I have created a CFC object with these basic properties:
<cfproperty name="ID" type="numeric" default="0"> <cfproperty name="category" type="Category"> <cfproperty name="subcategory" type="string"> <cfproperty name="sscategory" type="SubSubCategory"> <cfproperty name="ladiesonly" type="boolean"> <cfproperty name="status" type="boolean">
With an init() method like this:
<cffunction name="init" access="public" output="false" returntype="struct">
<cfargument name="ID" type="numeric" default="0">
<cfscript>
instance = structNew();
instance.ID = 0;
instance.category = createobject('component','Category');
instance.subcategory = "";
instance.sscategory = createobject('component','SubSubCategory');
instance.ladiesonly = 0;
instance.status = 0;
</cfscript><cfif arguments.ID neq 0>
<cfquery name="subcat" maxrows="1" datasource="#application.config.DSN#">
select intBoutCatID as catID,
txtBoutSubCat as subcategory,
intSSCatID as sscatID,
blLadies as ladiesonly,
blActive as status
from tblboutsubcat
where intBoutSubCatID = <cfqueryparam value="#arguments.ID#" cfsqltype="cf_sql_integer">
</cfquery>
<cfif subcat.recordcount eq 1>
<cfscript>
instance.ID = arguments.ID;
instance.category = instance.category.get(subcat.catID);
instance.subcategory = subcat.subcategory;
instance.sscategory = instance.sscategory.get(subcat.sscatID);
instance.ladiesonly = subcat.ladiesonly;
instance.status = subcat.status;
</cfscript>
</cfif>
</cfif>
<cfreturn this> </cffunction>
As you can see two of the properties of the object are other custom objects (category and subsubcategory). I always thought this was possible, but I'm new at this so...
Anyway, I'm creating a backend editor for populating the db. In the "Edit" form, I create an instance like so:
<cfscript>
formSubCat = CreateObject("component","#application.config.CFCOMPONENTS_PREFIX#com.seacrets.boutique.subcategory").init(#url.id#);
</cfscript>
This does create the object. I am able to populate various fields of the form like this:
<input type="hidden" name="id" value="#htmleditformat(trim(formSubCat.getID()))#" />
My trouble comes when I try to access one of the object properties that is, itself, a custom object. For instance, I call a method to get the category object's ID:
<select class="boxes" name="category">
<option value="">-- --</option>
<cfoutput query="qCats">
<option value="#qCats.ID#"<cfif qCats.ID eq #trim(formSubCat.getCatID())#> selected</cfif>>#qCats.Name#</option>
</cfoutput>
</select>
This calls the following method in the subcategory CFC:
<cffunction name="getCatID" access="public" output="true" returntype="numeric">
<cfreturn instance.category.getID()>
</cffunction>
Now, in theory, this should be a no brainer, it should call the getID() method of the category object that is present in the current instance from the category CFC. However, I get the following error:
The selected method getID was not found.
Either there are no methods with the specified method name and argument types, or the method getID is overloaded with arguments types that ColdFusion can't decipher reliably. If this is a Java object and you verified that the method exists, you may need to use the javacast function to reduce ambiguity.
The error occurred in /home/httpd/seacrets/system/cfcomponents/com/seacrets/boutique/subcategory.cfc: line 162
Called from /home/httpd/seacrets/secure/editor/_subcat.cfm: line 260
Called from /home/httpd/seacrets/secure/editor/main.cfm: line 93
160 : </cffunction>
161 :
162 : <cffunction name="getCatID" access="public" output="true" returntype="numeric">
163 : <cfreturn instance.category.getID()>
164 : </cffunction>
...And then the stack trace stuff. Is this just not possible? Am I off my rocker here? If I can't do it this way then how should it be done?
