D365新表单未填充值

Question

需要显示一个区域的所有部分。我创建了新表单PMCContractAreasDialog。当我在合同表中单击特定合同行时，应打开新表单并显示一个区域的所有部分。总之，合同线上应该有相同的内容。但是每次我单击按钮时，表单都是空的。我想念什么吗？

[Form]
public class PMCContractAreasDialog extends FormRun
{

    [FormObservable]
    date                                currWorkingDate;

    [FormObservable]
    boolean                             commonAreasRead;

    PMERentalObjectAreaValueCl          tmpRentalAreaCl;
    PMETmpRentalObjectArea              tmpArea;


    public void init ()
    {
        super();

        pmcContractLine_ds.linkActive();

    }

    public void activate(boolean _active)
    {
        PMCContractArea contractArea;
        AmountMST sumContractArea;


        pmcContractLine_ds.readCommonAreas(pmcContractLine);
        h1_h2.realValue(pmcContractLine_ds.h1_h2(pmcContractLine));
        efa.realValue(pmcContractLine_ds.efa(pmcContractLine));
        bfa.realValue(pmcContractLine_ds.bfa(pmcContractLine));
        mfa.realValue(pmcContractLine_ds.mfa(pmcContractLine));
        sumArea.realValue(h1_h2.realValue() + efa.realValue() + bfa.realValue() + mfa.realValue());

    }
