If I am validating two runtime dialog fields of type FormIntControl using same Validate method , I am getting error as RegisterOverrideMethod was called twice for the same object for method 'validate'. You can only override a method once per instance. Is there any way to bypass this issue as i want to use same validate method for both the fields.

Please help me to get out of this issue

    Hi All,

    I have resolved this issue by adding below method in class. It is mandatory to comment super.

       // PostRun Method

       public void postRun()

       {

           //super();

       }

    Hi Ali,

    I have the same error message as I am using registeroverridemethod more than once (infact thrice).

    Did you find a solution?

    Commenting super() did not work for me.

    dfBOMId = this.bindInfo().getDialogField(contract, methodStr(KittingContract, parmBOMID));
    dfBOMId.registerOverrideMethod(methodStr(FormStringControl, lookup), methodStr(KittingReportUIBuilder, BOMIdLookup), this);
    if (dfBOMId){
    dfBOMId.lookupButton(1);
    }
    //Warehouse
    dfWarehouse = this.bindInfo().getDialogField(contract, methodStr(KittingContract, parmWarehouse));
    dfWarehouse.registerOverrideMethod(methodStr(FormStringControl, lookup), methodStr(KittingReportUIBuilder, WarehouseLookup), this);
    if (dfWarehouse){
    dfWarehouse.lookupButton(2);
    }
    //Kit Levels
    dfKitLevels = this.bindInfo().getDialogField(contract, methodStr(KittingContract, parmKitLevels));
    dfKitLevels.registerOverrideMethod(methodStr(FormStringControl, lookup), methodStr(KittingReportUIBuilder, KitLevelsLookup), this);
    if (dfKitLevels){
    dfKitLevels.lookupButton(3);

    Thanks,

    Hi Oleksandr,

    One suggestion for you is try to  category the code  with respect to method.

    Don't put all code in one method that is not recommended and would not help in debugging.

    Thanks,

    Raziq

    Hi Raziq, I have found to solution in this post dynamicsaxinsight.wordpress.com/.../ax-2012-multi-select-lookup-for-ssrs-report-dialog

    So I have done only one thing: postRun() method overridden to comment out super() method call.

    super() is commented to avoid the following exception:

    RegisterOverrideMethod was called twice for the same object for method ‘lookup’…

    Let me know if you still need my UIBuilder. Oleksandr

    Hi Ragoza Oleksandr,

     

    Could you please share your whole UI Builder class code. The reason why I am asking this is, you called to registeroverridemethod only once in this piece of code.

     

    Please share it for further trouble shooting.

     

    Thanks,

    Raziq

    Hi Mohd, please see below:

    class ReportUIBuilder extends SrsReportDataContractUIBuilder

    {

       DialogField                  dialogFieldCategory,

                                    dialogFieldMonthQuarter,

                                    dialogFieldFromDate,

                                    dialogFieldToDate,

                                    dialogFieldReportDate;

       ReportContract insuranceReportContract;

    }

    public void postRun()

    {

       Dialog dialogLocal                    = this.dialog();

       ReportContract contract = this.dataContractObject();

       super();

       dialogFieldCategory     = this.bindInfo().getDialogField(this.dataContractObject(), methodStr(ReportContract, parmCategoryList));

       dialogFieldMonthQuarter = this.bindInfo().getDialogField(this.dataContractObject(), methodStr(ReportContract, parmMonthQuarter));

       dialogFieldReportDate   = this.bindInfo().getDialogField(this.dataContractObject(), methodStr(ReportContract, parmReportDate));

       dialogFieldFromDate     = this.bindInfo().getDialogField(this.dataContractObject(), methodStr(ReportContract, parmFromDate));

       dialogFieldToDate       = this.bindInfo().getDialogField(this.dataContractObject(), methodStr(ReportContract, parmToDate));

       dialogFieldCategory.registerOverrideMethod(methodstr(FormStringControl, lookup), methodstr(ReportUIBuilder, categoryLookup), this);

       dialogFieldFromDate.allowEdit(false);

       dialogFieldToDate.allowEdit(false);

    }
