Hi,
I know what's the error in my application (I'm such a fool): I working
with multiple classes, and one class included an WTable* who was
initialized in constructor.
On first load anything was ok, but if I show another WWidget, the
WTable* was deleted (as child-object of root). And if I go back to the
Widget which included the WTable*, it doesn't created it new. So anytime
the Application crashed (sure) and anytime I saw the Wt internal error.
Maybe this can help you?
Greetings
Torsten

Hey Torsten,

Hi,
I'm using Witty 2.99.0 - and sometimes I become following error:
Wt internal error: TypeError: j55 is null, code: undefined, description:
undefined
Maybe it is my application, but how I'm able to find out where it is?
This is almost certainly an error in Wt (unless you are using
stateless slot learning or writing JavaScript handlers).
The reason is that Wt assumed the existence of a particular dom
element, but it doesn't exist in the web page. What you could do to
help us solve the problem is use firebug's console to see in the
JavaScript strack-trace which DOM element corresponds to the j55
variable (usually defined a few statements before the error) and
figure out the widget that corresponds to this DOM element (e.g. you
could use setObjectName() and setId() to related widgets to DOM
elements).
As soon as you get it reproduced in a test case, you may send it to me...
Regards,
koen
