Previously I have posted about using dvt:thematicMap to mark locations using latitude and longitude, In that post I have described about showing different cities as markers on a world map using a POJO based data structure
Now In this post I am going to describe that how can we enable selection in thematic map and get selected location value in managed bean so here in this post I am extending that previous application
dvt:thematicMap looks like this after pointing cities markers

Now to enable selection set selection mode to single for dvt:pointDataLayer and create a selection listener method in managed bean. Read the complete article here.

This post is about showing a chart inside  ADF Faces Collection component like af:table or af:listView
This is a simple task to create normal chart but in case if we have to show table row record as a chart or graph then we have to change chart value and chart item value references so that it doesn’t show all record but only values of that row
This post talks about these two requirements
1. Show same viewObject values as chart in af:table or af:listView
2. Show child viewObject values as chart in af:table or af:listView
For First Case I am using a query based viewObject that has Department wise Minimum, Maximum and Average Salary and using this viewObject I’ll create a list view and graph in it Read the complete article here.

Previously I have posted about defining custom selection listener for af:table and perform desired operation on selection event of table row

Selection Listener is fired when server receives a selection event from client means whenever user selects a row in table (Selection Event) then server process that event and execute selection listener defined in managed bean

And this post is about creating selection event programmatically without user interaction with table.

In ADF we can queue ActionEvent , ValueChangeEvent and in same manner we can create and queue SelectionEvent programmatically

So for this I have Created a Fusion Web Application and prepared model using Departments table of HR Schema

Dropped Departments ViewObject on page as af:table and defined custom selection listener of af:table in managed bean. Read the complete article here.
