[SOLVED] SetName of Operator/Process

Hi,

I'll need to set a name of process. Process is a root node operator with atribute name.

For example:

<operator activated="true" class="process" compatibility="5.1.014" expanded="true" name="NameOfProcess">

Now I want to rename this Process, but I dont know how. If I take a root node:

process.getRootOperator()

He has not method setName, only getName. Is any way, how to set a name of process/operator through rapidminer api (5.1)??

Thanks for ideas
