Hi group - an admitted Mach-II newb here, I've come across something in my development that I'm not sure if it's a bug or a feature, so I wanted to see if I'm maybe doing it wrong.
We have inherited a couple Mach-II applications where every listener is defined as type EventArgsInvoker. In the process of trying to improve our usage of Mach-II and separate code out as much as possible, I have found the need to set an event-arg parameter from one of the listeners, so it could be used by the XML after the call. It is basically the only way I know of returning more than one piece of information from the listener (the other piece is already being returned via the resultArg). However, I tried to do this and I quickly realized that EventArgsInvoker does not actually pass in the event object to the listener. That is specifically the job of the alternative EventInvoker. So my question is this: is it possible to set a new event-arg in a listener that is of type EventArgsInvoker? I cannot find a way to do this; the event variable only contains the name of the event itself, not the object information. If not, does anyone think it would be a problem to pass in the event object as well as all event-args to that type of listener? I have modified the framework on my local instance to do just this, and it seems to solve my problem. I'm just wondering if there is a specific reason for not passing in that event object (memory, speed, etc). I understand that the recommendation is to use EventInvoker instead of EventArgsInvoker, but it really isn't an option for our site to switch to that (at least in the short term), as everything is already coded using an argument approach. Another alternative, maybe we could define another type (or set) of invokers which could use a "resultStruct" idea. That way, I could return a struct from my listener, and the invoker would loop over that struct and set the appropriate values based on their names. But maybe that is fundamentally wrong, as a function should by definition only return one thing. Anyway, anyone have any thoughts? -- To post to this group, send email to [email protected] For more options and to unsubscribe, visit this group at http://groups.google.com/group/mach-ii-for-coldfusion?hl=en SVN: http://svn.mach-ii.com/machii/ Wiki / Documentation / Tickets: http://trac.mach-ii.com/machii/
