I have a sap.m.List component where invoke a list of OData objects. This object have others object inside it. For this reason, I use expand parameter for accessing to propertis of intern object. But when I put multiples objects on "expand" parameter, list component doesn't work:
This way doesn't work:
<List id="lstRequest" headerText="Custom Content"
items="{
path: '/Requests',
parameters: {
expand: ['RequestTypeDetails', 'UsersDetails']
}
}"
>
<StandardListItem
title="{RequestTypeDetails/RequestType2} - {RequestCode}"
description="{TotalAdvance}"
icon="sap-icon://request"
iconDensityAware="false"
iconInset="false"
type="Navigation"
press="onSelectApprovation" />
</List>
This way works:
<List id="lstRequest" headerText="Custom Content"
items="{
path: '/Requests',
parameters: {
expand: 'RequestTypeDetails'
}
}"
>
<StandardListItem
title="{RequestTypeDetails/RequestType2} - {RequestCode}"
description="{TotalAdvance}"
icon="sap-icon://request"
iconDensityAware="false"
iconInset="false"
type="Navigation"
press="onSelectApprovation" />
</List>
I don't know how especific when I need to use multiples objets on "expand" parameter.
Thanks for your help!
UPDATE 1
The solution give for @Nabi looks working...But I'm not secure because I call elements of list on a detail page.
I create a JSONModel object with element of list and then invoke this object on detail page:
var itemJSONModel = new JSONModel(itemObject, false);
this.setModel(itemJSONModel, "detailView");
But in my detail page I can't see value of UsersDetails properties (Users is an object inside item object. UsersDeails is the name of NavigationProperty):
<Input fieldGroupIds="datos_suscripcion" value="{detailView>/UsersDetails/UserName}"
placeholder="Usuario..."
id="inUsuario"/>
EDIT 2
This is OData model of item object:

</EntityType>
Use a simple comma separated string:
<List
id="lstRequest"
headerText="Custom Content"
items="{
path: '/Requests',
parameters: {
expand: 'RequestTypeDetails,UsersDetails'
}
}"
