[Proto-Scripty] Re: subtleties of control flow
Hi,
It would be useful if you said what the `json` variable references.
You're treating whatever it is like an array, so I'll assume that here
-- or at least, that it has a `length` property and properties with
the names `0`, `1`, etc.
So you're saying
1. It does show testing header==true at least once.
2. It does not show testing continuing flow.
3. It does not show testing header==false.
I can't immediately think of any form that `json` would take that
would exhibit the behavior you're describing, particularly not #1
combined with #2. Have you edited that code snippet by any chance? For
instance, replaced some other output mechanism with `alert`? If so,
I'd have a good hard look at the output mechanism you replaced.
FWIW.

Re: [Proto-Scripty] Re: subtleties of control flow
Hi TJ
Sorry for insufficient detail
The json object is returned from the server and is a JSONArray, composed of
hetrogenous elements, but all of which have a server-side defined boolean
header element. What I was hoping to do is put both types of elements into
this one JSONArray and selectively process. I have it working just fine
with all header elements, but I just cant get it to execute the
header==false code. What I found so odd was the the non-testing line didnt
even print. I would have expected that line to print along with either
depending on the value of header. I know how preposterous it is to claim
control flow is broken, but it is appearing like it is just breaking out of
the loop and not executing anything. I will try changing the serial
position, but it should print that testing continuing flow line no matter
what. I am nonplused.

[Proto-Scripty] Re: subtleties of control flow
Hi,
The json object is returned from the server and is a JSONArray...
You mean JSONArray as in the Java wrapper for JSON arrays from
json.org? An array can't be the top-level object in a JSON dataset.
Not that that's likely to be your problem, I'm just saying...
Do you ever see more than one header==true alerts? Are they really
alerts? (See my earlier note.)

Re: [Proto-Scripty] Re: subtleties of control flow
Hi TJ
Yes, I am using json.org jars to serialize out a JSONArray that I created
and populated with my hetrogenous object types server-side. No I only saw
either header==true alert and I did make sure there was nothing hiding. I
am going to keep pruning back code until I get something I can agree is
correct.
