请教下，DEP 里 这种多页签的如何控制这个保险公司里有值时，提示分录不能为空。代码如何写？

var bx=pluginCtx.getKDBizPromptBox("prmtlnsuCompany");这个拿到的是空的，调试执行应该可以看出来。

错误信息：Plugin script execute error, please check whether script is right.
方案QJ_Development_modify中的脚本存在问题。脚本如下：
var easImporter = JavaImporter();
easImporter.importPackage(Packages.com.kingdee.bos);
easImporter.importPackage(Packages.com.kingdee.eas.util);
easImporter.importPackage(Packages.com.kingdee.eas.util.client);
with(easImporter){
var txtCause = pluginCtx.getKDTextArea("txtHangtagRemark");
var kdts=pluginCtx.getKDTable("kdtlnsuran");
var bx=pluginCtx.getKDBizPromptBox("prmtlnsuCompany");
//控制分录字段为必录项
if(txtCause.getText().equals(""))
{
MsgBox.showInfo("<上牌备注不能为空>");
SysUtil.abort();
}
if(bx.getValue()!=null && kdts.getRowCount()==0)
{
MsgBox.showInfo("<保险分录不能为空>");
SysUtil.abort();
}
}

Caused exception message is: TypeError: Cannot call method "getValue" of null (unnamed script#15)
