[Taverna-users] Do I have to connect input data to every input port ?

[Sureerat K. <ma...@gm...>]

Hi everyone,

I've used gSoap to create web service server and gSoap supports using
default values for omitted data.

The problem is do I have to connect input data to every workflow input ports
?
I've seen this (
http://www.taverna.org.uk/documentation/faq/building-workflows/connecting-all-ports/
)
but I'm not *sure* that's *relevant to my problem*. They said "you will not
always have to set them all".
So, if I don't want to pass some optional inputs, how to deal with it ?
I've tried to leave the data in input port blank, but Taverna didn't allow
me to do that.
I've also tried not to connect the input port to the workflow but it didn't
work.
Taverna keeped running workflow and didn't return any output.

Thanks for any help,
Nan
(btw, sorry for my poor english)
