onRequestStart onRequest variable assignments
This application I inherited, certain variables are not persisting their values between onRequestStart and onRequest. I've been writing to a log file to document the changes. Seems to be happening just after onRequestStart ends and onRequest begins. Values are being reset. So the variables themselves still exist, just their value is being altered and I cannot see where it is happening. am I missing something obvious? ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:359891 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
RE: onRequestStart onRequest variable assignments
Don, You state that certain variables are being reset so then I assume that others are maintaining their values? Is there any difference in scope between those that are maintaining their values and those that are not? Is there a conditional redirect happening in OnRequestStart?

How to Determine CFC Method Called From OnRequestStart?
I'm currently trying to add logging to a webservice I've created. I'm not crazy about numerous lines of cflog inside the webservice itself; it seemed that I should be able to put a single line in the application.cfc's OnRequestStart method (not OnRequest as that won't work for remote calls) and have any and all calls within the webservice covered. The first snag was that IsSOAPRequest() only seems to return true when INSIDE a cfc function. I ended up watching the cgi.HTTP_ACCEPT variable for soap+xml. With my simple examples this seems to give an indication of when I'm dealing with a web service call. The next problem, however, has me stumped. At a very minimum I want to record which cfc method is being called. I've got access to the target page in the arguments scope. I also haven't exhausted the possibilities of the getSoap() functions but, like the IsSoapRequest() I'm afraid it might just not be available in the OnRequestStartMethod(). Extra peachy keen if, based on an application debug variable, one could also record the parameters passed in. How does one find out what method is being called via a SOAP request on the OnRequestStart method?

Re: How to Determine CFC Method Called From OnRequestStart?
You could try to put the logging in one place in the webservice cfc; in the pseudo-constructor area. Since that's in the CFC, perhaps isSOAPRequest() will work there (too lazy to check). mxAjax / CFAjax docs and other useful articles: http://www.bifrost.com.au/blog/ 2009/7/11 Matthew Reinbold matthew.reinb...@voxpopdesign.com: I'm currently trying to add logging to a webservice I've created.

Same goes for session variables and some others. Whenever you're in doubt, dump the whole application scope on a page, like so: cfdump var=#application# Check it out and see what's there.

Re: onApplicationStart Vs onRequestStart
OnApplicationStart runs the first time ANY user hits your site. It's commonly used for setting application variables that rarely change. Things like datasources are a good place for that or initializing a ton of cfobjects. I commonly put a cfif statement in my onRequest event to reset the application variables. like this: cffunction name=OnRequest cfif isDefined(attributes.resetVars) cfset onApplicationStart()/ /cfif /cffunction That way if you can rerun the function from any request.

Hi Sherif, Welcome to the community. :) The onApplicationStart and onRequest start events are simply events which occur at a given time and aren't actually tied to any variable scopes, other than the fact that onApplicationStart executes immediately after the application scope is created. But you can do whatever you want to in that method. For example, you can create request variables in the onApplicationStart method, even though it executes before onRequestStart. So the lifespan of an application looks like this: 1. onApplicationStart 2. onSessionStart 3. onRequestStart 4. index.cfm 5. onRequestEnd 6. return to 3 (onRequestStart) and repeat 7. onSessionEnd - user timed out 8. return to 2 (onSessionStart) and repeat for other users 9. onApplicationEnd - application timed out 10. return to 1 (onApplicationStart) the next time the site is visited You can use application variables in index.cfm -- they need to be properly scoped, but if you set them in the onApplicationStart method they should be available. Your onApplicationStart method may not be executing if you haven't specified a name for your application. So your Application.cfc should look similar to this: cfcomponent cfset this.name = myapplication / cffunction name=onApplicationStart access=public cfset application.ds = myDataSource / /cffunction /cfcomponent You can also look to see what variables you have in your application scope from your index.cfm template by dumping the structure like this: cfdump var=#application# / hth -- s. isaac dealey ^ new epoch isn't it time for a change? ph: 781.769.0723 http://onTap.riaforge.org/blog ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:313193 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4

Re: onApplicationStart Vs onRequestStart
The whole point of putting variables into the application scope is to cache them so you don't have to set them on every request. The reason your variables didn't get set after you added new ones was that your application had already started; OnApplicationStart doesn't run on every request. mxAjax / CFAjax docs and other useful articles: http://www.bifrost.com.au/blog/ 2008/9/29 Sherif Abdou Oh Ok I found what the problem is, I guess my Varaibles in the onApplicationStart got cached, so when I sent it once, launched and then I added another Variables after launched again the application variables dont' get updated.

I read that article, and while I'm glad this turned out well for you, there seems to be a serious misunderstanding in the article about how Java garbage collection works in CF. The garbage collection doesn't run after every request, by default - and you wouldn't want it to, either. Garbage collection is an expensive operation. And just destroying the unwanted references in onRequestEnd.cfm or the onRequestEnd method in Application.cfc isn't going to change that - it just means that those variables will be immediately eligible for garbage collection whenever it runs, as long as those variables have no other references in the stack. This isn't a memory leak. Java will eventually reclaim and reallocate that memory. That said, I'm not sure what's different about using Request variables in this way, since they're just references like any other reference, and the values stored in the heap should be destroyed by the garbage collector the same way. Finally, if you're creating truly global site variables, why not just use the Application scope? That's what it's for, after all. You don't have to worry about the silly locking issues like you did with CF 5 and earlier. Of course, if things are working as they are, it's probably not worth changing now.

Re: setting page variables in onRequestStart
My only problem with Request scope is that its available _everywhere_. I understand you can be a good developer and not use it in your model or elsewhere but I still dislike the request scope for that reason. Being a person that is constantly working on framework and components to be used in my company I cherish encapsulation and request scope spits in the face of that. Sure Application and Session do too but they server a good purpose for carrying state so I like them :) I do like your point about global variables for the life of the request and being easy to differentiate between those and page variables. I am with Dave though maybe Application or Session would be a better place for that info? Just my 2 cents. Also check out what Sean did with Application.cfc in fusebox very clever to get around most of the limitations/issues with onRequest.

Re: setting page variables in onRequestStart
Err, how is it a 'pseudo-scope? The request scope is a real scope
(don't give it any confidence issues!) just as much as Variables. And
I'll repeat my earlier assertion - that maybe seeing Request.Foo will
help it stand out compared to Variables.goo.
;) You mis-read me (and I express badly). For example, MG3 has introduced
the 'helpers' 'pseudo-scope'. With this, you put all your UDFs in a folder
called helpers and the app automagically places them all in a variable
called helpers. So then, in your cfms, or even your cfcs (yuck), you could
do:
cfset result = helpers.stringUdfs.myStringFunction('foo')
So here, 'helpers' is sort of a 'pseudo-scope'. Sure, it's just a structure
in the variables scope that has collections of udfs as its keys, but I think
the 'pseudo-scope' is a good term for it. This is what I was trying to
recreate for Richard - but I failed to calculate the inability to set
anything in the variables scope in application.cfc (the 'global' variables
scope outside of the cfc that is).
The request scope is absolutely fine. However, in this case, we were putting
the collection of udfs in the application scope and then wanting to create a
'pseudo-scope' for them to avoid verbosity. If that isn't possible, then the
best place for them is just to stay in the application scope (logically
where they belong):
cfset result = application.helpers.myStringFunction('foo')
But yeh, I completely agree that variables should sit in the scopes where
they belong - but I also like the idea of creating 'pseudo-scopes' if it
readable to do so ;)

Re: setting page variables in onRequestStart
My only problem with Request scope is that its available _everywhere_. I understand you can be a good developer and not use it in your model or elsewhere but I still dislike the request scope for that reason. Being a person that is constantly working on framework and components to be used in my company I cherish encapsulation and request scope spits in the face of that. Sure Application and Session do too but they server a good purpose for carrying state so I like them :) I do like your point about global variables for the life of the request and being easy to differentiate between those and page variables. I am with Dave though maybe Application or Session would be a better place for that info? Just my 2 cents. I agree with you for most app building. However, I was recently tasked with building a pretty much flat site but where ColdFusion templating would be really useful. For this simple app, I just setup onRequestEnd.cfm to be the HTML template that outputted #request.header# for various page specific header tags (javascript, etc) and #request.body# for the main content. Each individual page would then just savecontent to request.body and possibly request.header to be outputted later in onRequestEnd.cfm. The request scope was the logical place for these variables. (I'm sure that onRequestEnd tactic must have been / is a common tactic - not claiming originality!)

Right, you can't do that. The variables scope in App.cfc isn't copied to the template. Unless you use onRequest. But that has some drawbacks as well. Why not simply simply use the Request scope?

Re: setting page variables in onRequestStart
Why not simply simply use the Request scope? Verbosity. The idea he is working on is doing something similar to the way MG3 creates the 'helper scope' for udfs. I think helpers.myUdf() is preferable to request.helpers.myUdf() though its all good. Clearly with MG, the helper/event/viewstate variables are setup outside of any cfcs and I hadn't figured that in the sample code I came up with (I still use application.cfm).

I'd argue that variables he is setting on - every- page request should be segregated for normal page variables. If I see request.siteURL for example, it flags it as a variable that is always available, as opposed to just 'X' for example.

Setting session param in onRequestStart
Hey all, Had an interesting conundrum today. I wanted to param a session variable in Application.cfc, so naturally I placed the cfparam name=session.myvar default=false in onSessionStart. I quickly realized that this does not catch people whose sessions are already in progress. Since we pretty much have sessions running on our production server 24/7, there is never a time when I could post the updated Application.cfc and not get a bunch of myvar not defined in session errors. Solutions would be to a) restart the server or otherwise end all sessions (not viable), b) use structKeyExists(session,mvar) anywhere the variable is used, or c) place the cfparam name=session.myvar in onRequestStart. I chose c) as it is the most DRY (Don't Repeat Yourself) to implement, but I'm wondering if it is bad practice to param a session variable in onRequestStart, or if other folks have been in a similar situation and done anything differently. -- Josh ~| ColdFusion is delivering applications solutions at at top companies around the world in government.

You are correct, REQUEST is a single-page persisting object. In only lasts for the duration of the page request and then is destroyed. SESSION and APPLICATION are cross-page persisting scopes.

Re: onRequestStart
How often does the variable need to be updated? OnRequestStart will execute prior to every page request. If it less frequent than that, I would recommend putting it in the application start. You can use onRequestStart to check to see if the variable needs to be updated in the application scope.

Thanks for that. I had hoped I could throw the exception back to Flash like it can be done from methods in other components :( I'm trying to make use of onError but I'm not sure it fits. How does this sound: I implemented onError, which now fires when I cfthrow from inside onRequestStart. In onError I can't detect anything about the error I threw because the error caught is the same Event Handler Exception.

Head scratcher... Ok, doing this: cffunction name=onRequestStart returnType=boolean output=true !--- Display our Site Header at top of every page --- cfinclude template=SiteHeader.cfm cfreturn true /cffunction If I have a link with variable like images.cfm?year=2005 This works exactly like it should. An image on the page will display correctly and the path is correct: dance-pictures/2005-BLine.jpg However, to help pages get indexed I've changed all my URL variables to to look like: images.cfm/year/2005 When I do that, view source looks OK on the page, but the path for the same image above is now showing as: images.cfm/year/dance-pictures/2005-BLine.jpg Which ain't right - it's including the full file name into the folder path. In fact, all paths on the page are now screwed and nothing displays correctly - so I just get an unstyled page of text and nothing else. If I retype images.cfm/year/2005 as images.cfm?year=2005 in the address bar, all is right with the world again... Ideas of a fix??

Re: onRequestStart problem with url variables
cffunction name=onRequestStart returnType=boolean output=true !--- Display our Site Header at top of every page --- cfinclude template=SiteHeader.cfm cfreturn true /cffunction images.cfm/year/2005 OK, I understand what it's doing - the onRequestStart is reading the images.cfm/year/2005 as a full link - so maybe my fix is to put my url decode script BEFORE the onRequestStart ... ~| Message: http://www.houseoffusion.com/lists.cfm/link=i:4:234402 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4 Donations Support: http://www.houseoffusion.com/tiny.cfm/54

RE: cfinclude from a template, or onRequestStart?
I don't see why you couldn't or wouldn't Well you certainly could, although I wouldn't. It is the kind of thing that may not be a problem now but could be a hassle later. As you describe in your first paragraph below, it's a hassle when suddenly you *don't* want that template wrapped around your content for a new page. I would generally only put things I *always* wanted in application.cfc/cfm. I couldn't guarantee that anything I was displaying would be *always* wanted, as I may want a different template for a popup page, or I may be delivering a different type of content such as XML. -Original Message- From: dave [mailto:[EMAIL PROTECTED] Sent: Wednesday, 9 November 2005 11:47 p.m. To: CF-Talk Subject: RE: cfinclude from a template, or onRequestStart?

RE: cfinclude from a template, or onRequestStart?
Well there is obviously good and bad to doing it either way. The worse thing so far for me is that some pages I dont want the header and footer or like when using a text editor it tries to load the header and footer into the textarea. But both of those are easily solved by chucking an app.cfc/cfm page in their directory and not having the headers/footers there. I'm sure if i was building a nasa site I wouldn't do it this way but small sites I see no harm and if you do decide to do the rss/xml thingy, it's easy enough to change.

I usually assemble my pages with a cfinclude header, menu, footer, etc. But I figured it might be better to include the header.cfm in onRequestStart, and footer.cfm in onRequestEnd to keep from spreading includes all over the place.

Re: cfinclude from a template, or onRequestStart?
Depends on who you ask. That is an easy way to handle headers and footers in a simple site, but it violates MVC principles, so if you are looking for a cleanly separated View, you shouldn't go that route. I generally don't bother with MVC for quick and dirty apps or mini-sites, but I use a framework for anything that I plan to maintain and possibly scale long-term. It doesn't even matter which framework, really, I just want something that separates the different elements of my app. I like Fusebox 3 with a cfc layer for the model, but it is always tempting in FB3 to pollute the fbx_switch file with stuff that doesn't belong there.
