System portlet not rendering

[Amy Green, geändert vor 11 Jahren.]

I have created a System portlet similar to Chat Portlet that, like any other system portlet, appears in every page.
The problem is that I need it to be rendered everytime I change to another page, but it only renders when the page I'm going to has other portlets. If the page is empty, or has onl a webContent visor, the portlet doesn't go to the render method and although I'm showing another jsp in that momment, it shows the "view.jsp", which is the jsp rendered in the start.

What can I do to force a render of the portlet each time I change between pages?

Thank you
