *not* necessarily a repeatable bug. I removed the bean entry from my custom struts.xml and the problem didn't resurface. I had to pull the original exception message from an older log. This would indicate to me that there me be some sort of load/configuration time timing issue that makes this somewhat indeterminate. Also note, there are a number of instances of this issue out on various forums on the web with no answers which makes me think it is hard to reproduce.
