Custom Component Process on Load

I have a custom node that I have built that has a Value Select Configuration node in it. I feed the Value Selectoin Configuration values using a Table Creator node. The problem I have is that when this node is added to a workflow, it does not automatically load the drop down list from the Value Select Configuration. It requires the user to run the node once to populate the list.

How can I get the list in the configuration to load automatically when the node is dragged onto the workflow?
