Recently a question on the OTN JDeveloper & ADF Space caught my interest. The question was how to initialize an af:quickQuery component with a parameter passed to a task flow on load of a page.
At first I thought that this would be a simple case of setting a property (InitialQueryOverwritten=true) as mentioned by Frank Nimphius in his article How-to query af:quickQuery on page load ?, but after a short test it turned out, that this setting only executes the query but can’t be used to initialize the criteria.
This blog is about a solution to this problem. The question can be divided into two smaller problems to solve. The first is to pass a parameter to a bounded task flow and use the passed parameter in the bounded task flow. The second problem is to initialize a default query attribute of a af:quickQuery component and execute the query.
