JS Number  is a double according to the specification. ScriptableWidget

See the sample I recently committed.
   



Ok, I had a look at it. woody_flow_example.js (v2) contains lines like

   wid.account.value = 2;

   wid.cowheight.value = 2;

with datatype long and it seems to work. I did remote debugging and the Double

is replaced by a Long in the method jsSet_value(Object value).



But I'm not using the v2, but "normal" Woody and it seems not to work. The

ScriptableWidget here has a similar logic in put() as in the mentioned

jsSet_value() in v2. But setting a breakpoint inside it, it never breaks there.

 

That's because the object provided to your event handler in your form 
definition is not a ScriptableWidget but rather the Java Widget. When 
you write

   offsetWidget.value = 0

you're actually calling Widget.setValue() through Rhino's Java integration

Is it now just a new functionality in v2 or is something broken in the current

Woody ScriptableWidget?

 

The old ScriptableWidget has something similar but as I mentioned in my 
email about the new one it has other limitations that makes it unusable.

BTW, this functionality does only work for fields, but not for output widgets

(it's more or less obvious from the code and I tried it with v2 sample). 

I just added a fix for Output.
