iterator and datatable to auto-reflect payload data structure

[focusfriend]

Is it possible for an iterator and datatable to dynamically reflect
the payload data structure? E.g. show all the values without knowing
upfront the field names and number of fields that are coming in.

So you want it to literally just dump the data into a div as plain
text without formatting? I'm not sure I understand.

I'd suggest doing this data transformation outside the (visible) interface.

<app:script>

$MQL("r:message_to_transform", function(msgtype, data) {

  $MQ("r:transformed_message", $H(data.someproperty).map(Prototype.K));

});
</app:script>

the .map(Prototype.K) is just a way of saying "iterate over this hash, get key-value pairs, and save those in a lsit without changing them"

and then use the transformed message like this:

<app:iterator on="r:transformed_message then execute">

 #{key}: #{value}

</app:iterator>

--Mark

I want to display a grid, but the number of columns can vary within
the different payloads.

I've used a simple PHP bit of code to load the $MQ payload - it's not
fancy, but it works.

<app:script style="display:none;">
$MQ('l:load.datatable',{'rows':[
<? $classObject->spit_out_$mq_rows(); ?>
]});
</app:script>

One way to do it would be to normalize the length of the rows to the
longest length. You could then next iterators to handle the 2d array.

Actually, you should just be able to nest two iterators without the
normalization bit.
