Unable to use Date Object in Script Task

Hi,When I try to use a Date object (javascript) in a script task I get the following exception:–com.vaadin.event.ListenerMethod$MethodExceptionCause: com.vaadin.event.ListenerMethod$MethodExceptionCause: org.activiti.engine.ActivitiException: coudn't deserialize value 'sun.org.mozilla.javascript.int

Try fully-qualifying the "new Date()" -> "new java.util.Date()", as "new Date()" is a javascript-type…

Thank you, that worked better!

Now I need to convert the date to ISO-8601 format to use it in a TimerCatchingEvent, as Time date.
In the same script task as before, I tried using:

var timeDate = tD.toISOString();

but got the following exception:

I've tried different browsers (that are supposed to support Date.prototype.toISOString) but I get the same exception every time.

Is there another way to convert a date object to ISO-format for use in the TimerCatchingEvent?

Thanks,
caiw

You could write a java-class that does this and instantiate it from JavaScript or alter the ScriptBindings, activiti uses to expose additional java-objects on top of the process-variables that are present now…

And by the way, the Javascript is executed on the server, so it doesn't matter what browser you use to access the Vaadin-app anyway…
