Displaying Data from a Data-centric Web Page with Sun Java Creator 2 - Connecting Table to Data
(Page 3 of 4 )
From the 2k5Java data source you will be displaying the data from the table called Argentina as shown in the following window, which shows the Servers window in the Sun Java Creator 2 IDE.
Now click on the table Argentina and click on the Table in the Design view of the web page. This changes the table column by bringing all the columns from the data source to the Table as shown. The rows in the design are just showing some data types, but not any from the data source.
The act of dropping the table object from the data source onto the Table control on the web page has altered the outline of the page as shown. It is possible to click on the table element in the Outline and view the corresponding item on the Design view. You also see that a "SessionBean" has been automatically created and the argentinaDataProvider has been added to the page.
Changes to page source code
The page content changes as the Table is added, and it gets bound by your action of dropping the data source onto the table. Here is an extracted content for the table alone in the source view. In addition to the data binding of the table columns with rows of retrieved data from the data source, you also see considerable script support in the [CDATA[...]] section for data filtering and so forth.
<ui:table augmentTitle="false" binding="#{Page1.table1}"
id="table1" style="height: 104px" title="Table" width="600">
<script><![CDATA[

var table = document.getElementById("form1:table1");
table.toggleTblePreferencesPanel();

function selectGroupRows(rowGroupId, selected) {
var table = document.getElementById("form1:table1");
table.selectGroupRows(rowGroupId, selected);
}

var disabled = (table.getAllSelectedRowsCount() > 0) ? false : true;
// Set disabled state for top actions document.getElementById("form1:
