This is a known issue due to the way in which the regular expression
for element hash attributes. Basically the end of the "#{action}" is
being captured into the list of hash attributes. This then breaks
because there is an extra closing brace where HAML doesn't expect
there to be one.
The only work around at the moment is to avoid using the "#{action}"
string interpolation style when using a HAML element attribute hash.
You will either need to use
'string1' + string2
style of mixing strings, or I have added an alias for the
Ruby :sprintf method as just :s. So I would call
s("string1%s", string2)
which still doesn't look too bad.
Hope that helps,
Geoff
