errors on submit

[Martin Rosellen]

Dear XNAT community,

we, Max Plack institute Berlin, want to set up XNAT for our research data and try to figure out how to define our own XSD Schemas. We understood, that custom XSD schemata should extend the schema xnat:subjectAssessorData. As a starting point we defined the following XSD:

<?xml version="1.0" encoding="UTF-8"?>

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xnat="http://nrg.wustl.edu/xnat" xmlns:xyz="http://nrg.wustl.edu/xnat_myData" targetNamespace="http://nrg.wustl.edu/xnat_myData"  elementFormDefault="qualified" attributeFormDefault="unqualified">

 <xs:import namespace="http://nrg.wustl.edu/xnat" schemaLocation="../xnat/xnat.xsd"/>

   <xs:element name="MyAssessment" type="xyz:myAssessorData"/>

   

        <xs:complexType name="myAssessorData">

         <xs:complexContent>

                    <xs:extension base="xnat:subjectAssessorData">

                 </xs:extension>

        </xs:complexContent>

   </xs:complexType>

</xs:schema>

We added this line to the InstanceSettings.xml:

<Data_Model File_Name="myData.xsd" File_Location="%XDAT_PROJECT%/schemas/myData" DB="%DB_NAME%"/>

As admin we set it up as additional data type using the web interface. After logging out and in again we can choose the MyAssessment from experiments selection.

 

The problem is, that we get the following error on submit:

ERROR: function i_xyz_myassessordata(unknown, integer, boolean, boolean, boolean) does not exist Hint: No function matches the given name and argument types. You might need to add explicit type casts. Position: 8

Note, that we did not fill out any other fields than “Experiment ID in this project“. We get more detailed information on this error in the log files, xdat.log and sql.log. xdat.log points to Position: 5619 of the sql statement. We highlighted what we think is the position 5619 in the logged sql statement found in sql.log.

Xdat.log:

2016-06-14 12:13:51,893 - SELECT i_xyz_myAssessorData('XNAT_TEST_IMPORT_E00003',0,FALSE,TRUE,false)

We found out, that after putting in something in the note field of “xyz:myAssessorData/resources/resource[0]” the error message changes to “org.nrg.xft.XFTItem cannot be cast to org.nrg.xdat.model.XnatAbstractresourceI” (see screenshots) whereas the same errors as the ones above get logged.

Has someone encountered the same issue?

[Herrick, Rick]

Did you run the schema update SQL after running the update.sh script? Something like:

 

cd deployments/xnat

psql -f sql/xnat-update.sql

 

It looks like you have the XML schema imported properly, but not the data schema to support storing the data.

Hi Rick,

thanks for the quick help. The update did run but we still get the same error.

[Martin Rosellen]

Having a deeper dive into the sql, we found out that the create table statement for xyz_myAssessorData is in the ...database....sql and is not part of the ...database...-update.sql. Also no other statements containing xyz_myAssessorData are found in the -update.sql, both in deployments and under projects. It seems like the create table statement for xyz_myAssessorData in the ...database....sql never gets executed.

[Herrick, Rick]

Try running the update.sh script again. If the tables for your data type aren't there but the data type schema is referenced in your instance settings, the script should be generated with the appropriate SQL to create them. I'm not sure how you got into the state you're in, but an update should resolve it.

Sent from Outlook on my iPhone: please excuse typos or terse responses.

[Martin Rosellen]

thanks again Rick. We managed to set up the data base tables for our new data type. Unfortunately we still get the 'org.nrg.xft.XFTItem cannot be cast to org.nrg.xdat.model.XnatAbstractresourceI'. We are trying to understand why and where, also because we are interested in how the objects that are handed to the logic that save to the data base have to look like.

[Herrick, Rick]

It’s really hard to say why that might be happening without having the assessor definition and specifics on the data you’re trying to save when you get the error. Also, when you get the error in the UI, are there any entries in the logs on the server side that occur at the same time? That might help us understand what’s happening a bit better.

I am still using the example I described in the initial post:

<?xml version="1.0" encoding="UTF-8"?>

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xnat="http://nrg.wustl.edu/xnat" xmlns:xyz="http://nrg.wustl.edu/xnat_myData" targetNamespace="http://nrg.wustl.edu/xnat_myData"  elementFormDefault="qualified" attributeFormDefault="unqualified">


 <xs:import namespace="http://nrg.wustl.edu/xnat" schemaLocation="../xnat/xnat.xsd"/>

    <xs:element name="MyAssessment" type="xyz:myAssessorData"/>

     

        <xs:complexType name="myAssessorData">

          <xs:complexContent>

                     <xs:extension base="xnat:subjectAssessorData">

                  </xs:extension>

         </xs:complexContent>

    </xs:complexType>

</xs:schema>

Ever since the tables were set up correctly no errors get logged anymore in sql.log or xdat.log or any other log file on the server.
