Wiring two applications in lotus notes

I need to wire two applications so that one reacts when another is selected.

I need a calendar view (populated in one ap开发者_运维技巧plication) to update when a person is selected from a list (based from another application).

I have been trying to do this for absolutely ages and have hit a brick wall as the existing knowledge base is pretty poor. I don't understand how to compose the action required to do this, or how to use the WDSL system to wire the two, which i will be linking using the UNID of the person.

Any help appreciated.

Assuming you are using 8.x+. Look up this example in the designer help: Example 1 - Simple composite application creation using Lotus Notes components
