Hey Mark - this is pretty interesting. This is the first time I've

do - let me know and Ill link to it.

The struct is passed in from a Flash client using Flash Remoting.
Is it possible that the Struct has a null value against the key?
Yes, that could be possible in Flash to create a key assign it a null

Hi Chris
I've never quite understood why people use:
structFind(struct, key)
instead of just
struct[key]
?
I'm not sure if this would have any bearing on your issue

I'm not sure if this would have any bearing on your issue, but it
might be interesting to see the difference in behaviour.

If you try and output struct[key] and the key doesn't exists that it will
error
Sure. As with structFind().
Hence my question.
I think maybe you have confused the meaning of your message :)
Maybe. Or maybe... not.

I use StructFind() a lot - simply because I tend to encapsulate
struct's behind getter's and setters quite regualrly.
So Inside a CFC you would find me writing:
cfset thisValue = StructFind(getStruct(), key) /
As ColdFusion doesn't support syntax like:
cfset thisValue = getStruct()[key] /
I tried this (with CF8):
cfset myStruct = StructNew()/
cfset myStruct.key1 = Hello/
cfset myStruct.key2 = JavaCast(null, )/
cfset myStruct[key3] = JavaCast(null, )/
cfset myStruct.put( key4, JavaCast(null, ))/
cfoutput
Key1 Exists: #StructKeyExists(myStruct, key1)#br/
Key2

The reason being is that Java, as I see it when defining something as NULL
is telling you that it actually doesn't exist
Andrew, I beg to differ
for me NULL tells me that it has uninitialized memory
mayve try fully scoping the variable

I reckon it's the diff between the name of the structure and the

This generates an error.
It's not the StructKeyExists function that fails, it's the StructFind
and to make matters worse, it's intermittent.

yeah, I just realised... I actually meant not using the name the
structfind() but that won't help either.
cfset lvKEY = StructFind(pStruct, KEY)
anyhoo:
what do you get with
cfif StructKeyExists(pStruct,KEY) is true
cfoutput#StructKeyList(pStruct)#/cfoutput
is KEY in there
Hi Chris,
is the CFC you that is calling this is a shared scope? (EG:
Application scope)
The reason I ask is because in the past I have seen things like this
because of un-vared variables.
If two threads call the CFC at the same time, it can have odd results
and/or errors.
Just a thought...

I log a StructKeyList before the cfif and it's there.

It's not a cfc, it's a cfm with a function and it's called via Flash Remoting.

Chris,
I once had a pretty weird issue with dynamically created struct keys
that had invisible
whitespace-type special chars at the beginning/end of the string and had
similar error

a variable)
is trimmed and use the result
Chris - What is populating the Struct?

If there is a null value against the key, then it's quite likely that
the StructKeyExists will return true, but the StruftFind call will
fail as described.
