ADF 11g : Label Modifications and Persisting Resource Bundle Changes
0Recently my colleague Lucas and discussed database based resource bundles and customization. This reminded me of a comment on one of my posts on the AMIS technology blog where I had a question on UIComponents. The question was if it is possible to modify prompts and labels of components programmatically. As a matter of fact this is possible. You can do this for the session only, or you can choose to persist these changes. In this post I first explain how to implement the “session only” functionality, and in the second part I explain how to use a persisted resource bundle with immediate refresh.
Application Setup
The application used in this post is based on the HR schema and the business components are created and not changed.
ADF 11g: Programmatically repositioning columns in a Rich Table
1Rich Tables are powerful beasts in ADF Faces. They can present tons of information in many different ways. They allow users an extensive range of manipulation – from reordering and hiding columns, changing column width to sorting and filtering the data presented in the table and detaching the table from its embedding page as well as exporting the data from the table to an Excel file. Pretty impressive. And many of the visual configurations can be stored using Change Persistence across requests and even across sessions.
One specific requirement on a recent ADF 11g project led me to investigating if and how the ordering of columns in a rich table can be manipulated programmatically (rather than having the user to it). Earlier articles on this blog discussed similar challenges: intercepting changes in the column order applied by a user (http://technology.amis.nl/2012/02/intercepting-user-customization-such-as-column-reordering-in-tables-in-adf-11g-change-persistence/) and programmatically setting the sort order for columns in a Rich Table (http://technology.amis.nl/2012/03/adf-11g-programmatically-configuring-sort-for-rich-table/). As in these cases, the solution turns out to be More >
ADF 11g: programmatically configuring sort for rich table
1A recent requirement on one of our ADF 11g projects: we want to gather a number of settings a user has applied to the rich table in one of the pages. These settings include position, width and visibility of columns (supported by change persistence) and custom data filter, sort configuration and highlight condition. These latter settings are not part of change persistence out of the box. An additional requirement is that this collection of settings is to be saved under a label and to be made available to all users for selection when they view that same table.
I like these requirements. They are tangible, concrete and add fun(ctionality) to the application that directly pleases the end users. With ADF 11g, it is not an extremely difficult requirement – it seems.
One of the aspects mentioned here – sort setting – requires us not only to intercept or capture changes in sort settings – which sortListener on the columns of the table will do nicely – but also the programmatic application of sort settings when the table is rendered and a ‘user saved packet of table settings’ is selected.
In this article I take a very brief look at how to programmatical set the sorting condition on the More >
ADF 11g : Fancy Master Detail or how to Highlight Related Detail Records
2Last week I a had a rather interesting question: Is it possible to highlight related data that is in different af:table components ? Sure you can, so I decided to write a simple example application, and share the knowledge in this post (more…)
ADF 11g : Query Component with 'dynamic' view criteria
0In my current project use a lot of re usable taskflows. In one particular situation I needed exactly the same taskflow to be re-used with one tiny small difference: The displayed query component needed to have different fields compared to page in the base taskflow. Now there are lots of possible solutions (two query components and a switcher, or two query components using the rendered property). I choose a different solution using ternary operator and EL in the page definition (more…)
ADF 11g Rich Faces: using popup for viewing and editing big fields
4During the Oracle Open World conference going on this week I was asked by one of the attendees to one of my sessions for a little guidance on the following challenge in ADF:
“We currently have an Oracle Forms application that we are rebuilding in ADF 11g. One of the features in this Forms application, is that whenever a field can contain a really large block of text, it will automatically be shown in a popup when the user clicks on or otherwise enters the field. Inside the popup, the entire field and its contents can be shown. Could you show me how to do this in ADF 11g?”
And that is a type of question I quite like. It is tangible, it is something I can easily help out with and by doing so promote ADF a little. So here it goes.
