Message: No handler found for type: screen

Hi there, I swear that this code worked a few minutes ago and now it gets
me an error. I simply try to follow the document here
https://cwiki.apache.org/confluence/display/OFBIZ/OFBiz+Tutorial+-+A+Beginners+Development+Guide#OFBizTutorial-ABeginnersDevelopmentGuide-Part1and
the error shows up when I try to run the code done in part I. This is
the java console:

Re: Message: No handler found for type: screen

Administrator

You broke the screen handler
Message: No handler found for type: screen

Not sure how you did that, it's normally in common-controller.xml (also in ecommerce controller, the others you can neglect)
<handler name="screen" type="view" class="org.ofbiz.widget.screen.MacroScreenViewHandler"/>

Re: Message: No handler found for type: screen

Jacques, thank you for your response. I will look into it. I noticed that
it ran with no errors when I changed the handler to this in the
controller.xml:

<handler name="screenxml" type="view"
class="org.ofbiz.widget.screen.ScreenXmlViewHandler"/>

Re: Message: No handler found for type: screen

In reply to this post by Jacques Le Roux

Jacques, it looks like the common-controller.xml file located under
framework/common/webcommon already has a line with: <handler name="screen"
type="view" class="org.ofbiz.widget.screen.MacroScreenViewHandler"/>

Before changing things around you need to understand what you are doing, or is this part of the tuto?

Re: Message: No handler found for type: screen

Hi Jacques, I was not changing anything. I'm going through the tutorial and
it looks like it works when I remove the line with: <handler name="screen"
type="view" class="org.ofbiz.widget.screen.MacroScreenViewHandler"/> at
all. I guess it uses the default one defined somewhere earlier in the code.
