-------------------------------
Summary: camera.getPicture() calls both the success and error
callbacks when a picture is taken.
Key: CB-621
URL: https://issues.apache.org/jira/browse/CB-621
Project: Apache Callback
Issue Type: Bug
Components: BlackBerry
Affects Versions: 1.4.0, 1.7.0
Environment: BlackBerry PlayBook v2.0.
Reporter: Wayne Fisher
Testing on a 2.0 Playbook, I saw both of my callbacks (success and error)
called when a picture was successfully taken and returned to my app.
The problem appears to be here:
{code}
cameraAPI = {
execute: function (webWorksResult, action, args, win, fail) {
if (action === 'takePicture') {
blackberry.media.camera.takePicture(win, fail, fail);
return retAsyncCall();
}
else {
return retInvalidAction();
}
}
},
{code}
The second parameter to WebWorks takePicture() is defined to be
"onCameraClosed". It appears that onCameraClosed is called after the onCaptured
(the first parameter) callback is called.
I was able to achieve the documented behaviour for camera.getPicture() by
modifying the above code to the following:
{code}
cameraAPI = {
execute: function (webWorksResult, action, args, win, fail) {
var pictureTaken = false;
if (action === 'takePicture') {
function success( picture ) {
pictureTaken = true;
win( picture );
}
function cameraClose() {
if( !pictureTaken ) {
fail( "User canceled operation." );
}
}
blackberry.media.camera.takePicture(success, cameraClose, fail);
return retAsyncCall();
}
else {
return retInvalidAction();
}
}
},
{code}
I would expect that this issue also affects the use of the takePicture method
as used in the Media APIs.
I tested with PhoneGap v1.4.0. The code example from above is from v1.7.0rc1
which is implemented virtually the same as v1.4.0.
