Show Parameter Name, not its value?

[mwarner_2]

Maybe this is real simple, but I don't know how.

 

I want to show in a text field the name of the parameter, not its value.  Something like:

Selected [parameter name]: [parameter value]

example:
Selected City:  Athens

 

So the text field would be something like "Selected " + $P{City}.name + ": "  + $P{City}

But I don't know how to do the parameter name part of this.

I want to do this so that if I change the Parameter Name, then it is automatically updated in the report (versus if I manually typed the parameter name into the text field).

How are you going to distinguish between several parameters? That is, if you have $P{City} and $P{Town}, and you decided to change $P{City} to $P{State}, how do you expect JasperReport to know that you've change ${{City} and not $P{Town} to ${State}?

If you just want to display name, you can just create 2 parameters - one for name and one for value.

I asked if it is currently possible to show/print/display the parameter name, and apparently it is not.

There might have been a secret convention like $N{City}, whereby its use would give the name of the parameter and not its value.
