Posted on by ron_ron 180

Hi All,

How to fetch data in controller and contract class to create a report? I'm already done in generating xml file, but the metadata doesn't any information from the table that I've used.

Thanks for the response.

    Hi,

    Could you provide some more information about A2X classes as I am not much aware of it or might be known with a different name.

    Hi,

    Are you getting this error in data provider class. You can check the method processReport of class CustAccountStatementIntDP and implement your code.

    Code: CustAccountStatementIntContract contract = this.parmDataContract();

             fromDate                = contract.parmFromDate();

             toDate                  = contract.parmToDate() ? contract.parmToDate() : dateMax();

    Hi,

    When I initialize the value of my contract class

    like this rdpContract as ContractClassName , and when I print my report,  the error pops and its says that the object is not initialized. How to fix it?

    Thank you.

    Hi,

    If you have business logic, then we need to use DP class and report can be developed only based on query too.Can you provide us your code, will try to figure out the issue.

    Hi,

    I used query instead of Report Data provider.

    Is it okay to use DP class?

    I can't call contract = rdpContract as ContractClassName;

    Thanks.

    Hi All,

    Is it okay to use DP class?  Because I used query for creating report.

    Thanks.

    Hi,

    You can check SalesInvoiceDP.getDataFromContract() to see how to get contract parameters in report DP class.

    Kind Regards,

    István

    RE: Contract and controller class

    Hi,

    Values from contract class are usually retrieved in DP class. Please check the following parameters in your DP class. 

    Class: DP suffix class

    Method: ClassDeclaration

    Parameters: [

       SRSReportQueryAttribute(queryStr(ReportQueryName)),

       SRSReportParameterAttribute(classStr(ContractClassName))

    ]

    Class: DP suffix class

    Method: processReport

    Code: contractclassvaraible= this.parmDataContract() as ContractClassName;

    Retrieving the value:  variable= contractClassVariable.parmmethod();

    You can take reference of following classes to check implementation details: CustAccountStatementIntContract, CustAccountStatementIntController and CustAccountStatementIntDP.
