[resolved] clear context value

richie1985 — Wed, 12 Nov 2014 17:42:34 GMT

hi,
since version 5.6.0 i cant delete values in a context variable.
when i try to delete anything i will set the old value back
how can i set it to empty so that my "if(!context.datum.equals(""))" will work again?

Thx!
Erik

At first empty is not cleared, it is simply an empty string. null would be a reasonable initial value.
Is the datum field a Date or a String?
In case of String I would ask:
if (context.datum.isEmpty() == false)

okay than in other words:
how to set a empty string in context variable?

context.datum = "";

But it is mostly not a clean way to set an empty string. I would set it to null or to any reasonable value. What do you are trying to solve with the empty string?

hi,
make sure you're not trying to modify a 'context group' value directly in context view.
if not , it's not a normal behavior.

context group? no its a normal context variable. when you create one its empty. BUT when you set value you CANT delete this value, you can only set a other value....
