Alright, so after seeing this reply and
going slightly insane for awhile I actually narrowed down the problem….and
wow what a WEIRD bug.
Ok, here goes:
<mx:HTTPService showBusyCursor="true"
id="GetSalesData"
url=""
result="event.call.resultHandler(
event )"
fault="event.call.faultHandler(
event )"/>
If I run this, it causes the problem I
talked about – chart doesn’t update, datagrid does, yadda yadda. So
I refresh the flex application like crazy (yes, spam refresh…I was mad at
this stupid thing J) and IT WORKED. So dumbfounded, I hit refresh in a few seconds and
it breaks.
So I decide, it’s gotta be the call right? So I go to that url and run it
and see the result (it’s an xml file) and decide to copy the result xml
into a hard file called dummy.xml.
<mx:HTTPService showBusyCursor="true"
id="GetSalesData"
url=""
result="event.call.resultHandler(
event )"
fault="event.call.faultHandler(
event )"/>
Guess what? It worked 100%. So I’m now thinking….ok, what the heck.
You’re telling me the service isn’t working fine? Because remember,
this works exactly fine in non-Cairngorm….so I take the two files. I run
the service link and do Save Page As – then I took the “view source”
of that, write it into an xml file and save it. Compare the two, exactly the
same file size and everything – zero file difference using a file
comparison tool. So…..I delve deeper and finally figure it out and you’re
not going believe me but I swear it’s true.
If my service takes more than 1second to run, I get all these problems. If it
takes less than 1 second, it runs perfect.
Yup, that’s right – using CFdebugging I found out how long the
service was running and if I can cut-down the file runtime under a second (aka
the hard file or spamming refresh to get a saved result), it runs fine. If it
takes more than 1 second, I get all these problems where the chart doesn’t
show up, the legend is messed up, but the datagrid and the rest is fine…and
if I hard push the data into the chart it works fine.
Seriously the *only* thing I
change between the two is going to that URL above (which produces the exact
same XML but takes a little longer) and a hard-copy of the xml and it works
perfect. Zero coding changes at all besides that one line.
My guess? I know you’re going to think I’m nuts but this has to be
Cairngorm because in the exact same code, if I take the HTTPService out of my
Services.mxml file and move it into the charting template itself – works perfect.
Something is going on in the Delegate, ServiceLocator, or the Chart is
expecting an update to data that isn’t there yet, or….well hell if
I know, all I know is if that webservice for some reason takes longer than 1
second the whole thing breaks. If anyone wants me to pump out any kind of
debugging to see why this is doing this, just let me know - but seriously, all
I change between the two is the url of that service and it goes from working to
not at all.

I’ve posted the code so you can look at what I’m doing – you’ll
notice it’s pretty much to the T exactly like yours. Again, all I need to
do is change that url to my internal url that I put above, have it take more
than 1 second, and it all breaks….

I create an example called "ComplexObjectBinding" that
illustrates
using simple binding and Cairngorm method of a
static ModelLocator.
You can find it here:
http://www.renaun.com/flex2/
Not sure whats up with your code, I pretty much
did you what you
outlined, only thing I can guess is if the
model.hourData is set
before the Template is created you might not fire
a bind event, but
its hard to say with out see the actual source
code.
Either way check out the example above it shows
both methods with a
Custom ChartTemplate and without one.
Its kind of a funny random chart line generate,
have fun making funny
looking lines, hehe...
