Apache Trinidad Chart

[Chris Jurado, modifié il y a 12 années.]

Hey all,

Hello,

I’m working on a portlet using MyFaces and Trinidad. I have successfully created a working hello world portlet using:

Apache MyFaces 2.0
Apache PortletBridge 3.0
Apache Trinidad 2.0

The environment is

Liferay 6.0.6 running on Tomcat 6.0.29

The portlet installs and runs fine, displaying a simple outputText control, but the Trinidad Chart control doesn’t display. The value is set to a backing bean that is being instantiated (debug statement in the constructor outputs) but no graphical display.

My faces-config.xml:

I’m getting no errors of any kind, yet all I see in the portlet view is the value of the h:outputText, and the debug statement in my backing bean outputs, so at least I know everything else is working. I installed it as a stand alone app in a separate Tomcat and it worked great. I suspect it's a conflict with either the JavaScript in the component or maybe the images.

Any ideas? I can't be the only one to have faced this.
