Hi
I've got a large number of XML files I'm trying to extract the <reaction> elements out of. This works fine when the node is run normally.
The XPath node appears to be listed as streamble. However, when I place this node alone inside a wrapped meta node and select streaming executor I get the following error:
ERROR getReactions() 0:31 Caught "NullPointerException": null
ERROR getReactions() 0:31 Caught "IllegalStateException": Illegal state "CONFIGURED_QUEUED" encountered in method "org.knime.core.node.workflow.SubNodeContainer#performStateTransitionEXECUTING" in node getReactions() 0:31
ERROR getReactions() 0:31 Caught "IllegalStateException": Illegal state "CONFIGURED_QUEUED" encountered in method "org.knime.core.node.workflow.SubNodeContainer#performStateTransitionPOSTEXECUTE" in node getReactions() 0:31
ERROR getReactions() 0:31 Caught "IllegalStateException": Illegal state "CONFIGURED_QUEUED" encountered in method "org.knime.core.node.workflow.SubNodeContainer#performStateTransitionEXECUTED" in node getReactions() 0:31
Then the meta node is tuck in an executing state.
KNIME log output:
