Implementing AJAX Components in the JWL Framework
- Select the Panel Group and click Properties → AJAX. Click "Allow Ajax Updates" and set the Ajax request to "Refresh".
- Click the <hx:ajaxRefreshRequest> tag that was added in the Step 7 and add a parameter to be sent from the browser. The parameter is the input field that you added in Step 4: "text1".
- Drag and drop a Button Command and add a new behavior that will have "group1" target action and be invoked upon a mouse click.
- Run this JPS page on the server (make sure you are running under Websphere 6.1 or higher).
- When the page loads, enter a value into the input field and click the button. You will observe that the value that you had entered has appeared next to the button.
