URL: https://github.com/apache/incubator-kie-tools/issues/3648
In the KIE Sandbox I am executing a DMN Model that passes an input `Foo` of
type `number` to a Context Boxed Expression named `Baz`. In the Context I refer
to the input `Foo`, and I try to handle null:
```
Bar: if Foo
= null then 0 else Foo
result: Bar
```
When I click **Execute** in the KIE Sandbox, and do not enter a value for
`Foo` angebe, then my context is not evaluated, and I see the error message
**Required dependency 'Foo' not found on Node 'Baz'**.
It appears this happens because the execution form in the sandbox does not
send `null` for empty inputs of type number:
```
{
"Foo": null
}
```
Rather, it sends an empty object to /jitdmn/dmnresult:
```
{}
```
Is there a way to send null as input value for an input of type number in
the Sandbox execute form? Changing the Language of my Bar expression to B-FEEL
does not help.
Note: If I switch the type of `Foo` to `Any`, the Sandbox form sends an
empty string to the extended services, which also does not seem quite right - I
would have expected the form to send `null` for an empty string field as well.
