Is ParameterTypeCheckBoxGroup no more supported?

Haoyang

I was building an operator with ParameterTypeCheckBoxGroup, and I find when I want to get the parameters, it returned null
ParameterTypeCheckBoxGroup leads=new ParameterTypeCheckBoxGroup(PARAMETER_LEADS, "choose the leads to focus on"); for (String lead : leadName.getLead()){
leads.add(null,lead);
}

step.focused_leads= stringToSelection(getParameterAsString(PARAMETER_LEADS));

Hi,

i hope you figured out in the meantime how to use it, there is also an usage example on github:

Hi @Haoyang,

I saw you posting multiple questions around creating your own extensions. Unfortunately, I don't know the answers myself, but wanted to make sure you are aware of the documentation that can be found here: For Developers - RapidMiner Documentation

Have a nice weekend
