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
