I've been using the FlashMessage plugin in a few apps now, and it works for
me. The Flash message concept is implemented in every other language and
framework in exactly the same manner, the problem seems to be
implementation. If the plugin is dramatically altered, my apps will no
longer function as designed :( which sucks.

for your template problem, try ... <% flash( 'error', flash( 'error' ) ) %>
because your requirements are not normal use-case scenario. FlashMessage
should support array though.
