Thanks Sebb: I've set the 'Label' input of a Java Request/JavaTestsampler in the first thread group to:${__setProperty(property,${variable})}This successfully sets the property to the variable value; I can now useit in the second thread group. Is this behaviour of User Defined Variables (in my earlier testplanbelow) worth a bugzilla entry?> 'HTTP Sampler 2' is just a dummy request that appears to 'fix' the> property set in thread 1. If I remove that sampler the propertyappears> as '${some_jmeter_variable}' (instead of the JMeter variable's value)> the second thread group.
