When I add --dynamic-load=DEMO_.* to the __main__.py script file like so:
TARGETS = {
'Showcase.py': dict(path='src', options=['--dynamic-load=DEMO_.*']),
}
the application compiles, and loads all the pyjamas.*.js files but then
tries to download files such as
pyjamas.ui.pyjamas.js, pyjamas.sys.js, and pyjamas.ui.sys.js, but receive a
404 error (which they should)..
I'm compiling the DEMO_* files on my own in the compile.py script, but
these fail to import properly with the __import__ statement..
Any advice?
Thanks!
