This comes up so much and the answer is on the ColdBox wiki and mention a
lot in these forums.
If you are getting this error and you have upgraded to ColdBox V3.0 M5/M6,
then you need to switch over to the new injects way of doing things.
So this
<cfproperty name="User" type="Model" scope="instance"/>
Now becomes
<cfproperty name="User" inject="model:user" />

I am using CBM6 on cf 8.1
No need to create the instance Struct. Its done automagically.

here is what I have updated the code to and I am still getting the
same error
<cfcomponent name="User" extends="coldbox.system.EventHandler"
output="false" autowire="true">
<!------------------------------------------- CONSTRUCTOR
-------------------------------------------->
<cfproperty name="UserModel" inject="Model:User" scope="instance"/>
<cffunction name="init" output="false" returntype="User">
<cfreturn this>
</cffunction>
<!----------------------------------------- IMPLICIT EVENTS
------------------------------------------>
<!------------------------------------------- PUBLIC EVENTS
------------------------------------------>
<cffunction name="ChkUser" access="public" returntype="any"
output="false">
<cfargument name="Event" type="any">
<cfscript>
var rc = Event.getCollection();
return instance.UserModel;
</cfscript>
</cffunction>
Hi, Chris:
I am *not* an expert on ColdBox, however, I think the problem is in your *inject* value.
1. I believe you should have the following in your /config/ModelMappings.cfm file:
addModelMapping(alias="User", path="UserService or whatever it is named in your /Model directory");
2. Then, in your *inject* value, you would simply have "Model", the name should be your alias, like:
<cfproperty name="User" inject="Model" scope="instance" />
Did I mention that I am NOT an expert?

no dice, i tried changing it to : <cfproperty name="User"
inject="Model"/>
my model is named User.cfc as well, so I would think this should work
Try
<cfproperty name="User"
inject="model"/>

both this:
<!------------------------------------------- CONSTRUCTOR
-------------------------------------------->
<cfproperty name="User"inject="model" scope="instance"/>
<cfscript>
instance=structNew();
</cfscript>
<cffunction name="init" output="false" returntype="User">
<cfreturn this>
</cffunction>
<!----------------------------------------- IMPLICIT EVENTS
------------------------------------------>
<!------------------------------------------- PUBLIC EVENTS
------------------------------------------>
<cffunction name="ChkUser" access="public" returntype="any"
output="false">
<cfargument name="Event" type="any">
<cfscript>
var rc = Event.getCollection();
//var UserModel=getModel('model.User').init();
//TestUser=UserModel.ChkUser();
//sUsername=rc.username,sPassword=rc.password
return instance.User;
</cfscript>
</cffunction>
or this:
<!------------------------------------------- CONSTRUCTOR
-------------------------------------------->
<cfproperty name="User"inject="model"/>
<cffunction name="init" output="false" returntype="User">
<cfreturn this>
</cffunction>
<!----------------------------------------- IMPLICIT EVENTS
------------------------------------------>
<!------------------------------------------- PUBLIC EVENTS
------------------------------------------>
<cffunction name="ChkUser" access="public" returntype="any"
output="false">
<cfargument name="Event" type="any">
<cfscript>
var rc = Event.getCollection();
//var UserModel=getModel('model.User').init();
//TestUser=UserModel.ChkUser();
//sUsername=rc.username,sPassword=rc.password
return User;
</cfscript>
</cffunction>
= the same problem
i think i may have found the problem, I was using this handy script to
dynamically add all of my models
<cfscript>
/**
* Deletes the n leftmost elements from the specified list.
* Modified by RCamden : objectivebias.com is coming soon
sorry for the multiple replies all, it appears it was the way that
script was setting up my model mappings that was screwing up
everything - now that I have removed the script and added my model
mappings manually the inject works like clockwork and I am refactoring
now
Is the name of your model User or UserModel? Depending on this you need that
with the model: declaration.
Also in CB 3.0 you don't need the autowire and extends anymore either, you
can still use them but they are not needed.

I don't see how it is handy, everything in the model directory is already
able to be used without this code.

<!--- Add model mappings dynamically for all cfcs found in the /model
directory ---> <cfdirectory action="list"
directory="#expandPath('/model')#"
name="files" recurse="true" />
<cfloop query="files">
<cfif right(files.name,4) is ".cfc">
<!--- rip extension off component --->
<cfset filename = left(files.name,len(files.name)-4)>
<cfset thisPath = listAppend(listDeleteLeft
(files.directory,listFindNoCase
(files.directory,"model","/"),"/")
,filename,"/") />
<cfset
addModelMapping(path=listChangeDelims(thisPath,".","/")) />
</cfif>
</cfloop>and it looks like this does not work right with CB 3.0
- it was pretty
handy
