Re: Array error

FreeMarker can't modify arrays (or List-s or Map-s). However your
example FTL could be rewritten as:

  <#assign colItems=[
    parameters.colItem1?1,
    parameters.colItem2?1,
    parameters.colItem3?1]>

Note that it can concatenate two sequences (array or List) though,
however if you do a lot (tens or rather hundreds) of such
concatenations, the resulting sequence will have a big access time.
