I assigned to Phil, because I believe he wrote most of these `in`
tests, on my advice (bleah).

We should look for other cases where the code is using "in" to detect
what has become a declared
instance variable of a class.

So 'datasets' is a declared instance var of the LzCanvas class, so
that is probably why 'in' is not
the way to test for it. I should probably just initialize it to an
empty hash table, {}, and remove that
null check.

OK, if I change this code in LzDataset.setName, then it works
- if (!('datasets' in canvas) || null == canvas.datasets ) {
+ if (!(canvas['datasets']) || null == canvas.datasets ) {
canvas.datasets = {};
}
so "in" is not behaving the same in swf8 and swf9

I created a bug for this
http://www.openlaszlo.org/jira/browse/LPP-6668
What is really weird is that I put some tracing in, and the bug is
happening on the failing datapointer
because when it sets is xpath to "ds1:/persons", the name
canvas.datasets['ds1'] is unbound,
(but canvas['ds1'] is bound!). How can that be? Why is the other
dataset, ds2, behaving properly?
Who is responsible for setting canvas.datasets[DSETNAME] ? Why
would
it be getting set
in one case but not the other?

I've isolated the issue with multiple tests failing down to this
test
case. There are two
datasets and a datapointer for each one. In the "good" case, the
order
in the app is
dataset, datapointer, dataset, datapointer.
Both datapointers' ondata events fire.
GOOD:
<canvas width="100%" height="600" debug="true">
<dataset name="ds1"
src="http:namespace.xml" request="true" type="http"
ondata="Debug.write('[1] dataset ds1 got ondata')"/>
<datapointer xpath="ds1:/persons" name="pointer_ds1"
ondata="Debug.write('pointer_ds1 ondata received')"/>
<dataset name="ds2"
src="http:namespace.xml" request="true" type="http"
ondata="Debug.write('[2] dataset ds2 got ondata')"/>
<datapointer xpath="ds2:/persons" name="pointer_ds2"
ondata="Debug.write('pointer_ds2 ondata received')"/>
</canvas>
However, if the two datasets come first, and then the two
datapointes,
the first datapointer never seems
to run its ondata handler. So what would the order of these
objects
have to do with it? argh. The debug trace
shows that both datasets fire their ondata events. So is there
some
sort of race condition where the
datapointer misses it's event? How do I tell? I guess putting a
trace
onto the event sender code, to see
if the datapointer is actually registered for the event or not
when it is sent.
This bug does not occur in swf8 or dhtml
BAD:
<canvas width="100%" height="600" debug="true">
<dataset name="ds1"
src="http:namespace.xml" request="true" type="http"
ondata="Debug.write('[1] dataset ds1 got ondata')"/>
<dataset name="ds2"
src="http:namespace.xml" request="true" type="http"
ondata="Debug.write('[2] dataset ds2 got ondata')"/>
<datapointer xpath="ds1:/persons" name="pointer_ds1"
ondata="Debug.write('pointer_ds1 ondata received')"/>
<datapointer xpath="ds2:/persons" name="pointer_ds2"
ondata="Debug.write('pointer_ds2 ondata received')"/>
</canvas>
