For those that are interested, here's another test:
I changed the previous CFC to return an array of structures, with each
member of the array defined as a reference to the same structure.
When called, the returned arrays behave as expected: Each array
member contains pointers to the same structure, but each array has
its own structure created (separate calls to the CFC method).
Here's the code:
============ Start testComponent.cfc ==============
<cfcomponent displayname="myTest">
<cffunction name="getArray">
<cfset myStruct = structNew()>
<cfscript>
myStruct.first = "John";
myStruct.last = "Public";
</cfscript>
<cfset myArray = arrayNew(1)>
<cfloop from="1" to="4" index="i">
<cfset myArray[i] = myStruct>
</cfloop>
<cfreturn myArray>
</cffunction>
</cfcomponent>
============ End testComponent.cfc ==============
And the test:
============ start tst_testComponent.cfm ===========
<cfscript>
myObj = createObject("component", "test.testComponent");
</cfscript>
<cfloop from="1" to="2" index="j">
<cfset "request.thisArray#j#" = myObj.getArray()>
</cfloop>
<cfset request.thisArray2[1].first = "foo">
<cfdump var="#request.thisArray1#">
<cfdump var="#request.thisArray2#">
============ start tst_testComponent.cfm ===========
What this does to help solve the original question, I have no idea, but
maybe it'll help somebody... ;)
