Axapta 尝试从FormRun检索数据源时获取null
我有两张表格,我们称之为表格A和表格B。 在表格A中,我有一个按钮(空白按钮),当点击该按钮时,它将重定向到带有参数的表格B,该参数将被注入表格B的数据源。我检索表格B的数据源失败,它总是返回nullAxapta 尝试从FormRun检索数据源时获取null,axapta,x++,Axapta,X++,我有两张表格,我们称之为表格A和表格B。 在表格A中,我有一个按钮(空白按钮),当点击该按钮时,它将重定向到带有参数的表格B,该参数将被注入表格B的数据源。我检索表格B的数据源失败,它总是返回null [FormControlEventHandler(formControlStr(htVehicleListPage, FormCommandButtonControl1), FormControlEventType::Clicked)] public static void FormCom

FormRun
只是……它是正在运行的表单对象。您的openningFormDataSource
将为null,因为您在formRunObj.init()之前调用它代码>并且表单尚未运行
它先是Form.init()
,然后是Form…Datasource.init()
,然后基本上是Form.run()
将formRunObj.init()
移到更高的位置,然后重试
