[jira] [Updated] (CB-9102) Crash when using a iOS Cordova plugin
within a WebSocket event
[ https://issues.apache.org/jira/browse/CB-9102?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Iñaki Baz Castillo updated CB-9102:
-----------------------------------
Description:
I've coded a cordova plugin for iOS. It is exported as a JavaScript object with multiple functions in `window.cordova.plugins.iosrtc`.
If I use any of those exported functions within the callback of a WebSocket event (onopen, onmessage, etc), the plugin/app usually crashes:
