Can anyone please help me in this?
My initial Use Case Scenario was to display a list of records in a lightning component, and providing the ability for users to update the same records. This was a simple implementation by using an aura attribute with type as list of sobject records.
But Later the ask changed to show the same records in a categorized manner, say all records of Type A must appear first, followed by all records of Type B, much like a summarized report where we create a grouping based on some field.
To achieve that, I had to create a wrapper class in my controller, and instead of using List of sObject, I had to use List of Wrapper class in my Lightning component to display the records accordingly.
The display part was over. I achieved it. Yay!
But the issue that came up was editing the records. The records were no longer updating.
For updation, On the click of Save button, I pushed the List of Wrapper back to the controller for updation. But, there is some unknown Exception firing up each time I click on Save button for updation of records in the Apex Class.
When I debug the List returned by the component from the controller, it appears to be in a suspicious format.
Can anyone please help me in an approach for updating the records. My code is as below :
Lightning Component Code :
//DocList1 is the attribute for type List of wrapper class and used to display the records.
<aura:attribute name="DocList1" type="DocumentListController.DocumentListWrapper[]" description="store wrapper class records list"/>
// Js Controller : Save is the method that runs on Save button click
({
initRecords: function(component, event, helper) {
// call the apex class method and fetch sub stage of loan appliction record
alert('Modification in progress');
var action = component.get("c.fetchSubStage");
action.setParams({
'loanId': component.get("v.recordId")
});
action.setCallback(this, function(response) {
var state = response.getState();
//alert(state);
if (state === "SUCCESS") {
var capturedResponse = response.getReturnValue();
console.log('Response received'+capturedResponse);
console.log(JSON.stringify(capturedResponse));
// set SubStage attribute with return value from server.
component.set("v.subStage", capturedResponse);
}
});
$A.enqueueAction(action);
// call the apex class method and fetch account list
var action = component.get("c.fetchDocuments");
action.setParams({
'loanId': component.get("v.recordId")
});
action.setCallback(this, function(response) {
var state = response.getState();
//alert(state);
if (state === "SUCCESS") {
var storeResponse = response.getReturnValue();
console.log('List received'+storeResponse);
//component.set("v.DocList", storeResponse);
console.log(JSON.stringify(storeResponse));
// set AccountList list with return value from server.
component.set("v.DocList1", storeResponse);
}
});
$A.enqueueAction(action);
},
Save : function(component, event, helper) {
//console.log('DocList'+component.get("v.DocList1")[0].lstDocumentCheckList[0].Id);
var action = component.get("c.saveLoan");
action.setParams({
"listOfDoc": component.get("v.DocList1")
});
action.setCallback(this, function(response) {
//alert('12121');
if (response.getState() === "SUCCESS" && component.isValid()) {
component.set("v.DocList1", response.getReturnValue());
component.set("v.showSaveCancelBtn",false);
}
//window.location.reload(true);
});
$A.enqueueAction(action);
}
})
And finally the controller class goes as follows : //saveLoan is the method for updating the records, but the Unknown Exception is thrown in Salesforce, Right after the System.debug statement for displaying the list.
public class DocumentListController {
// method for fetching the Sub Stage of the Loan Application record.
