Do you have version after commit 3870b32131caf35fdc9e54a6446f546e6eb0e01d ? It should be fixed by it.

[tomas-knap]

Ok, will check on that

[tomas-knap]

Still appears, please check ODCS

[tomas-knap]

This problem still appears, see ODCS, exec 934, browse/query for XSLT/rdfInput.

Please look on that

[bogo777]

I wasn't able to reproduce it on exec 934, but it occured for some RUIAN execution for me. It seems that this call: executionInfo.dpu(dpuInstance) returns null and is cause of the trouble. I added check, that it is so, so after loading newest version to odcs we could confirm it from log. But I will need help from @skodape , as I don't know why this code would return null for finished execution...

[tomas-knap]

@skoda, please look on that when you find some time

[tomas-knap]

Cannot reproduce
