15Hi,
In a customized business process flow (on a single entity) I want the user to confirm when moving backwards in the BPF. It's a reminder that he/she has to redo a lott of stuff before progressing again.
I would like you use the new API onPreStageChange but haven't got it working in JavaScript. I followed Richards' example linked below. The big change is that I don't want to abort the execution and notify the user, I want the execution to wait untill the users decides.
The code basically looks like this:
The first function is called onLoad of the form
function registerOnStageChangeEvents(executionContext) {
formContext.data.process.addOnPreStageChange(myPreStageChangeChecks);
formContext.data.process.addOnStageChange(throwalertfunction);
}
function myPreStageChangeChecks(executionContext) {
console.log("I started a state change!");
var formContext = executionContext.getFormContext();
var process = formContext.data.process;
var eventArgs = executionContext.getEventArgs();
var currentStageId = process.getActiveStage().getId();
var nextStageId = process.getSelectedStage().getId();
var sourceId = executionContext.getEventSource();
var confirmStrings = {
cancelButtonLabel: "Cancel",
confirmButtonLabel: "Continue",
subtitle: "Are you sure?",
title: "Confirm leaving stage",
text: "Choices have consequences"
};
var confirmOptions = {
height: 150,
width: 260
};
if ((currentStageId != nextStageId) || eventArgs._direction === 1){
eventArgs.preventDefault(); // block everything
Xrm.Navigation.openConfirmDialog(confirmStrings, confirmOptions).then(function(success){
if(success.confirmed){
console.log("go on...");
formContext.data.process.movePrevious(); // try to start again
} else {
console.log("aborting");
}
}, function(error){
console.log(error);
});
return;
}
}
The problem is that by blocking all events (eventArgs.preventDefault();), I need to start the stage change again, but that call (formContext.data.process.movePrevious();) will trigger the onPreStageChange() again, building a loop.
If I don't stop the execution, the dialog is opened, but in the background the stage change continious.
How can I fix this? How do I 'insert' a asynchronous action (like waiting for user input) in the onPreStageChange?
Many thanks!
