报表以弹窗形式展示，刷新报错

adjust

如题，根据主页面的数据，弹窗展示对应的报表，现在有个问题是，每次弹窗打开报表，提示 Cannot read property 'refresh' of null，错误点是在wReceiverReceive方法下的
  // 刷新报表
    this.comp("report1").refresh();
refresh方法错误，详细错误信息如下
TypeError: Cannot read property 'refresh' of null at n.Model.wReceiverReceive (http://localhost:8080/x5/UI2/v_bcbb05dcd91e41808dba444501761585l_zh_CNs_desktopd_pc/ScientificResearch/ProjectBudget/process/ProjectBudget/FundBudgetActivityReport.js:79:23) at n.fire (http://localhost:8080/x5/UI2/v_02bb57e7098e4c76b73c4ce24c70898fl_zh_CNs_desktopd_pc/system/core.min.js:71:237894) at n.fireEvent (http://localhost:8080/x5/UI2/v_02bb57e7098e4c76b73c4ce24c70898fl_zh_CNs_desktopd_pc/system/core.min.js:71:239058) at n.callParent (http://localhost:8080/x5/UI2/v_02bb57e7098e4c76b73c4ce24c70898fl_zh_CNs_desktopd_pc/system/core.min.js:71:235333) at n.fireEvent (http://localhost:8080/x5/UI2/v_f35fae712fb54e828b6f66f8f4d7de3al_zh_CNs_desktopd_pc/system/common.min.js:15:3768) at n.doReceive (http://localhost:8080/x5/UI2/v_84e7dec973b94fd3a48b68d87a4f92a8l_zh_CNs_desktopd_pc/system/components/comp.min.js:144:269042) at n._doReceive (http://localhost:8080/x5/UI2/v_84e7dec973b94fd3a48b68d87a4f92a8l_zh_CNs_desktopd_pc/system/components/comp.min.js:144:268804) at n.fire (http://localhost:8080/x5/UI2/v_02bb57e7098e4c76b73c4ce24c70898fl_zh_CNs_desktopd_pc/system/core.min.js:71:237894) at n.fireEvent (http://localhost:8080/x5/UI2/v_02bb57e7098e4c76b73c4ce24c70898fl_zh_CNs_desktopd_pc/system/core.min.js:71:239058) at n.attached (http://localhost:8080/x5/UI2/v_02bb57e7098e4c76b73c4ce24c70898fl_zh_CNs_desktopd_pc/system/core.min.js:71:267809)

如果屏蔽refresh方法，则弹窗报表的数据只显示第一次加载后的数据；如果忽略错误，则显示的报表数据正确。

debugger调试看看this.comp("report1")获取的正确吗？
