JavaScript Web资源问题:getGrid()突然开始失败

Question

我有一些不同的JavaScript web资源使用getGrid((，在我在D365中启用2020 Wave 1更新后，所有这些资源本周都开始失败。错误消息显示：

"发生错误：类型错误：无法获取未定义或null引用的属性'getGrid'">

这是我的代码：

function GetTotalResourceCount(executionContext) {
console.log("function started");
var execContext = executionContext;
var formContext = executionContext.getFormContext();
var resourceyescount = 0;
try {
var gridCtx = formContext._gridControl;
var grid = gridCtx.getGrid();
var allRows = grid.getRows();
var duplicatesFound = 0;
//loop through rows and get the attribute collection
allRows.forEach(function (row, rowIndex) {
var thisRow = row.getData().entity;
var thisRowId = thisRow.getId();
var thisResource = "";
var thisResourceName = "";
var thisResourceID = "";
console.log("this row id=" + thisRowId);
var thisAttributeColl = row.getData().entity.attributes;
thisAttributeColl.forEach(function (thisAttribute, attrIndex) {
var msg = "";
if (thisAttribute.getName() == "new_resource") {
thisResource = thisAttribute.getValue();
thisResourceID = thisResource[0].id;
thisResourceName = thisResource[0].name;
console.log("this resource name=" + thisResourceName)
}
});
var allRows2 = formContext.getGrid().getRows();
//loop through rows and get the attribute collection
allRows2.forEach(function (row, rowIndex) {
var thatRow = row.getData().entity;
var thatRowId = thatRow.getId();
var thatAttributeColl = row.getData().entity.attributes;
var thatResource = "";
var thatResourceName = "";
var thatResourceID = "";
thatAttributeColl.forEach(function (thatAttribute, attrIndex) {
if (thatAttribute.getName() == "new_resource") {
thatResource = thatAttribute.getValue();
thatResourceID = thatResource[0].id;
thatResourceName = thatResource[0].name;
if (thatResourceID == thisResourceID && thatRowId != thisRowId) {
duplicatesFound++;
var msg = "Duplicate resource " + thatResource;
console.log("duplicates found= " + duplicatesFound);
}
}
});
});
});
if (duplicatesFound > 0) {
console.log("duplicate found");
Xrm.Page.getAttribute("new_showduplicateerror").setValue(true);
Xrm.Page.getControl("new_showduplicateerror").setVisible(true);
Xrm.Page.getControl("new_showduplicateerror").setNotification("A duplicate resource was found.  Please remove this before saving."); 
} else {
Xrm.Page.getAttribute("new_showduplicateerror").setValue(false);
Xrm.Page.getControl("new_showduplicateerror").setVisible(false);
Xrm.Page.getControl("new_showduplicateerror").clearNotification(); 
}
} catch (err) {
console.log('Error occurred :' + err)
}
}

这里有一个单独的网络资源，可以触发该功能：

function TriggerSalesQDResourceCount(executionContext){
var formContext = executionContext.getFormContext();
formContext.getControl("s_qd").addOnLoad(GetTotalResourceCount);
}

你知道我该怎么解决这个问题吗？这是新D365第1波更新的已知问题吗？谢谢

这是不受支持(未记录(的代码使用的问题，它将在未来的更新中中断。

不支持：

var gridCtx = formContext._gridControl;

您必须切换到这些受支持的方法。

function doSomething(executionContext) {
var formContext = executionContext.getFormContext(); // get the form Context
var gridContext = formContext.getControl("Contacts"); // get the grid context
// Perform operations on the subgrid
var grid = gridContext.getGrid();
}
