    Hi Isomorphic,

    those now sat quite a while. Do you have an opinion on those?
    Especially the "queueStatus is present multiple times" is a bug IMHO. As I gave a customer access to the API now, I expect the question why this is to come up very soon now.

    Thank you & Best regards

    Hi Isomorphic,

    issue #3, same request:
    Code:
    package com.smartgwt.sample.server.listener;
    
    import java.io.Reader;
    import java.io.StringReader;

            Reader jsonReader = new StringReader(convertToCSV(requestValues));
    
            DataImport dataImporter = new DataImport(ImportFormat.CSV, ";");
            dataImporter.setPopulateDisplayFields(true);

    </ReportsToName>
     </record>
    </data>
     </response>
    Issues:
    • As you can see, the queueStatus is now present three times.
    • Generally speaking this is working, but IMHO the workaround with CSV should not be necessary. DataImport-methods should have an overload that take Map<String, Object> and do the conversion displayName->ID.
    • When using JSON or XML, what is the expected structure? Could you add it to the docs? You can see my convertToXML() and convertToJSON(), but the DataImport-docs don't say anything about the enclosing tag or similar.
      Additionally, XML is mentioned as possibility besides XML/CSV in the class description, but never in the methods.
    DataImport contains methods that can be used to import data from a test data file to the List of Maps format commonly used for DataSource records (importToRows()), or directly into a DataSource (importToDataSource()).
    By default the input file is expected to contain comma-delimited data like a .csv file, but JSON and XML are also supported.
    Imported data may be transformed during import, for details search SmartClient Reference for "dataSourceField.importStrategy".
    • As enhancement: It would be great if it were possible to directly add data to a DataSource via a ARC request using the String-to-ID lookup and not to have to call DataImport oneself in a boilerplate method. If this is not a good idea as default for all ADDs for fields with importStrategy="display", then perhaps as additional attribute for an ADD or UPDATE operation binding.

    Hi Isomorphic,

    issue #2 (minor), same setup, but

    Code:
    public DSResponse upload(DSRequest dsRequest, HttpServletRequest servletRequest) throws Exception {
            return new DSResponse(dsRequest.getDataSource()).setSuccess();
    }
    For the request from #1, the result is:
    Code:
    <response>
    <status>
    0
    </status>
    <queueStatus>
    0
    </queueStatus>
    <startRow>
    -1
    </startRow>
    <endRow>
    -1
    </endRow>
    <totalRows>
    -1
    </totalRows>
    <queueStatus>
    0
    </queueStatus>
    <data />
     </response>
    Please note that <queueStatus> is in there twice.

    Best regards

  • 6.1p DataImport importToDataSource issue in combination with RESTHandler

    Hi Isomorphic,

    I'm currently creating an API to my application and hit some bumps here in DataImport I use in combination with RESTHandler (latest 6.1p, v11.1p_2017-11-08).
    The issues/questions are mainly DataImport-related and the whole testcase is serverside only (FF26 Dev mode in Eclipse).

    employeesUpload.ds.xml:
    Code:
    <DataSource xmlns="lmscompany/ds" xmlns:fmt="lmscompany/fmt" ID="employeesUpload" serverType="sql" tableName="employeeTable" recordName="employee" useAnsiJoins="true">

    As you can see, importToDataSource() does not use setPopulateDisplayFields(true), even though it is set. This does work for importDataSourceRecords().
