Developing
The topics in the Developing section describe tasks performed by an application developer.
Presentation layer
WebSphere Commerce uses Java Server Pages (JSP) to implement the view layer of the Model-View-Controller (MVC) design pattern. The view layer is in charge of retrieving data from the database through the use of data beans and formatting it to meet the display requirements. The view layers determines whether the request is sent to a browser or streamed out as XML. JSP files present a clean separation between data content and presentation.
Customizing IBM Sales Center
In the IBM Sales Center for WebSphere Commerce there is a set of user interface panels, views and dialogs that contain the most commonly used features. You can add to or configure the user interface to suit your needs, as well as changing the content and format of the data that is passed between the client and the server.
Controls
The layout of the IBM Sales Center dialogs and editors are constructed using configured controls. A configured control is a user interface element that is declared using the controls extension point. The definition of a configured control includes a unique identifier, the type of control, and additional attributes and properties that are specific to the type of control being defined. The control type is used to locate a control factory class that will construct the new configured control. Examples of control types include text, label, requiredLabel, combo, pushButton, checkBox, radioButton, table and composite. The complete list of controls is found in the extension point documentation.

Modifying a table definition

To modify a Sales Center table definition:

Procedure

Declare a new table definition using the com.ibm.commerce.telesales.widgets.tableDefinitions extension point.
-If you are adding columns to the end of the table definition, then you should use the referenceId attribute to specify the fully-qualified ID of the table definition that you are replacing. The table columns declared in the new definition will be appended to the end of the definition.
Optional: If you need to reorganize the table columns, then you should not use the referenceId attribute, but instead re-declare the entire definition. You can use the referenceId attribute on the column elements so you don't need to completely re-declare the columns.
After re-declaring the new table definition, use the system configurator to indicate that the new definition should be used instead of the Sales Center definition. Table definitions that refer to the removed table definition using the referenceId attribute will not be affected.

Results

Changing the default ordering sequence of a table column - By default a table is being sorted by it's first column in ascending sequence. If you need to change the default ordering sequence of table column in ascending or descending order, you can do that while defining the table. Set the initialSort attribute to true for a column for which you want to sort the table and then set the ordering sequence as ASC or DESC. Here, make sure that the table should have only one column for which the initialSort attribute is set to true. The same approach is also applicable to the existing tables while customizing them.
