[LON-CAPA-users] Number of bubbles for randomized exam

The resource does not need to be in a course if you include the  
numbubbles parameter in the problem, e.g.,

<parameter name="numbubbles" id="12" type="int_pos" default="4"  
description="Number of bubbles in exam mode" />

and publish the problem.

Thereafter when you view either the published resource or the resource  
in Construction Space you will see the number of bubbles displayed.   
My experience was that the value for numbubbles was not interpolated  
into the display within Construction Space until after publication.
