UninvocableEntityException: Puzzling ColdFusion Exception

So I'm calling a function in the same CFC, and I get the following error:

Entity has incorrect type for being called as a function.
The symbol you provided getProductColors is not the name of a function.

Intersting. The top of the stack trace reads:

coldfusion.runtime.CfJspPage$UninvocableEntityException: Entity has incorrect type for being called as a function.
   at coldfusion.runtime.CfJspPage._invokeUDF(CfJspPage.java:2441)
   at coldfusion.tagext.lang.InvokeTag.doEndTag(InvokeTag.java:432)
   at cfceilume2ecfc2110149128$funcSAMPLES.runFunction(D:\site\insideDev\com\ew\feed\ceilume.cfc:71)

While I have no idea why the error occurred, I was able to make the problem go away by modifying the name of the method I was calling, changing it from getProductColors to getProductColorList.

Strange. A Google Search only returned one result, so I thought I'd contribute a little info in case someone else finds the same error.

Ed's Gravatar My guess is that you've found some java method buried somewhere.

Sam Curren's Gravatar Interesting. I've found an undocumented reserved word? It fits.

This really surprises me. I've never hit a CF error this random and unexplainable before.

Edward Smith's Gravatar Had a spare moment and tried to reproduce this error on 8.01 64bit on OSX, and I was unable to reproduce it.

blah.cfc:
<cfcomponent output="false">
   <cffunction name="getProductColors">
      <cfreturn "I'm a function">
   </cffunction>
</cfcomponent>

blah.cfm:
<cfset toot = createObject("component","blah")>
<cfdump var="#toot.getProductColors()#">

spits out "I'm a function".

Edward Smith's Gravatar Oops, read it closer, but tried again, with no failure:

blah.cfc:

<cfcomponent output="false">
   <cffunction name="getProductColors">
      <cfreturn "I'm a function">
   </cffunction>

   <cffunction name="test">
      <cfreturn getProductColors()>
   </cffunction>
</cfcomponent>

blah.cfm:
<cfset toot = createObject("component","blah")>
<cfdump var="#toot.test()#">
