Simple JMX file that shows error
I am trying to get the name of a threadgroup as a value to use as part of a
filename. Google suggests that to do this I should use
${__BeanShell(ctx.getThreadGroup().getName())}
but when I use it in the filename textbox of a SimpleDataWriter node
I get the following error

others on the user mailinglist say that it works in other node types (samplers
/pre and post processors), just not listener nodes. Is this a limitation or a
bug?
I traced it as far as JMeterContext.java, where the threadGroup() method
returns NULL for some reason.
I am using:
