Element ARRAYROLES is undefined in a CFML structure referenced as part of an expression.

Here's my code:

<cfif StructKeyExists(cfData.data, "inherited_roles") || IsArray(cfData.data.reader_roles)>
  <cfset arrayRoles = "reader_roles" >
  <cfif ArrayIsEmpty(cfData.data.inherited_roles)>
  <cfset arrayRoles = "inherited_roles" >
  </cfif>
  <cfloop index="p" from="1" to="#arrayLen(cfData.data.arrayRoles)#">
     <!---some code here--->
  </cfloop>
</cfif>

And here's the error I kept getting.

Element ARRAYROLES is undefined in a CFML structure referenced as part of an expression.

The error occurred on line 07 when I have the #arrayLen(cfData.data.arrayRoles)#.

Any suggestion is much appreciated

    I even tried this <cfif #arrayLen(cfData.data.reader_roles)# lte 0 > and it error out as well.

    Error in custom script module


    Okay, I think I got it working now.

    <cfif not len(cfData.data.reader_roles)>
        <cfset arrayRoles = cfData.data.inherited_roles >
      <cfelse>
         <cfset arrayRoles = cfData.data.reader_roles >
      </cfif>
      <cfloop index="p" from="1" to="#arrayLen(arrayRoles)#">
      <!---code goes here--->
       </cfloop>

    Looks like the not len(cfData.data.reader_roles) do test if the array is empty or not. I'm not sure why the ArrayIsEmpty is not working in this case.

    The error is telling you the problem.

    Replace "arrayRoles" with "reader_roles" on line 7 and you won't get the error unless "cfData.data.reader_roles" is not an array, which could happen because of line 1.

    Perhaps you should explain what you are trying to achieve, perhaps there is a better way.

    Cheers

    First of, line 4 should be: <cfif ArrayIsEmpty(cfData.data.reader_roles)>

    Okay, by default, I am setting the ​cfData.data to reader_roles in line 4. However, if reader_roles array is empty, then set the arrayRoles variable to inherited_roles.

    So in cfloop line 7, I want to loop through only the array that actually have some data in there. Another way would be to do an if-else statement and put all the codes in there but I was thinking that by simply swapping the "reader_roles" for "inherited_roles" and vice versa at the end of cfData.data would work but ColdFusion throws an error.

    You're assigning a string value to arrayRoles and then trying to use it as an array.

    Try the following instead (assuming both are indeed arrays):

    <cfif IsArray(cfData.data.inherited_roles) || IsArray(cfData.data.reader_roles)>  

      <cfif ArrayIsEmpty(cfData.data.reader_roles)>  
        <cfset arrayRoles = cfData.data.inherited_roles >  
      <cfelse>
        <cfset arrayRoles = cfData.data.reader_roles >  
      </cfif> 
      <cfloop index="p" from="1" to="#arrayLen(arrayRoles)#">  
        <!---some code here--->  
      </cfloop> 
    </cfif>

    Cheers
