In my current GAE project I have setup a BaseBean.cfc class that contains
the following method:
---------------------------------------------------------------------------------
<cffunction name="toStruct" output="false">
<cfset var result = {} />
<cfset var key = "" />
<cfloop collection="#variables#" item="key">
<cfif NOT
listFindNoCase("this,init,onmissingmethod,tostruct,tostring,googlewrite,googledelete,googlekey",
key)>
<cfset result[key] = variables[key] />
<cfelseif lCase(key) EQ "googlekey">
<cfset result["__key__"] = googleKey(this).toString() />
</cfif>
</cfloop>
<cfreturn result />
</cffunction>
---------------------------------------------------------------------------------
I then have created a few components that extend from this CFC, and in the
previous GAE version I was able to call this to get a struct version of the
component. The line "<cfset result["__key__"] = googleKey(this).toString()
/>" actually used to read "<cfset result["__key__"] =
this.googleKey().toString() />", but that started to throw errors, so I
switched in an effort to try to get something to work again. Either way,
both methods in the current 1.5b build return this error: "*The page you
were executing caused an internal BlueDragon server error*". Here is the
stack trace:
