How to pass 2 data model sources to the SearchField

Question

I'd like to pass data from 2 sources to the Searchfield control through parts as in an example here. https://openui5.hana.ondemand.com/#/topic/dfe04650afc046e0802abb1a1a90d2d9

My code:

<SearchField
    id="mySFID"
    enableSuggestions="true"
    search="onSelectDiseaseTerm"
    suggest="onSuggestDiseaseTerm1"
    suggestionItems="{
    parts : [
        {path: 'db2>/SOURCE1/'},
        {path: 'db2>/SOURCE2/'}],
    type: 'sap.m.SearchField'}" >
<suggestionItems>
    <SuggestionItem
            text="{db2>DISEASE_TERM}"
            key="{db2>DISEASE_TERM}" />
</suggestionItems>
</SearchField>

This is failing with the following trace

    Cannot route to target: TypeError: w[b].push is not a function -

SearchField's suggestionItems is an aggregation that takes an array of sap.m.SuggestionItem as input. You cannot pass what you're trying to do.
