Re: Odd behavior when using cfform inside a CFC
Unfortunately, I'm on a very tight self-imposed deadline, so I've dropped it for the time being and I'm skipping the cf8 ajax functions. I'll revisit in the next version. I did try moving the relevant CFCs to the request scope. Didn't do the trick. Even those I invoked the CFC fresh on every page visit, I only got the /cfide scripts on the first view. To get them back, I had to restart jrun. Not an optimal solution. I'm sure its something simple, but for the time being I'm just going to have to wait. I did find this discussion which seems to be a related/same issue, but specific to coldbox: http://www.luismajano.com/forums/index.cfm? event=ehMessages.dspMessages&threadid=626902EA-123F-6116-42A4A957FB64581 C On Sep 11, 2007, at 6:02 PM, Jaime Metcher wrote: > Not sure how much effort you want to go to, but if you want to have > it both > ways you could have a per-request object which has composed into it > the > session-scope object. > > Did you do that dump of the variables scope?

RE: Odd behavior when using cfform inside a CFC
Not sure how much effort you want to go to, but if you want to have it both ways you could have a per-request object which has composed into it the session-scope object. Did you do that dump of the variables scope? I'd be interested to see how CFGRID is doing this. I'd have a look myself, but my copy of CF8 is still in a box on my desk.

Re: Odd behavior when using cfform inside a CFC
This stands to reason, as the grid objects needs to know if the relevant JS has been included once already, in case you have multiple grids on a page (or any other controls using the same JS files). It seems that calling multiple grid tags reuses the same java object in a page (and in this case it's stored in the CFC instance).

Re: Odd behavior when using cfform inside a CFC
You could try dumping the variables scope of the CFC to see if cfform is putting something in there. But whatever the problem is, I'm pretty sure it must be related to the fact that the CFC is being stored in a shared scope. Does switching to a per-request CFC allow the JavaScript to work correctly? While I don't recommend doing it in general, you might also see if doing a cfinclude of a template that contains the cfform tags makes a difference.

Well, this really is just a wild guess, but maybe it's worth trying re-instantiating the CFC on every request. CFFORM could be stashing some state in that CFC.

Re: Odd behavior when using cfform inside a CFC
Jaime interesting question, and yes, the CFC in this case is stored in the session scope. Andrew ... for a lot of reasons, I chose to have the "view" layer implemented in a CFC. The application is set up such that a user creates their own templates, and then uses keywords inside those templates which are equivalent to various widgets, etc. For example, the user might put the following into their template, which is stored in the database: %title% other stuff some header and formatting stuff %blog_entry% some footer and formatting stuff All of the above is stored in the database. When the page is actually executed, the OnRequest in application CFC looks something like this: #APPLICATION.PG.RENDER(TEMPLATE, REQUEST.RQ)# So this calls a function that determines which of those templates to use, then renders it, calling the correct routines on the fly. So basically all of the content in any given user website is driven by the render method in the page processing CFC. I ended up building it this way because the app was a nightmarish chaos of code before. While I appreciate the suggestion to separate out the page processing into CFM templates, I've just spent about six months undoing that, so it's not really an option at this point. That said, the "view" CFCs are separated out from the business logic, but yes, it's completely CFC driven. I don't have any CFM templates in the entire app. > > Also, I know that was only pseudocode, but given that "var" is a > reserved > word it looks a bit dodgy.

RE: Odd behavior when using cfform inside a CFC
That is correct, CFC's are really used for business logic. Not that they can't be used for output, just that it makes for ugly coding in my opinion. Keep things simple and in their place, and it will make for easier debugging and maintenance further down the track. Andrew Scott Senior Coldfusion Developer Aegeon Pty.
