[Taverna-users] Oversized output

Fri, 25 Sep 2009 00:45:21 -0700 

Dear Taverna Team,
I was trying out a new web service and I have been too generous on my input parameters. The result was a large (6MB) xml text output which Taverna displayed dutifully. But as soon as I try any interaction with that output Taverna sort of freezes and does not recover. 


Would it not be better not to display the output if it is too large for 
interaction, but still give the user the option to save the file. That 
at least would allow the user to continue to work (e.g. save the 
workflow). Just a suggestion.



I attach the offending workflow, in case someone wants to see the 
phenomenon themselves.


Best Regards,
Anja Le Blanc
