i am currently seeing some weird behaviour in a Salesforce flow. The screen flow has got a lightning component in it which is a custom build picklist that updates a Salesforce Picklist when the value is changed. I tested it and the related picklist is really updated by the apex controller when a picklist change occurs.
The lightning component also has a onInit method that gives me the current value of the related picklist. This also works when i update the picklist via the update record element in a flow.
Now comes the odd part: When i update the related picklist from the lightning component via an apex controller and navigate one screen back the value is still in the related picklist but if i navigate again to the next screen the value is gone and the onInit return a null value. (I also checked in the related picklist and it is there gone too). Is the getRecord element of a flow not getting the current values?!
I have absolutely no idea why this is happening. :D Really really looking forward to your answers.
The methods of the lightning component
getCurrentValue : function(cmp, event, helper) {
if(cmp.get('v.recordId') != null && typeof cmp.get('v.recordId') != "undefined" && cmp.get('v.recordId') != ''){
var action = cmp.get("c.getCurrentValue");
action.setParams({
"objectName": cmp.get("v.object"),
"pickListFieldName": cmp.get("v.field"),
"recordId": cmp.get("v.recordId")
});
action.setCallback(this, function(response) {
var state = response.getState();
if (state === "SUCCESS") {
cmp.set("v.defaultvalue", response.getReturnValue());
this.fillPicklist(cmp, event, helper);
}else{
alert("Es gab ein Problem mit Ihrer Internetverbindung.");
}
});
$A.enqueueAction(action);
}else{
this.fillPicklist(cmp, event, helper);
}
},
updateRecord : function(cmp, event, helper) {
var action = cmp.get("c.updateObject");
action.setParams({
"objectName": cmp.get("v.object"),
"pickListFieldName": cmp.get("v.field"),
"recordId": cmp.get("v.recordId"),
"updateValue": cmp.get("v.outputvalue")
});
action.setCallback(this, function(response) {
var state = response.getState();
if (state === "SUCCESS") {
}else{
alert("Es gab ein Problem mit Ihrer Internetverbindung.");
}
});
$A.enqueueAction(action);
},
The related apex controller:
@AuraEnabled
public static void updateObject(String objectName, String pickListFieldName, Id recordId, String updateValue){
List<sObject> list_object = Database.query('SELECT Id, ' +pickListFieldName +' FROM ' +objectName +' WHERE Id = :recordId');
SObjectType objectType = Schema.getGlobalDescribe().get(objectName);
DescribeSObjectResult objDef = objectType.getDescribe();
Map<String, SObjectField> fields = objDef.fields.getMap();
for (sObject obj: list_object){
obj.put(pickListFieldName,updateValue);
}
System.debug('updateValue: ' +updateValue);
update list_object;
}
@AuraEnabled
public static String getCurrentValue(String objectName, String pickListFieldName, Id recordId){
List<sObject> list_object = Database.query('SELECT Id, ' +pickListFieldName +' FROM ' +objectName +' WHERE Id = :recordId');
SObjectType objectType = Schema.getGlobalDescribe().get(objectName);
DescribeSObjectResult objDef = objectType.getDescribe();
Map<String, SObjectField> fields = objDef.fields.getMap();
for (sObject obj: list_object){
obj.get(pickListFieldName);
}
System.debug('returnValue: ' +(String)list_object[0].get(pickListFieldName));
return (String)list_object[0].get(pickListFieldName);
}
The screens in the flow where i navigate back and force.
