XML Sequencing creating new nodes with same name

[subhrajyotimoitra]

Hello,

I am trying to use Modeshape4.0 in embedded form.

Below is a sequencing config i have in my config json.

"sequencing" : {

        "removeDerivedContentWithOriginal" : true,

        "sequencers" : {

            "XSD Sequencer" : {

                "classname" : "xsdsequencer",

                "pathExpressions" : [ "default://(*.xsd)/jcr:content[@jcr:data] => /xsd_metadata" ]

            },

            "XML Sequencer" : {

                "classname" : "xmlsequencer",

                "pathExpressions" : [ "default://(*.(xml|cmmn|bpmn|bpmn2))/jcr:content[@jcr:data] => /xml_metadata" ]

            },

            "Image Sequencer" : {

                "description" : "Images sequencer",

                "classname" : "ImageSequencer",

                "pathExpressions" : [ "default://(*.(gif|png|pict|jpg))/jcr:content[@jcr:data] => /img_metadata" ]

            }

        }

    }

When i upload different xml, cmmn, bpmn files into the repo, different xml_metadata nodes are created, nodeids for these nodes are different.

So now I have paths like /xml_metadata, /xml_metadata[2] and /xml_metadata[3]

for 3 files i upload into the repository.

I want all the files to appear under one /xml_metadata node.

How do i do it? What am i doing wrong? Any pointers where the problem might be?

Please help.

Thanks,

Subhro.

Sequencing is asynchronous by nature and each uploaded file will be sequenced off a separate thread with no synchronization between the different threads. This means in your example, that if there is no xml_metadata node at the beginning and you upload several XML files at the same time each thread will compete & attempt to create the parent xml_metadata node resulting in several same name siblings.

I think the easiest solution in this case is to make sure the output node exists *before* you start uploading documents. You can very easily do this in your code or you can use an initial content file (see Initial Content - ModeShape 4 - Project Documentation Editor)

Perfect.. couldn't get better with the initial content feature....

Thanks for your time.
