sap.m.Select - Bind key as Integer

I am using sap.m.Select as a select option for a user and it looks like this:

<Select
    forceSelection="false"
    selectedKey="{Priority}"
    items="{
        path: '/PRIORITY_DDSet',
        formatter: '.formatter.convert',
        sorter: {
            path: 'Value'
        }
    }"
>
    <core:Item
        key="{
            path:'Id',
            formatter: '.formatter.convert',
            type: 'Integer'
        }"
        text="{Value}"
    />
</Select>

As a model, ODataModel is used. The problem is: when change on the sap.m.Select happens, the string key is bound to the OData model like this:

enter image description here

However, the definition of the OData model states, that Priority should be of type Integer.

As you can see in the definition of the Select, I tried to use formatter for the key as well as the type Integer. I also tried to use sap.ui.model.type.Integer as a type but without success. I checked, and the formatter function is called only when loading the Select. When selection is changed in the Select, the formatter function is not called.

Is there a way to do this in XML? Or do I need to code this e.g. in selection changed event?

Solution

  • Remove formatters and add type: 'sap.ui.model.type.Integer' to selectedKey:

    <Select 
    forceSelection="false" 
    selectedKey="{path: 'Priority', type: 'sap.ui.model.type.Integer'}"
    items="{ path: '/PRIORITY_DDSet', sorter: { path: 'Value' } }">
    <core:Item 
        key="{path:'Id'}" 
        text="{Value}"/>
</Select>

    I'm not sure if that's the reason but value of the Priority property can be used without any extra coding like type conversion to save with e.g. ODataModel.submitChanges()
