#8 filter*param doesn't work correctly
A filternode can't access a parameter that was added and exported by a filternetwork, for example
(filternetwork sample
(node wf write_file
(export-param filename filename "name of savefile")
)
(node ain audio_in)
(connect ain left_out wf left_in)
(connect ain right_out wf right_in)
)
This is IMHO a valid network file. Test log:
ehlert@frodo:~/Proggen/glame/src/filter> ./test_network net_test_sample filename foo.wav
parse_node: added node write_file (filter wf)
parse_node: export-param: filternetwork_add_param(net,wf,filename,filename,"name of savefile")
parse_node: finished node
parse_node: added node audio_in (filter ain)
parse_node: finished node
parse_connect: added connection ain left_out wf left_in
parse_connect: added connection ain right_out wf right_in
setting parameter filename to foo.wav

That's it.
If you want to set a parameter of type string you have to provide a quoted string, i.e.
\"capt.wav\" instead of simply capt.wav. I do not consider this a real bug, but a documentation one - but I may want to add the feature to detect a missing quotation.
