Mohammed yasin:

This i think its not supported from Liferay 7 onwards, in 6.2 it was used for avoiding re-submission.

I'm assuming you mean com.liferay.portlet.action-url-redirect?

According to the documentation (https://portal.liferay.dev/docs/7-2/reference/-/knowledge_base/r/portlet-descriptor-to-osgi-service-property-map) it's still there, which points to it being supported - or a bug if it doesn't work.

In fact, the notation that Santosh B Biradar used, is the OSGi property notation (available since 7.0), not the 6.2 xml/dtd notation.

Hi,

we can use "com.liferay.portlet.action-url-redirect=true" property for avoiding re submission of form.

Hi ,
Instead setting the render parameter you create a render url and send redirect
PortletURL portletURL = PortletURLFactoryUtil.create(actionRequest, themeDisplay.getPortletDisplay().getId(), PortletRequest.RENDER_PHASE);
portletURL.setPortletMode(LiferayPortletMode.VIEW);
portletURL.setParameter("jspPage", "/pages/result.jsp");
actionResponse.sendRedirect(portletURL.toString());
