JMeter doesn't save parameter for Java Request

java, jmeter, parameters, performance-testing

Solution

As documentation states

The Add/Delete buttons don't serve any purpose at present.

In other words: you can only add a new parameter programmatically in the code of your sampler:

@Override
public Arguments getDefaultParameters() {
    Arguments params = new Arguments();
    ...
    params.addArgument("SCENARIOS_ID", "...");
    return params;
}        

Problem

I want to add to existed Java request new parameter. I could add it.However, after save it disappears. Here is look when new param is added: After pressing save for this test plan: I couldn't understand why does this happen. Version of JMeter - 2.11 Any suggestions?
