How to render the error portlet in an error page

[María Iriarte Ausejo, geändert vor 14 Jahren.]

Hello,
Is there any way to render the error "This portlet is not available" to an error page?

Sometimes we find these problems in our portlets, but the error only renders in the same portlet, however we would like to catch this error and show it in a personal error page.
Is it posible?

Thank you.
Regards.
