Changing user defined variables in JMeter

Question

I have a custom JMeter sampler, which derives from AbstractJavaSamplerClient. In this sampler, I want to change a user defined variable in the JMeter GUI after the sampler finishes. I can access user defined variables using

JMeterContextService.getContext().getVariables() 

but changing values in these variables using the put method does not reflect in the GUI. Is this even possible?

Answer 1

No it's not possible as when you do this, it is on running copy of components.
