cflogin - Struct cannot be cast
<cfif structKeyExists(form,"username")>
<cfset userLogin = application.admin.login(users_name=form.username,users_pass=form.password) />
<cfdump var="#userLogin#" label="user login data output" expand="no" />
<cfif len(userLogin.users_name) AND len(userLogin.users_pass)>
<cflogin idletimeout="1800">
<cfloginuser name = "#userLogin.users_name#" password ="#userLogin.users_pass#" roles = "#userLogin.users_admin#" />
</cflogin>
<cfelse>
<cfset invalid_login = 1>
</cfif>
</cfif>
The code (above) throws the following error:
Error casting an object of type coldfusion.runtime.Struct cannot be cast to coldfusion.runtime.Scope to an incompatible type. This usually indicates a programming error in Java, although it could also mean you have tried to use a foreign object in a different way than it was designed.
coldfusion.runtime.Struct cannot be cast to coldfusion.runtime.Scope
I can't for the life of me figure out why... Any help would be appreciated.

Look at the definition of the function "login" in your "admin" cfc... the return type is probably not STRUCT, but you are returning a structure. You can change the return type to "struct" or "any"
To be more specific, I was referring to this line...
<cffunction name="login" returnType="xxxxx" ....
<cffunction name="login" returnType="xxxxx" ....
> The code (above) throws the following error:
on which line ? can you include full error message?
> <cfdump var="#userLogin#" label="user login data output" expand="no" />
what type of object does application.admin.login return?

> <cfdump var="#userLogin#" label="user login data output" expand="no" />
what type of object does application.admin.login return?
Whoops... didn't see any responses before posting.

It's possible, but I'd expect a different error.

Function Being referenced:
I am not attempting to return anything, so I don't think that's it.
I thought that maybe it didn't like the directory structure. I rearranged that a bit, and still I get the same error. I am trying some other things now.
<!--------updateElement-(inception)------->
<cffunction name="updateElement" returntype="any" output="true" hint="updates data for products/services">

Brian - I think you posted the wrong function.

I'm mixing up my posts...
Hold one.

Here's the function:
<cffunction name="login" access="public" returntype="any" output="true" hint="returns login">
<cfargument name="users_name" required="yes" />
<cfargument name="users_pass" required="yes" />
<cfquery name="loginData" datasource="#this.dsn#">
SELECT users_name, users_pass, users_admin
FROM users
WHERE users_name = '#arguments.users_name#'
AND users_pass = '#arguments.users_pass#'
</cfquery>
<cfreturn loginData>
</cffunction>
ASKER
Here's the code:
<cfparam name="url.logout" default="0">
<cfparam name="invalid_login" default="0">
<cfif structKeyExists(form,"username")>
<cfset userLogin = application.admin.login(users_name=form.username,users_pass=form.password) />
<cfdump var="#userLogin#" label="user login data output" expand="no" />
<cfif len(userLogin.users_name) AND len(userLogin.users_pass)>
<cflogin idletimeout="1800">
<cfloginuser name = "#userLogin.users_name#" password ="#userLogin.users_pass#" roles = "#userLogin.users_admin#" />
</cflogin>
<cfelse>
<cfset invalid_login = 1>
</cfif>
</cfif>
<cfif url.logout>
<cflogout>
<cflocation url="index.cfm">
</cfif>
<cfif NOT len(GetAuthUser())>
<div class="loginForm">
<form name="userLogin" method="post" action="index.cfm">
<label for="username">User Name</label><input name="username" type="text" id="username">
<label for="password">Password</label><input name="password" type="text" id="password">
<input type="submit" name="login" value="Login">
</form>
</div>
<cfelse>
<p>User: <cfoutput>#GetAuthUser()#</cfoutput></p>
<a href="index.cfm?logout=1">Logout</a>
</cfif>
Works for me. Can you post the complete error message? It'd help to see the line number...

If I comment out the cflogin, there is no error.
Like So:
Like So:
<cfif len(userLogin.users_name) AND len(userLogin.users_pass)>

</cflogin>--->

I cannot. My host doesn't allow robust debug output.
ASKER
Output, the cfloginuser line looks like this:
cfloginuser name = "brian" password ="jesus" roles = "1"
> cfloginuser name = "brian" password ="jesus" roles = "1"
Does it work with a hard coded string instead of the query variables ? Maybe it's the query cflogin doesn't like.
> I cannot. My host doesn't allow robust debug output.
Wrap it in a try/catch then.
<cftry>
.... all of your code here
<cfcatch><cfdump var="#cfcatch#"></cfcatch>
</cftry>

I hard coded it, still get the error. I'll wrap it int the catch.

Hm... if it doesn't work with simple values then that suggests the cflogin code is wrong. Not sure. I rarely use cflogin ...

I copied and pasted it directly from Adobe's documentation. I think it's something on the server (settings). We'll see.
Could be. Sorry, I don't use cflogin. So I'm out of suggestions unfortunately.
ASKER
No worries. I have the admin's looking at the server. I'll post if that turns out to be the case.
I also don't use cflogin... so here's a very easy alternative.
Just set a session variable:
<cfset session.login.user_id = userLogin.user_id>
<cfset session.login.userName = userLogin.userName>
That's all you have to do..
Check to see if it's not populated and send the user to login...
<cfif NOT isDefined("session.login.u
.... login
</cfif>
I never userstood what cflogin provided that a few simple lines of code do not... except the cflogin stuff tends to mysteriously not work every now and then and there's no debugging it...
ASKER
That's usually what I do, I just wanted to try cflogin out. It's no wonder why no one uses it... Way to go Adobe! lol

But don't we all need a little mystery in our lives every now and then? ;-)

No. No we do not. I'd prefer things work they way they are supposed to. First time, and every time... Which is more of a fantasy???

The verdict.... scrap all attempts to use cflogin
ColdFusion Language
ColdFusion is a server-side rapid application development platform originally created by Allaire and now sold by Adobe, implementing the dynamic general purpose CFML programming language. The term ColdFusion is sometimes colloquially used to refer to the CFML language (Cold Fusion Markup Language), but can also include discussions of the server software implementation. ColdFusion runs using a customised version of Apache Tomcat. Earlier versions are bundled with JRun.
