queryDataSource

public EODataSource queryDataSource()

Returns the receiver's EODataSource (defined in the EOControl Framework).

a datasource initialized with a qualifier that matches the search criteria the user specified in the query page. This datasource, for example, could be passed on to a List page to display the results.

setNextPageDelegate
