-----------------------------------
Summary: Search on Contacts ‘id’ field with JavaScript number type
crashes in iOS
Key: CB-11975
URL: https://issues.apache.org/jira/browse/CB-11975
Project: Apache Cordova
Issue Type: Bug
Reporter: Andrew Forrest
I was trying to retrieve a specific contact by id in my Ionic/Cordova app, so
used the following code:
{code:javascript}
return Contacts.find(
['id'],
{filter: contactId, multiple: true})
{code}
However, this crashes the iOS app at runtime with:

Seems to only fail when {{contactId}} is a JavaScript number. Converting it to
a string before searching ({{contactId+""}}) works fine.
Fault originally occurred because Contact {{id}} field in iOS is an integer…
and it looks like I’m getting a JavaScript number value out of the Contacts
API. Was storing this integer in SQLite (which preserves the data type),
getting an integer back out, and passing it back into the {{Contacts.find()}}
API.
Suggest:
* Contacts {{id}} field is supposed to return a string, so it should return a
string on iOS
* {{Contacts.find()}} should coerce its arguments to correct types before
calling native code.
