What is Interwindow Communication?
Interwindow Communication (IWC) is a frame to frame
messaging event which enables field change as they occur in the same browser
window e.g. communication between different pages. IWC can work in the same
pagelet or in different pagelets.Pagelet can work as subscriber or publisher for some other pagelet.
Business Benefits
- Allow pagelets to pagelet interaction with each other in Homepage/Dashboard,WorkCenter and Pivot Grid.
- No Application designer changes involved
- A business analyst can specify the fields required for using as subscriber or published
- Not dependent on Related Content, Workcenter or Integration Broker.
- Recruiters can create IWC pagelets for applicants - like updating the candidate status will immediately reflect in the dashboard.
- Managers can create IWC pagelets for employees. There will be no need to change the values again and again in different pagelets, for viewing employee data like employee absence request will immediately update the balances and can be seen on the dashboard.
Development Pre Requisites:
- Pagelets should be registered in the current portal system.
- Pivot grids should be published as pagelets.
- Get the HTML Field Name for Publishing and subscribing field.
As can be seen in the figure below the HTML Field Name is:
RECRUITER_ID.
Users can manually define the HTML field name of PeopleSoft
fields in Page Field Edit Box Properties- General Tab

IWC is ready for test.

Best Practices:
- While creating PS query with prompts, always provide unique text id.
- Provide page field name in edit box properties will make the work easier while configuring IWC.
Limitations:
- A subscribing pagelet should be completely loaded before it consumes a publishing message
- Works for fields at level zero only.
