Object State inside plugin

Wondered if anyone know if this is possible?

Lets say I update an object type of state with this…

         // update state
            if (update_selected_state) {
                instance.publishState('current_annotation', {
                    "_p_id": id,
                    "_p_name": "alpha",
                    "_p_comment": comment,
                    "_p_author": instance.data.annotation_1_author.trim()
                });
            }

And then later I decide I want to update it again, but ONLY one of those fields whilst keeping the other untouched. Can that be done?

I’ve tried a few ways and I thought sometime back I read somewhere that it could be done but it seems the whole object is required every time.

If I leave the ones I don’t want out of it entirely, like this:

         // update state
            if (update_selected_state) {
                instance.publishState('current_annotation', {
                    "_p_comment": comment
                });
            }

It clears the state entirely, so figured I’d ask the question.

@bubble would you be able to find out?

Cheers

Why not pass the old values with the new value

Yeh I thought of doing that, I just wondered if there was another way. It’s being run as part of an action so I guess I’ll just have to include a field which takes the state value as an input, then change and spit it out again.

Simple answer is no. You can’t ”update” a single field of a whole state. What you can do is republish the entire state, while changing only one field of the objects being published.

Why not store the entire value in an instance and use that to update the state. I don’t have my plugins docs handy but something like this.

instance.data.myState = {
_p_Text: “String”,
_p_Int: 1
}

Then from anywhere in the plugin you can update a value by doing
instance.data.myState._p_Text = “New String”

Then publish it

That would work, why I didn’t think of that at the I’m not sure, thank you Ali.
