Hi Omi: I think you must have a error in this line:
result += "<option value='" + model.id + "'" Just because you are trying to concat a String with a Long. And not because the model.id is wrong. Try using str() function like this: result += "<option value='" + *str(*model.id*)* + "'> some text maybe showing id too:"+ *str(*model.id*)* +"</option>" or this one, more pythonic: result += "<option value='%s'> some text maybe showing id too:%s</option>" % (model.id, model.id) Another thing I use to do, is print variables that I'm using, just to see if is something wrong with it. I mean: print "model.id:", model.id result += "<option value='%s'> some text maybe showing id too:%s</option>" % (model.id, model.id) And watch the console where w2p is running, to see the output. HTH. Bye PS: doble check my code, maybe having a typo
