I need to use a condition on automation chain for verify the uid on documents in the repository but I don´t know how to do that? I have reviewed all operations in studio but I don't see something with conditions</P> Mon, 06 Feb 2012 19:34:32 GMT https://connect.hyland.com/t5/nuxeo-forum/how-to-validate-the-document-creation-with-unique-uid-using/m-p/324282#M11283 geekonspace 2012-02-06T19:34:32Z https://connect.hyland.com/t5/nuxeo-forum/how-to-validate-the-document-creation-with-unique-uid-using/m-p/324283#M11284 <P>Hi,</P> <P>Since studio is using MVEL, i guess you can use the usual MVEL synthx for conditions: <A href="http://docs.codehaus.org/display/MVEL/MVEL+2.0+Control+Flow" target="test_blank">http://docs.codehaus.org/display/MVEL/MVEL+2.0+Control+Flow</A></P> Wed, 08 Feb 2012 17:32:34 GMT https://connect.hyland.com/t5/nuxeo-forum/how-to-validate-the-document-creation-with-unique-uid-using/m-p/324283#M11284 Laurent_Doguin 2012-02-08T17:32:34Z https://connect.hyland.com/t5/nuxeo-forum/how-to-validate-the-document-creation-with-unique-uid-using/m-p/324284#M11285 <P>Another way of doing it is to create the id automatically using Fn.getNextId (maybe using the metadata of the document) so that you will be sure to have a unique id.

This uid always is get from another value of metadata that user write</P> Thu, 09 Feb 2012 14:03:15 GMT https://connect.hyland.com/t5/nuxeo-forum/how-to-validate-the-document-creation-with-unique-uid-using/m-p/324285#M11286 geekonspace 2012-02-09T14:03:15Z https://connect.hyland.com/t5/nuxeo-forum/how-to-validate-the-document-creation-with-unique-uid-using/m-p/324286#M11287 <P>Doing the "count" fo your select is something that can be done easily with automation (using This.size() for exemple) but the problem is more that we don't currently any operation that would break the transaction nicely. The best option would be to write a JSF validator that does what you meant and reference it in the "validator" property of your widget. This is development with Nuxeo IDE.</P> Fri, 10 Feb 2012 07:48:48 GMT https://connect.hyland.com/t5/nuxeo-forum/how-to-validate-the-document-creation-with-unique-uid-using/m-p/324286#M11287 Alain_ESCAFFRE 2012-02-10T07:48:48Z
