This change was not fully thought through, but in next release I will add configuration parameter
"Selected value" which will have value: "none, top, default" (default will by 'none') and help description. "Which value is selected, after loaded parameters". I think this good resolving, do you agree with me?
Selecting values is realized in java script on browser. When you run job by timer plugin returned default value or blank when you not set default value, because Jenkins invoke method
public ParameterValue getDefaultParameterValue()
