---------------------------------
Summary: ode:delete fails when removing multiple elements
Key: ODE-991
URL: https://issues.apache.org/jira/browse/ODE-991
Project: ODE
Issue Type: Bug
Components: BPEL Runtime
Affects Versions: 1.3.2
Environment: Currently running r832808 with a couple of local patches.
Reporter: Ciaran Jessup
Priority: Minor
If ode:delete($Foo/x:child) returns multiple elements for deletion my workflow
fails with a selectionFailure :(
It seems to be caused by the Delete method being passed a SequenceExtent rather
than the expected List etc.
Whilst adding in support for that type (not sure why this only affects me ?) I
also found that the logic for removing child elements from the cloned element
that the function returns was squiffy. It seemed as if it was mutating the
collection so the position offsets were incorrect and the wrong elements would
get removed from the parent element. I've updated the code to resolve that too
(there is a better solution as alluded to in my code comments in the patch)
Ironically? I've stopped using ode:delete even with my 'fixes' and moved to use
an XSL transform as this turned out to be more memory efficient when doing
multiple deletes so I'm just providing my fixes back in case anyone else needs
/ wants them.
