DateUtils error

Postby Harjo » Wed Jun 06, 2018 12:25 pm

Hi there,

we use the DateUtils solution inside our solution, to calculate weeknumbers,
so far so good.

But most of the time, when we open our solution, and the weeknumber is touched in on of our calculations, we get this error:

Code: Select all
jun 06, 2018 12:12:33 PM com.servoy.j2db.util.Debug error
SEVERE: error executing calc: weeknumber
java.lang.RuntimeException: Exceptie bij het uitvoeren van berekening: weeknumber van tabel quotes, fout org.mozilla.javascript.EcmaError: ReferenceError: "calendar" is not defined. (core_DirectManager/scopes/DateUtils/getWeekOfYear#14)

Caused by: org.mozilla.javascript.EcmaError: ReferenceError: "calendar" is not defined. (core_DirectManager/scopes/DateUtils/getWeekOfYear#14)

if we look this up inside the DateUtils scope, we see this:

Code: Select all
* A java.util.Calendar instance used to do the math
* @private
* @properties={typeid:35,uuid:"6FEE1C0C-ECD0-4E98-A5BA-5420B77D0917",variableType:-4}
var calendar = java.util.Calendar.getInstance();

* @properties={typeid:24,uuid:"A92A0657-35C4-4ECC-8F5C-8A7D2C5C0CBF"}
function getWeekOfYear(date) {
   return calendar.get(java.util.Calendar.WEEK_OF_YEAR);

So somehow, the first time, var calendar is not initialized somehow...
How do we make sure, that this global scope is initialized before we touch a function inside a calculation?
