How to specify parameters for a custom plugin

Situation:

I am attempting to use the CP_DataSplitter plugin. I am using a Put-Context-Var to specify the splitXPath and splitSize for the CP_DataSplitter activity, but the plugin is still attempting to use the default values. What is the correct way to specify the parameter values?

Solution:

This can be easily achieved by following the below steps. We have taken an example of over-riding a FileLocation variable you can similarly use it for sourceXPath and splitSize variables.

1. We have created a variable "TestVar" in the table and defined it in the CustomPlugin with service.getValueByName("TestVar").
2. The value defined for "TestVar" in table is a variable named "FileLocation" that is written as $$FileLocation$$. 

4. Go to Process Flow Designer and use Put Context Var activity in it.
5. Create a new context variable and provide Variable Name as "FileLocation" and the value that you want to set for that variable.
