How to redirect from a Render Filter

[Jose Camallonga，修改在13 年前。]

Hi everybody,

I am doing a filter with a render and an action to check if a user is logged in.

When it's calling and action I can redirect him to the home page if it's not logged in with the method actionResponse.sendRedirect(...) but when it's calling a render I don't know how to do it.

Any ideas?


Thanks!


Jose

Hi, did you solve it?

I have the same problem. I have two portlets, and I passed parameters from portletA to portletB but, when I want to redirect to portletB to see results I dont know how... because the render in the portletA dont have a redirect method
.¿Anyone help me?

You can't send redirect from render phase. At the time your portlet is rendered there might already be content committed to the output stream by other portlets that's why the spec doesn't allow it. When action phase is execute it only targets it to one portlet and that's why you can do redirect from there.
