Hi,

I am using a lightning:datatable to display data-
 <lightning:datatable columns="{!v.columns}"
                             data="{!v.data}"
                             keyField="id"
                             errors="{!v.errors}"
                             show-row-number-column= "true"  
                             onrowselection="{! c.getSelectedRow}"/>

Using a button to validate the data before it gets updated in salesforce.
Sending a response back to helper in Map<Id, String> -

response- {"a1Fn00000007AEpEAM":"This contact is already assigned as an Emergency Contact, choose a different contact and save","a1Fn00000007AEoEAM":"This contact is already assigned as an Emergency Contact, choose a different contact and save","a1Fn00000007AF9EAM":"This contact is already assigned as an Emergency Contact, choose a different contact and save","a1Fn00000007AF8EAM":"This contact is already assigned as an Emergency Contact, choose a different contact and save","a1Fn00000007AFTEA2":"This contact is already assigned as an Emergency Contact, choose a different contact and save","a1Fn00000007AFSEA2":"This contact is already assigned as an Emergency Contact, choose a different contact and save"}

As per lightning documentation, lightning:datatable attribute error shoudl be set in following format-
cmp.set('v.errors',
{ rows:
{ b:
{ title: 'We found 2 errors.',
messages: [ 'Enter a valid amount.', 'Verify the email address and try again.' ],
fieldNames: ['amount', 'contact'] }
},
table:
{ title: 'Your entry cannot be saved. Fix the errors and try again.', messages: [ 'Row 2 amount must be number', 'Row 2 email is invalid' ]
}
});

I am not sure how to iterate over a map to set error attribute in this format. Any help will be appreciated.

Hi All,

I am trying to create a simple calculator performing total = quantity * price. But my method written in controller is not getting called. ANy help would be appreciated.

visualforce code-

<apex:page id="ProductCalculator" controller="ProductCalculator">
  <apex:pageBlock id="pbProdCalc">
      <apex:form id="fProdCalc">
          <apex:dataTable id="dtProdCalc" columns="4" value="{!Products}" var="con" styleclass="list">
