Marc,
I'm not entirely clear as to where things stand for you at this point
-- you sent a message about 24 hours ago that seemed to state you had
sorted out the onSessionStart issue, but then this latest message
appears to indicate that there is still a problem (specifically, the
"if it's not being triggered by CF's
> implicit event - onSessionStart" portion). Is this working for you?
>From this latest message, I think that there is a bit of confusion as
to how CF's application lifecycle events are handled by Model-Glue. I
would recommend going with the simplest approach here, which is to
define a message-listener in your XML config, along with a
corresponding function in your controller.
The message-listener should look like this:
<message-listener message="onSessionStart" function="onSessionStart" />
Or if you prefer, you can omit the "function" attribute, as it is
optional if the function name is the same as the message name:
<message-listener message="onSessionStart" />
Then in your controller, your function should be named "onSessionStart":
<cffunction name="onSessionStart" access="public" output="false">
It is important that you do NOT alter the onSessionStart function in
Application.cfc (the same goes for onSessionEnd) -- it should look
like this:
<cffunction name="onSessionStart" output="false">
<!--- Set flag letting MG know it needs to broadcast onSessionStart
before onRequestStart --->
<cfset request._modelglue.bootstrap.sessionStart = true />
</cffunction>
(In the original version, there is a call to the invokeSessionEvent
function that is commented out -- you do not need this for normal
usage of the onSessionStart event.)
You do NOT need to define a modelglue.onSessionStart event-handler in
order for this to work. As a matter of fact, if you do define this
event-handler, you must also define the onSessionStart message within
it -- otherwise, this message will not be broadcast, as you will be
replacing the internal modelglue.onSessionStart event-handler with
your version, and therefore its message broadcast will not occur.
Finally, I wanted to mention a couple of things regarding the
controller code you posted. First, these lines should not be in your
controller:
<!--- Set flag letting MG know it needs to broadcast onSessionStart
before onRequestStart --->
<cfset request._modelglue.bootstrap.sessionStart = true />
As I mentioned above, this code needs to be in the onSessionStart
function of Application.cfc, and it does serve any purpose in the
onSessionStart function of a controller.
Also, I would recommend using a different approach for accessing
services in controllers -- currently, you have this:
<cfset
localData.utilityService=APPLICATION["_modelglue"].getBean("UtilityService")>
In Model-Glue 3, the best practice is to use the "beans" scope for
this task -- please see this wiki page for details:
http://docs.model-glue.com/wiki/HowTos/HowToUseBeanInjection
After adding the UtilityService bean to the controller's XML config or
metadata, you can reference the service like so:
<cfset session.locale = beans.UtilityService.convertAccLanToLocale()>
Although this would be my strong recommendation, if you want to use
the getBean() method instead, then I would definitely suggest using
the getModelGlue() method to retrieve the framework rather than a
direct reference to the application scope:
<cfset localData.utilityService = getModelGlue().getBean("UtilityService")>
Please let me know if any of this is unclear, or merits further explanation.
