StructKeyFind to mean that if a Struct contains another struct then it will
dive into that too, but it doesn't say it will scan Arrays. Given that, I
wouldn't expect a Struct that contained an Array that contained Structs to
be searched through the array and into the Struct below. But I could be
wrong.
At any rate, if you describe your data structure more clearly then you'll be
more likely to get an accurate answer.

Subject: StructFindKey - what's really possible?
I have been on the list for years but am a bit of a shy lurker. I wonder if
anyone can help with the following.
The CF docs say:
"StructFindKey - Searches recursively through a substructure of nested
arrays, structures, and other elements, for structures whose values match
the search key in the value parameter."
This sounds great, but when I tried it with a two dimensional array of
structures I couldn't get it to work as I thought it should from the top
level. Am I misunderstanding something? Does anyone know if it is possible
to use StructFindKey in a two dimensional array? Looks like I can't, but I
wish....
Thanks if someone can cast some light on this.

Test code follows:
<cfscript>
aErrors = Arraynew(1);
//Create arrays and structures
aTwoDimArrayOfStructs = ArrayNew(2);
for(i=1; i lte 5; i=i+1){
ArrayAppend(aTwoDimArrayOfStructs,ArrayNew(1));
iDim1=ArrayLen(aTwoDimArrayOfStructs);
for(j=1; j lte 3; j=j+1){
ArrayAppend(aTwoDimArrayOfStructs[iDim1],StructNew());
iDim2=ArrayLen(aTwoDimArrayOfStructs[iDim1]);
StructInsert(aTwoDimArrayOfStructs[iDim1][iDim2],"struct content
("&j&")",iDim1&"."&iDim2);
}
}
try{
aTestSTFK = StructFindKey(aTwoDimArrayOfStructs,"struct content (2)","all");
}
catch(Any excpt) {
excptMessage = excpt.Message & "<br /><br />";
ArrayAppend(aErrors,excptMessage);
}
try{
aTestSTFK_d1 = StructFindKey(aTwoDimArrayOfStructs[1],"struct content
(2)","all");
}
catch(Any excpt) {
excptMessage = excpt.Message & "<br /><br />";
ArrayAppend(aErrors,excptMessage);
}
try{
aTestSTFK_d2 = StructFindKey(aTwoDimArrayOfStructs[1][2],"struct content
(2)","all");
}
catch(Any excpt) {
excptMessage = excpt.Message & "<br /><br />";
ArrayAppend(aErrors,excptMessage);
}
</cfscript>
