Hello everyone!
I'm stuck on this issue .
I have a case with a subgrid with service activities. Each Service Activitiy is considered a visit on my scenario. Whenever a Service Activity is completed i want to decrease by one a field on my form called Remainining Number of Visits
Here is the code i'm using :
function DecrementNumberOfVisits() {
var packageGrid = Xrm.Page.getControl("ServiceActivities").getGrid();
var packageRows = packageGrid.getRows();
var rowCount = packageRows.getLength();
var remainingVisits = Xrm.Page.getAttribute("ral_remainingnumberofvisits").getValue();
if (rowCount != 0) {
for (var i = 0; i < rowCount; i++) {
var rowEntity = packageRows.get(i).getData().getEntity();
var listStatus = rowEntity.getAttributes().get("statuscode").getValue();
if (listStatus == "Closed")
{
remainingVisitsts = remainingVisits - 1;
}
Xrm.Page.getAttribute("ral_remainingnumberofvisits").setValue(remainingVisits);
Xrm.Page.getAttribute("ral_remainingnumberofvisits").setSubmitMode("always");
}
}
}Whenever i try to run this code i get this message :
TypeError: Cannot read property 'getValue' of null at DecrementNumberOfVisits
Can anyone help me why this is happening ? I tried to use another field other than statuscode and still doesn't work. I also tried to use getText and i again get the same message.
