I am trying to use "lightning:input" components (still in beta) but I encounter an issue when the component is firing the onchange event :

Something has gone wrong. Underlying raw object [object Object] does not support property: currentTarget
Failing descriptor: {c$testComponents$controller$sayHello}.
Please try again.


<lightning:input type="text" value="test" name="inputText" label="Input" onchange="{!c.sayHello}"/>


sayHello : function(component, event, helper) {

Does anyone have a workaround which works with this component ?

Thank you !

Thanks for bringing this up. This is a known problem that is currently being worked on. In the meantime, you can work around the issue by binding a change handler to the value attribute:

<aura:attribute name="value" type="String" />
<aura:handler name="change" value="{!v.value}" action="{!c.onValueChange}" />
<lightning:input type="text" value="{!v.value}" />
  • Thank you Eugene. ( I'm sad we don't have an updateOn attribute anymore because this workaround is only working with keyup events on text inputs...) Do you you have a link where we can track the fix for this ? Oct 25, 2016 at 17:07
  • Hey Lucas--what use case is this workaround not working for? Oct 25, 2016 at 23:29
  • If I want my action to only be triggered on blur instead of keyup with input text for example Oct 26, 2016 at 15:40
  • This Doesn't work if your lightning:input tag is inside aura:iteration@EugeneKashida

I have faced some errors before too and I find it generally easier to work with event.getSource() which returns the input component. On it you can use the usual get method on components:

<lightning:input type="text"
                 onchange="{! c.onChange }" />
onChange: function(component, event, helper) {
    const inputName = event.getSource().get('v.name');
    const inputValue = event.getSource().get('v.value');
    // ...
