<cfscript>
// struct.find.cfm
st = {a="b",c="d"};
try {
	result = st.find("e");
}
catch (any e){
	writeDump([e.type,e.message,e.detail]);
}
</cfscript>

This outputs:
array
1	 Expression
2	 Cannot find e key in structure.
3	 The specified key, e, does not exist in the structure.

This should not ERROR if the "e" key is not found, it should just return something to indicate nothing was found. Probably null.

Compare with other find() functions... they just return a "it wasn't found" result.

This bug predates CF11, but as it impacts new functionality in the .find() method, I thought it was relevant to raise it now, during CF11 dev.

Comments:

strcut.find is implemented on top of StructFind functionality and its throw error for ages. Agreed that the structFind behavior is not completely correct but its not possible to correct now as it might cause major backward compatibility issue.

Changing the behavior of structFind() when the key is not present from exception to a null value will break backward compatibility. Existing applications might have coded to depend on such exception scenario.
