[transfer-dev] invalid call of the function init, second Argument (UTILITY) is of invalid type, can't cast Object type [Struct] to a value of type [transfer.com.util.Utility]

Jim Rising Tue, 14 Jul 2009 10:23:23 -0700

I'm fairly new to transfer, have been evaluating it for a project at
work... and ran into this error while trying to create a ManyToMany
relationship. Any help would be appreciated! :)

Table schema:

User
user.UserID
user.username
user.password
etc...

Group
group.GroupID
group.name
etc...

mapgroups_users
mapgroups_users.usersID
mapgroups_users.groupsID
etc...

ManyToMany in transfer.xml.cfm:

<manytomany name="groups" table="mapgroups_users">
<link to="user.User" column="userID"/>
<link to="group.Group" column="groupID"/>
<collection type="struct">
<key property="groupID"/>
</collection>
</manytomany>

I do not have a transfer object defined for mapgroups_users ... per
recommendation from Ray Camden.

the related event:

user.dspEditUser:

<cffunction name="dspEditUser" access="public" returntype="void"
output="false">
<cfargument name="Event" type="coldbox.system.beans.requestContext">
<cfset var rc = Event.getCollection() />
<!--- No user object in Event Collection? (Will exist after
validation) --->
<cfif not isDefined("rc.user")>
<cfset rc.user = getPlugin("ioc").getBean("UserManager").getUser
( Event.getValue("userId","") ) />
</cfif>
<!--- EXIT EVENT HANDLERS: --->
<cfset rc.xehSave = "user.doSaveUser">
<cfset rc.xehBack = "user.dspUsers"> </cffunction>

&lt;cfset Event.setView("user/edit")&gt;

the related userManager

<cffunction name="getUser" access="public"
returntype="transfer.com.TransferObject">
<cfargument name="userId" type="string" required="false" default="0">
</cffunction>

&lt;cfset var user = ""&gt;

&lt;!--- Read user from DB? ---&gt;

&lt;cfif isNumeric(arguments.userId) AND arguments.userId neq 0&gt;

    &lt;cfdump var="#getTransfer().list("user.User")#"
label="getTransfer"&gt;

    &lt;cfset user = getTransfer().get("user.User", arguments.userId)
&gt;

    &lt;!---&gt;

    &lt;cfset groups = user.getGroupArray()&gt;

    --->

&lt;cfelse&gt;

&lt;cfdump var="else"&gt;

    &lt;cfset user = getTransfer().new("user.User")&gt;

&lt;/cfif&gt;

&lt;cfreturn user&gt;

It's definitely something related to the manyToMany relationship, as
when it is removed, the error does not persist.
