Syntax Error raised in phonegap-1.3.0.js in FR-FR locale when watching the
accelerometer
----------------------------------------------------------------------------------------
Key: CB-141
URL: https://issues.apache.org/jira/browse/CB-141
Project: Apache Callback
Issue Type: Bug
Components: WP7
Affects Versions: 1.3.0
Environment: All phone configured to use the FR-FR locale (the
emulator included)
Reporter: David Rousset
Assignee: Jesse MacFadyen
There is a bug in the Accelerometer.cs file of the WP7GalClassLib library in
the way to formats the current coordinates into JSON format.
Here is the kind of output produced on a FR-FR locale (and on any locale using
the coma character as the separated character for numerics) :
"{\"x\":0,00472,\"y\":-0,19879,\"z\":-0,98115}" instead of
"{\"x\":0.00472,\"y\":-0.19879,\"z\":-0.98115}" for EN-US.
The JSON.Parse() instruction then raises a Syntax Error exception later on due
to the bad formatting of the JSON string.
To fix the bug, the code of the GetCurrentAccelerationFormatted() method needs
to be changed by this one:
private string GetCurrentAccelerationFormatted()
{
string resultCoordinates = String.Format("\"x\":{0},\"y\":{1},\"z\":{2}",
accelerometer.CurrentValue.Acceleration.X.ToString("0.00000",
CultureInfo.InvariantCulture),
accelerometer.CurrentValue.Acceleration.Y.ToString("0.00000",
CultureInfo.InvariantCulture),
accelerometer.CurrentValue.Acceleration.Z.ToString("0.00000",
CultureInfo.InvariantCulture));
resultCoordinates = "{" + resultCoordinates + "}";
return resultCoordinates;
}
It adds the usage of CultueInfo.InvariantCulture available in the
System.Globalization namespace to always have the same formatting whatever the
locale is.
