[nodejs] Async KnewBee Question how to render after async.waterfall (node-mysql, zappa 0.4, express 3.0, CS)

[klrumpf]

I am trying to do some sync queries (node.mysql) and render the result. Zappa 0.4, Express 3.0, CS pr_art = [   { .etc etc   } ] ...   @post '/process': (req, res) ->  #PROCESSPROCESS-POST QUERY f.SHOWSTOCK     async.waterfall [(callback) ->       MysqlConnection = mysql.createConnection(mysql_options)       MysqlConnection.connect()       MysqlConnection.query sql, (err, rowcount) ->         ..do stuff....         MysqlConnection.end         callback null, rowcount     , (rowcount, callback) ->         MysqlConnection.connect()         MysqlConnection.query sql, (err, pr_art) ->           ...some more stuff...         callback null, pr_art     ], (err, pr_art) ->         @render showstock2: {           art: pr_art           artname: pr_art[0].artname             ....           } @view showstock2 ..... and I get "TypeError: Cannot call method 'render' of null or 'of undefined' If I do it with a '@redirect' to a '@get' that renders 'showstock2' it works seemingly but I understand that is not good practice and probably not safe under more load? Where do I think wrong and what's best practice for this sort of issue anyway?
