I'm thinking you found a bug related to how the action-createtiddler
handles the $template parameter.
In the meantime (i.e. until there is a fix or somebody can explain this
"feature" going on) ...
The following seems to work A-1 for me in my testing (ignore the "pre"
tags):
<pre>
<$button>
<$action-createtiddler
$basetitle="testTiddler"
$template={{{ [[BASENAME-]addsuffix{!!grammar_class}] }}} >
<$action-navigate $to=<<createTiddler-title>>/>
</$action-createtiddler>
create new test tiddler
</$button>
</pre>
