Portlet Prepresentation

When using Portlet Prepresentation, you can add Prepresentation Begin and End delimiters using the Add Block Delimiter button on the Actions tab.

This action is not supported for HATS standard portlets.

The Prepresentation Begin and End allow you to enclose actions that must be performed in the prepresentation phase of portlet processing. Use the Add Block Delimiter button when implementing portlet messaging or cooperative portlets. Click the Add Block Delimiter button once to insert the prepresentation begin delimiter and click Add Block Delimiter again to insert the prepresentation end delimiter. Use the Up and Down buttons to move the action needing execution in the block delimiter higher or lower in the list. When the action needs to be invoked will determine the location of the prepresentation block. When executing a screen event, you can trigger the prepresentation action first or at the top of the Actions list. If you want to run the prepresentation action after user interaction on the screen, you would trigger the event at the bottom of the Actions list. For more information about how to use the block delimiter with portlets, see the Programming in HATS Portlets.
