Hello,
Using Taverna 2.3 i've created a workflow consisting of a single beanshell
processor. This processor has two input ports (single value - depth 0) and
one output port. Then created two workflow input ports again with depth 0
(single value). I've tested it and it has worked.
Later i've created a new workflow and added the previous workflow as a
nested workflow. To iterate many times over the previous workflow, i have
added two workflow input ports with depth 1. As list handling method i set
dot product.
I run the new workflow with two list of values. If in any of the iteration
an error happens, i see it in the workflow results, in the output port's
list. After restarting the taverna, however, the output port's result were
not there anymore. A warning during execution has been issued, which is
probably the cause:
WARN 2012-04-24 10:08:26,098
(net.sf.taverna.t2.provenance.lineageservice.WorkflowDataProcessor:215) -
No workflow port data for /o:abc_Beanshell_out1
A possible fix:
I studied the WorkflowDataProcessor class a little and found that a for
loop at line 114 is enclosed in a try catch:
try{ // line 112
for(...){ // line 114
......
}
}catch(SQLException e){....}
If an exception happens in the loop, it will be catched in the catch clause
but also it means that the for loop won't complete. So i changed it to:
for(...){
try{
......
}catch(SQLException e){...}
}
This has solved my problem but someone needs to check for the side effects.
Best wishes,
Ilhami Visne
P.S.: For testing one can create a beanshell with two input ports for two
number values and in the beanshell these two number can be divided. To
cause an error one of the number can be zero.
