I have experienced the exact same
problem. In my case I was loading a resource that wasn’t on the server
or was null. It would then freeze all data traffic like you are talking about.
Very strange problem and I look forward to hearing more about the cause.

where setSource on a replicating view causesall data communication to freeze
I will take a look. One
question, the timeout for a load request is 30 seconds by default, does
anything seem to unfreeze if you wait 30 seconds?
There are only two loader network connections available to the app (thanks,
Microsoft) and if something is holding them locked then no other load requests
will be permitted to start.

I'm about to submit a bug
on this and I can't find any open relevant
ones in JIRA, but was wondering if anyone else had come across it.
-----------------
Summary:
I have views that replicate according to their bound data- they have a
subview with a datapath bound to an image source attribute and call
setSource() from the applyData method. I change that bound data
based
on user action- in my test case, a button click. If that data
changes
too quickly(If you double/triple click), setSource() is called, but it
doesn't actually go and request the image. Not only that, but from
that
point forward, *ALL* outbound requests fail silently.
-----------------
Test files:
test-loadingbug.lzx - embededed data and laszlo gui
images/ - directory of images to load
-----------------
To reproduce: (after unzipping to a working laszlo directory)
1. Run test-loadingbug.lzx
2. Single click "apply a new dataset" to see views
replicate and load
images
3. Single click "apply a new dataset" to see views
replicate again with
different data
4. Click "try sending data" to see a request send (and
fail: expected
behavior) in the debugger our output field
5. Click "apply a new dataset" several times quickly,
until the
replicated views show as gray boxes with no images
6. Click "try sending data" to see a request send, but not
show
response (fail) from server.
----------------
You can verify with an external debugger like liveHttpHeaders, Charles,
or Fiddler that the calls are or are not being sent.
---------------
Notes:
* Reproduces with both proxied and unproxied applications
* Reproduces with FP7 in IE, FP8 in Firefox, and the standalone SWF
player with compiled lzx.swf
* Reproduces with setSource() called from ondata event instead of
applyData method
* Reproduces with OpenLaszlo 3.2 and 3.3
* Reproduces with images located in local filesystem or loaded remotely
------------------
My guess is that there's something going on when a replicated view is
removed while an image is still loading into it. I'm not sure where
to
look from here.
Any thoughts or ideas?
Thanks much,
Kathryn
