Haven't come across this issue before, but my guess would be that component parameters only accept certain data types. You could probably get around the issue by wrapping the values in a basic hashmap object.

<#attempt>
<#assign showSubject = (env.context.component.getParameter('customParams').showSubject) />
<#recover>
<#assign showSubject = true />
</#attempt>
<#attempt>
<#assign numReplies = env.context.component.getParameter('customParams').numReplies />
<#recover>
<#assign numReplies = 0 />
</#attempt>

I seem to get the same null/missing error when I try to pass the object. I tried assigning the object to a variable, and then accessing the object before I call the component, and that seems to work fine. Do you know if there's a way to create an XML object (or whatever kind of object is created by restadmin), as that seems to be the only kind of object I can pass, aside from a string.
