#10 disabled facestraces thrown error with ui:debug

[Anonymous]

Having disabled facestraces 1.0.1 in JSF MyFaces 1.1.6,
I got error when pressed Ctrl-Shift-D (to display ui:debug)

<!-- Disable/Enable FacesTrace debug tool -->
<context-param>
<param-name>com.prime.facestrace.DISABLE_TRACE</param-name>
<param-value>true</param-value>
</context-param>

Error:
