--------------------------------
Summary: inconsistent null handling between EVAL and ONLINE bridge
modes
Key: CB-12218
URL: https://issues.apache.org/jira/browse/CB-12218
Project: Apache Cordova
Issue Type: Bug
Components: Android
Affects Versions: 6.0.0
Environment: Android
Reporter: Alan Kinzie
If the Android native code invokes the success callback like this:
callbackContext.success(null);
then the value given to the javascript callback changes depending on the bridge
type used.
If the ONLINE_EVENT type is used, then null will be passed to the javascript
callback.
ie: if result is the parameter of the javascript success callback then
result === null // will be true
result === "" // will be false
If the EVAL_BRIDGE type is used, then an empty string will be passed to the
javascript callback.
ie: if result is the parameter of the javascript success callback then
result === null // will be false
result === "" // will be true
The value of the parameter given to the success callback should not change
depending on the bridge type. Since ONLINE_EVENT was the default before
cordova android 6.0.0, I am inclined to think the ONLINE bridge is doing the
correct behaviour. Also, converting null to an empty string loses information.
Therefore I think the EVAL mode should to be changed to be consistent with the
ONLINE mode.
