How-to Refresh a Bound Taskflow that is added as a Region to an ADF Faces RC Page and that is displayed in a Popup Dialog
Thursday, May 29th, 2008Every technology seems to have its superstar; a feature that developers love and use more than any other feature. Though in ADF Faces RC, there seem to be more than one super star feature, the clear winner of Oracle ADF Faces RC pop idol feature contest is a bound taskflow that is added to a [...]
Forum patterns: The problem of surfing on other people’s thread
Wednesday, May 28th, 2008Though not a frequent pattern on public forums, but one that exists: The “surfing on other people’s thread” pattern describes a post of a different subject than the subject handled in the thread it gets appended to. Mostly the appending forum user is not the same as the thread owner. The motivation users have to [...]
ADF Faces RC Declarative Components: How-to build them and how to bind them to ADF and PPR
Monday, May 26th, 2008Declarative components are reusable UI components that are declarative composites of existing ADF Faces Rich Client components. Using declarative components in JDeveloper 11, application developers can build their own components from one to many existing JavaServer Faces components. Usecases for which declarative components make sense include special layout definitions built out of nested existing layout [...]
ADF Faces: How-to reset the sort criteria on a sortable table
Wednesday, May 21st, 2008Tables in ADF Faces allow the users to sort the table values by a click onto the column header, assuming sorting has been enabled upon table creation or later configured for the columns.

Forum patterns: The problem of posting to the wrong forum
Monday, May 19th, 2008A while back I wrote about the "lost usecase" anti-pattern for questions asked on public forums. Seems that there are many more of those anti-patterns that are worth to discover and document.
In this blog I like to talk a bit about the problem of posting to the wrong forum. I bet all of us have [...]
Blogbuster Treasures Hunt: Blog entries from the lost Orablogs blog for download
Friday, May 16th, 2008Nikolay Smirnov is not only a frequent reader of my blogging, but also turned out to be a collector of its content. As if he knew what would happen to orablogs, he kept on copy and pasting the blog content to a Word document since 2006. The document became big and has the quality of [...]
ADF Faces: Suppress Validation on PPR request
Wednesday, May 7th, 2008Another lost sample from orablogs for self study. The workspace contains code that suppresses ADF validation if the request is from partial page rendering. Note that this uses an internal API. A public API is available in Jdeveloper 11 in where we use Trinidad.

ADF Faces RC: How-to configure a custom Splash Screen
Wednesday, May 7th, 2008Splash screens, or enduser entertainment as I like to put it, show at the beginning of initial page loading until all resources become available for the user to start his work. ADF Faces RC components provide a splash screen that by default shows a rotating "O" for Oracle with an associated message letting the user [...]
ADF Faces: ADF Faces Tree Drilldown Example
Friday, May 2nd, 2008Another lost example: The workspace linked by this blog entry shows how to use a command link to drill down to detail records shown in a table.
The drilldown functionality - though not shown as a stand alone example - is documented by Steve Muench in the context of the ADF BC version in the SRDemo [...]
