shit, do they have wifi in the deepest darkest France such as Cafe paris in
Sct Tropez.

Next time I goes on hollyday I must go to the darkest place in the jungle
of Borneo just to get rid of wifi ;-)

Actually ignore that - it worked when I connected to a wifi, as opposed to
a slow cellular connection.

The example doesn't work for me on an iPad even using a high speed

Kevin/Nathan

Kevin’s error is probably a classic AJAX error when launching multiple

AJAX

requests where the results depends on each other.

Gent, AJAX runs async by default and javascript processing continues

while

the AJAX requests are performed. That is why we have to put the

javascript

that process the result into the AJAX object.

The statement >>> this.req.open(this.method, this.url, true); in

function

ht_HttpReqObj <<< parm 3 (async) in .open should be changed to false

that

means sync. It will slow things down but other javascript processing

will

wait until the AJAX request is done and if it fails, it will lock the
client until a HTTP error is received (long wait).

Synchronous AJAX is a no go/bad design used in large scale because of
client lock ups so Nathan will need a general event handler that

monitors

the status of the fired AJAX requests and then trigger the HTML

rendering

when the AJAX requests that depends on each other has signal they are

done.

Yes basically you are right - the individual function (or context) is a
markup that to all intents and purposes is xml (validated by an xsd)
containing references to JavaScript components and/or HTML elements.

The

JavaScript components have options (attributes) that may be bound to
attributes of the data model.

The way we do it, there is no HTML exchanged between the client and

server

... Just the data model (JSON) is exchanged, and the UI reacts to the
content via observers - basically events that get triggered when a

data

element in the model changes.

It sounds like you may be using a <tag> language other than HTML, or

a UI

defined by JSON or JavaScript instead of HTML. I suppose either

approach,

including HTML has its pros and cons.
