I have two portlets:

portletA – has modes VIEW and EDIT
portletB – has mode VIEW

In portletA's JSP, I'm using <liferay-portlet:renderURL portletName="portletB" portletMode="view" /> to create URL to portletB. If this JSP is used when portletA is in EDIT mode,
Result: Error is raised in log, saying:

17:12:09,792 ERROR [PortletResponseImpl:365] edit

This is caused by fact, that com.liferay.taglib.portlet.RenderURLTag.doTag()(method defined in ActionURLTag) first creates URL with portletMode retrieved from current portlet request:

LiferayPortletURL liferayPortletURL = _getLiferayPortletURL(
			request, plid, portletName, lifecycle);

In my case, it's portletA's request, having portletMode EDIT. This causes ERROR in log. As doTag() moves on, it sets portletMode to VIEW as defined in tag and URL is created and rendered in JSP correctly.

The only problem here is misleading ERROR in log, when there is no problem (my first idea when I spotted the error repeating in log was digging for some unsupported portletMode in portletB).
