           Summary: AbstractVisualizer should implement TestElement
                    interface
           Product: JMeter
           Version: 2.3
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Main
        AssignedTo: [email protected]
        ReportedBy: [EMAIL PROTECTED]


I followed the jmeter_tutorial.pdf to create new component using the TestBean
framework.

Page 13 in the tutorial states:

"By extending different abstract classes, you can control the type of element
your component will be (ie AbstractSampler, AbstractVisualizer,
GenericController, etc [...]"

Both, AbstractSampler and GenericController implement TestElement, but
AbstractVisualizer does not, which leads to a ClassCastException when you follow
these instructions:

Solution: Make AbstractVisualizer implement TestElement.

Thanks,
Rico.
