SAPUI5 PlanningCalendar - binding two entities - odata

I have the following problem:
I'm developing an APP using the flameworks PlanningCalendar, but I have two EntitySet:
Salas(3):
CAPACIDADE: 6
ID: 3
NOME: "SALA 3"
NavReservas: {__deferred: {…}}
__metadata: {type: "room_sfsf.rooms.SalasType", uri: "https://leandrp822648trial.hanatrial.ondemand.com:443/room_sfsf/rooms.xsodata/Salas(3)"}
__proto__: Object
__proto__: Object
and:
Reservas(1):
DATA_FIM: Tue Sep 18 2018 14:00:00 GMT-0300 (Horário Padrão de Brasília) {}
DATA_INICIO: Tue Sep 18 2018 12:00:00 GMT-0300 (Horário Padrão de Brasília) {}
ID: 1
ID_SALA: 3
NOME: "caio"
USUARIO: "caio.amorim"
__metadata:
type: "room_sfsf.rooms.ReservasType"
uri: "https://leandrp822648trial.hanatrial.ondemand.com:443/room_sfsf/rooms.xsodata/Reservas(1)
"
but I can not get the two to appear on the screen, but I can not get the two to appear on the related screen, Below is the view file:

The function import is missing in the metadata of odata (odata created via CDS)

I want to create a function import in odata for use in sapui5 application. I create CDS view, add BOPF, create action SEND_MAIL, add annotation to odata. But function import tag is still missing in the metadata, i dont know why. And Exporting type in action inactive. Determination working, action not. What i do wrong?

I solved the issue by choosing the exporting type in the actions list and reactivate the bopf

RESTier OData Function that support $expand and $filter

With the help of the RESTier team, I manage to create an RESTier function that return a list of my entity.
Here's the code
protected EdmModel OnModelExtending(EdmModel model)
{
var ns = model.DeclaredNamespaces.First(); // PointLoc.Data
var entityContainer = (EdmEntityContainer) model.EntityContainer;
var locationEntityType = (IEdmEntityType) model.FindDeclaredType(ns + "." + "Location");
var locationEntitySet = entityContainer.FindEntitySet("Locations");
var locationEntityTypeReference = new EdmEntityTypeReference(locationEntityType, false);
var locationEntityCollection = EdmCoreModel.GetCollection(locationEntityTypeReference);
var ambilLocationsByMarketId = new EdmFunction(ns, "AmbilLocationsByMarketId", locationEntityCollection, false, null, true);
model.AddElement(ambilLocationsByMarketId);
entityContainer.AddFunctionImport("AmbilLocationsByMarketId", ambilLocationsByMarketId,
new EdmEntitySetReferenceExpression(locationEntitySet));
return model;
}
And here's my implementation on the Controller
[HttpGet]
[EnableQuery]
[ODataRoute("AmbilLocationsByMarketId")]
public IQueryable<Location> AmbilLocationsByMarketId()
{
var locations = DbContext.Locations.Where(l => l.Name.Contains("Hotel")).Select(l => l);
return locations;
}
It works fine returning the list of data with i send a HTTP GET to
http://localhost:21922/odata/AmbilLocationsByMarketId
but when I try to add $expand or $filter, It's not working.
http://localhost:21922/odata/AmbilLocationsByMarketId?$expand=Category
I'm Error that reads like

Why destructor of an extended binding is not called when extending binding is removed?

Creating a XulRunner application for Windows I found that if binding B extends binding A. And B is being removed, then only destructor of B is called, not followed by a call of A's destructor.
Is there something wrong with my code, or this is a XulRunner bug (I haven't find matching bug in bugzilla)?
Here is an example that I tested on XulRunner 23 and 35:
main.xul:
<?xml version="1.0"?>
<?xml-stylesheet href="chrome://global/skin/" type="text/css"?>
<window id="main" title="My App" width="500" height="300" sizemode="normal"

<script><![CDATA[
function print(aString) {
document.getElementById("log_msg").value += aString + "\n";
}

function callF(aId) {
document.getElementById(aId).f();
}
]]></script>
<vbox flex="1">

I know that it is a hack in fact but it works.

How do I get an attribute using the 'amazon-ecs' gem?

I am using Amazon Product Advertising API (amazon-ecs) gem, but I am using the item_lookup method instead of item_search, which is the only one documented.
I am looking to return the item TradeInValue but I am confused as to how to do that. It is clearly being returned, but I am not sure how to parse it.
This is the call:
Amazon::Ecs.item_lookup('9780521153348', :response_group => 'ItemAttributes', :id_type => 'ISBN', :search_index => 'Books')
And this is the return, which I am not sure what to do with. The methods in amazon-ecs don't seem to work for item_lookup and XPath isn't working either:

Okay, I figured it out. I was trying to treat item_lookup as a single return value, rather than a hash the way search is returned.
item_lookup is basically the same as item_search:
res = Amazon::Ecs.item_lookup('9780521153348', :response_group => 'ItemAttributes', :id_type => 'ISBN', :search_index => 'Books')
res.items.each do |item|
puts item.get('ItemAttributes/TradeInValue/FormattedPrice')
end

"An item with the same key has already been added" error when calling Context AddObject

Can somebody please help me with this error. I have an ASP.NET WebApp, within the Entity Model I have an entity called tb_AdminUser, with a UserID property as GUID. This is also the Entity Key. The entity is not in any relationship with any other entity. I get the error when calling the AddObject() function.
In my code I call the following...
SQL2008R2_824852_leapdbEntities temp = new SQL2008R2_824852_leapdbEntities();
tb_AdminUser au = new tb_AdminUser();
au.UserID = Guid.NewGuid();
au.Username = "TEST";
au.Password = "pete#webinspired.net";
au.LockedOut = false;
au.Surname = "Feehan";
au.Forename = "Pete";
temp.tb_AdminUser.AddObject(au); //error occurs here
temp.SaveChanges();
The EDMX XML Code is as follows
<EntityType Name="tb_AdminUser">
<Key>
<PropertyRef Name="UserID" />
</Key>
<Property Name="UserID" Type="uniqueidentifier" Nullable="false" />
<Property Name="Forename" Type="nvarchar" Nullable="false" MaxLength="50" />
<Property Name="Surname" Type="nvarchar" Nullable="false" MaxLength="50" />
<Property Name="Username" Type="nvarchar" Nullable="false" MaxLength="50" />
<Property Name="Password" Type="nvarchar" Nullable="false" MaxLength="50" />
<Property Name="LockedOut" Type="bit" Nullable="false" />
</EntityType>
