I have a map attribute that holds the following map<string,list<SObject>> I want to iterate over the map and pass the list down to a child component but keep getting an error.

This is what I have so far:

Parent component

<aura:attribute name="mapOfThings" type="map" />

<aura:iteration items="{!v.mapOfThings}" var="m">
        <childComponent listOfThings="{!m.value}"/>
</aura:iteration>

Child Component

<aura:attribute name="listOfThings" type="list" />

<aura:iteration items="{!v.listOfThings}" var="l">
        {!l.name}
</aura:iteration>

When the component loads I get the following error:

Uncaught Assertion Failed!: Unable to get value for key 'm.value'. No value provider was found for 'listOfThings'. : false

I can make it work if I didn't have a child component but in this scenario I must have them separate

    Is {!m.value} a list? What does your data look like? – sfdcfox Jul 17 '18 at 22:57
  • Assume you meant map<string,list<SObject>> based on your question, so have made that update in your question. If not, please make necessary changes. – Jayant Das Jul 17 '18 at 23:10
  • @JayantDas yes I did, must of overwritten it! thanks – JPG Jul 18 '18 at 8:19

I had a typo in my child component and was referencing {!m.value} again, hence the error!
