RE: JSON Encoding bug (again...)
Dave,
The code testval = '.0006' makes me think a string instead of a number.
Javacast might force a type on the string eh?
Brooke - are you looking for a number or a string?

Subject: Re: JSON Encoding bug (again...)
I have had to do so many hacks to get serializeJSON() to play nice. I add
a
~ to all yes/no strings so I don't get back true/false values, I have a
series of regular expressions that quote values in the resulting JSON that
don't get quoted and break on the client side. And now I have this issue:
cfset x = {testval='.0006'}
cfdump var=#serializeJSON(x)#
Which outputs:
{TESTVAL:6.0E-4}
WTF?
I am using CF 9,0,1,274733
Update Level /C:/ColdFusion9/lib/updates/hf901-4.jar
Anybody know of a workaround for this? The source data is in a query which
gets serialized after being converted to an array of structs. It would be
too slow to check each field for values like this and modify them to
return
to the client. I need another Idea. Anyone?
This isn't really a problem with JSON serialization, but with CF being
typeless, and CF's tendency to autoconvert numbers into scientific
notation. You can work around this by using precisionEvaluate(), the
BigDecimal version of the Evaluate function:
cfset x = {testval=precisionEvaluate(.0006)}
cfdump var=#serializeJSON(x)#
Note that this will add a leading zero.

That might work, but the problem is that CF will continually reevaluate values every time they're used - as you'd expect in a typeless language. All you can do is force CF to treat a variable as a specific type for the current operation. Here we have two operations: in the first, we can tell CF to treat the struct value as a string, but in the second that's kind of hard to do.

Re: JSON Encoding bug (again...)
Not that it helps, but the same happens in CF10 as well.

JSON Encoding Bug
I just want to say I think that it is seriously lame that Adobe has not fixed the encoding issues with serializeJSON() converting 'yes' / 'no' to true/false. Yes, you can append as string and then convert it back afterwards and all that, but that's just adding extra processing overhead and hoakiness(?), and this bug has been around for so long - its now officially annoying. Sorry, I know, I'm just ranting.
