 There’s a rather obscure JDeveloper bug that only effects IE7, for af:columns in af:tables that show af:outputText fields based on dates that are null (phew, try and say that with a mouth full of wheaties). It occurs in 11.1.1.4.0 and 11.1.2.0.0 (and all versions in between it’s assume...Nov. 23, 2011 05:00 AM EST Reads: 4,083 |
 Within JDev 11g+ experienced ADF programmers will be familiar with PageFlowScope beans used by tasks flows, in particular Bounded Task Flows (BTFs) where they provide the equivalent of session scope for variables for the life of the BTF for a specific user session.

 With the huge amount of sessions at Oracle Open World, it’s often hard to find the little gems of information amongst all the marketing.

 From time to time in JSF and ADF Faces RC applications there’s the need from one managed bean to retrieve another, typically from a lesser scoped bean to a greater, such as a requestScope bean retrieving a sessionScope bean to access its methods. There’s essentially 3 avenues to solvin...Sep. 21, 2011 03:30 PM EDT Reads: 6,474 |
