cflogin question

[bowshock]

When I run the code below, I am seeing the 'not defined' message.  Why is that?

<cflogin>
      <cfloginuser name="x" Password = "y" roles="z">
</cflogin>

<cfif NOT IsDefined("cflogin")>
     not defined
</cfif>

When I dump the getauthuser() variable, I see "x", which is expected.

No, you're not seeing things, @bowshock. I infact noticed something similar with cflogin some days ago. But I put it aside, as I was busy with other matters.

It appears to be a bug. I am curious what the ColdFusion Team makes of it: https://tracker.adobe.com/#/view/CF-4213180

I have added a comment to the bug report. It reads:

The following code works. cflogin is dumped as a structure containing the keys "name" and "password".

<cfform> 
<cfinput name="j_username" value="me"> 
<cfinput name="j_password" value="myPW"> 
<cfinput name="sbmt" value="send" type="submit" > 
</cfform> 

<cfif isDefined("form.j_username") and isDefined("form.j_password")> 
    <cflogin> 
        <cfloginuser name="#form.j_username#" Password = "#form.j_password#" roles="myRole">
        <cfdump var="#cflogin#" > 
    </cflogin> 
</cfif> 

<!---Cfscript version also works ---> 
<!--- 
<cfscript> 
if (isDefined("form.j_username") and isDefined("form.j_password")) { 
    cflogin() { 
        cfloginuser(name="#form.j_username#", password="#form.j_password#", roles="myRole");
        writedump(cflogin); 
    } 
} 
</cfscript>

 If that is indeed cflogin's intended usage, then the documentation should emphasize:

1.  the exact conditions in which the cflogin structure will be available;
2.  the fact that the cflogin structure will then be available only within the cflogin tag or function.

In the above code, you could of course do away with form submission. The code would then simplify to:

<cfset form.j_username="me">
<cfset form.j_password="myPW">

<cflogin>
    <cfloginuser name="#form.j_username#" Password = "#form.j_password#" roles="myRole">
    <cfdump var="#cflogin#" label="cflogin">
</cflogin>

<!--- alternative --->
<!---
<cfscript>
form.j_username="me";
form.j_password="myPW";

cflogin() {
    cfloginuser(name="#form.j_username#", password="#form.j_password#", roles="myRole");
    writedump(var=cflogin, label="cflogin");
}
</cfscript>
