Error Message Display
When a pagelet cannot be retrieved, an error message appears.
You can disable this error message. If the error is not displayed, then the pagelet disappears from the template without a message to the user.
To control the display of this error message, use the DisplayError attribute of the IClientComponent tag:
<IClientComponent Name="Example" DisplayError=false>
<Source Product="">http://www.InvalidServer/InvalidPage.html</Source>
</IClientComponent>If the portal servlet finds DisplayError equal to False, it does not display the error but adds the empty pagelet comment tags. If DisplayError is equal to True, or if the attribute is not found, the error message is displayed.
This feature works best when the HTML for the template can flow around the empty content properly.
