Its an utility method by liferay to retrieve parameter from request, which will save you from nullpointer exception

It is same as writing the following lines

1long resourcePrimkey = 0;
2if(request.getParameter("resourcePrimkey")!=null){
3 resourcePrimkey =Long.parseLong( request.getParameter("resourcePrimkey"));
4}

Hi,

'resourcePrimkey' is just the name of a parameter. If it is not declared in the page that your are reading (probably a fragment) that it must be declared in parent pages.
If you need more helo, please tell us which file are you reading.

If you search within jsps files in the slogan context portlet you will find parameters named 'resourcePrimKey'.
These are the parameters that are read by the actions java files, using ParamUtil utility, to perform their tasks on specific slogan entity.

Please find the following link about workflow setup in custom portlets:
