Error in TeeProcessor

Hi,

We are currently trying to update from orbeon 3.6 to orbeon 3.8 and I keep on seeing the following error in my logs

Tee state was cleared and re-read for output: instance

I did not have this problem with the previous orbeon version.

What we are doing is the following:
We have some custom processor we wrote in java, in this processor we take the input, unmarshal the xml to objects, tranform those and the marshal them back to xml to return to orbeon.

The code looks like this:

        public void generateData(PipelineContext context, ContentHandler contentHandler) throws Exception {
                DocumentResult docResult = new DocumentResult();
                Document instance = readInputAsDOM4J(context, "instance");
                ...
                //here the proposalModelResult object is generated, then marshalled to xml using jaxb
                MarshallerFactory.getProposalMarshaller().marshal(proposalModelResult, docResult);
                Document xmlDocument = docResult.getDocument();
                LocationSAXWriter saxWriter = new LocationSAXWriter();
                saxWriter.setContentHandler(contentHandler);
                saxWriter.write(xmlDocument);
        }

Can you please tell me what I am doing wrong?

Thanks,

Antoine

Antoine,

This probably means you have a processor which reads its input
multiple times during the same pipeline execution.

This is not allowed by the pipeline engine and the internal Tee
processor enforces that rule.

Since you have a custom processor this is a red flag. Can you see any
way this can happen in your system?

Thanks Eric,

Indeed I don't have this with all my processors.
I'll search in that direction.

Thanks,

Antoine
