Issue in piwik.js function logEvent #13165
Description
If you call the function
logEvent(category, action, name, value, customData, callback)
without parameter it shout gives an error.
(logConsoleError(‘Error while logging event: Parameters category and action must not be empty or filled with whitespaces’);
But it doesn’t. Because the line
if (trim(String(category)).length === 0 || trim(String(action)).length === 0) { ...
will not work. String(category) returns always 9 (the length of the word undefined) when categorie is empty
So the error will never been showed.
