Define a Controller Portlet and bind the Parameter

1. Make a new Controller – see Create CONTROLLER Portlets (allows for recalculation of nodes in [TIS]Editor)
2. Open the recalculate operator and add a new line for a Parameter(repeat if necessary for each Parameter) 
   
3. Select the Parameters you want to be visible in the Portlet
   
4. Select the nodes to be updated
    

Create the Portlet with the corresponding interface to change the values of the Parameter

The steps are the same as described in: Create CONTROLLER Portlets (allows for recalculation of nodes in [TIS]Editor).
As in the Recalculate operator a Parameter was selected, this Parameter (and other selected Parameters) is/are visible in the Portlet.
