Server: Unable to write to node of type "Variant"

I'll have to look into whether that should be possible or not. You can write "anything" to a node of type Variant - you just have to encapsulate that anything in a Variant first.

edit: Doh... you probably did that as you wrote the String. I think you're right about this.

That is what should happen .. at least I think it is.

So on the client side I am doing something like write ( new DataValue ( new Variant ( "String" ) ) )

On the server side it pops up like in the following screenshot:

So the original value is the DataValue, from there the Variant and then the String.

Or do you mean I should put a Variant inside the Variant?

[kevinherron]

You can't put a Variant in a Variant - I think you're right about this being a bug. I should be able to fix it pretty quickly, but I also want to write some kind of test case for it.

Yes I just saw that:

checkArgument(clazzIsArray || !Variant.class.equals(componentClazz), "Variant cannot contain Variant");

Since it currently does block me, I can work on a fix if you like.

[kevinherron]

Sure, in that block you've breakpointed in, you'll need to add a check to see if expected is Variant, and if so, allow the write to proceed.

If you could start a unit test for AttributeWriter that would be good too - you could just test this case for now.

[ctron]

Alright then ... yes, you are right. A unit test seems to be a good way to start.
