What you show here should work, however I doubt this was the template
that throw the above exception, as here in the last line you made the
whole types[...] stuff to be an unevaluated string. Anyway, what you
wanted in the last line is certainly this:

  <#assign uiType = types[annoType]>

No need for all the ${}-s and quotation marks. This should work as far
as annoType is either the string "TEXTBOX" or the string "SELECT".
