Perspective table what is, cause scripts don't think it's a dataset

So I used the control to add a line of bogus data so the columns would show up, when I do this:

unitList = caller.getSibling("Units")
ds = system.dataset.clearDataset(

I get an error thrown that isn’t a dataset. I’ve tried toPyDataSet but it tells me it’s not a dataset as well. Not sure how to work with the tables data.Thx, jake

You didn’t specify what this component is or how its is populated so I’ll pretend it’s a Dropdown using a Named Query on the property. In the binding you can specify the return format and it sounds like you want a dataset.


So it’s a perspective table, I’m not sure what a query binding is or how it’s used. Can it be attached to anything?Thx, jake

I changed it to an array on the component, which I guess it was already and changed the code to use python array .append to fill the array, now it’s giving me a component error. I’m sending in json with a value and style.

data = [{“value”: value from a tag, “style”: path to a style in project},
{“value”: value from a tag, “style”: path to a style in project},


ds.append(data) = ds


Could you provide a screenshot?
Could you provide the actual code, as opposed to the pseudo-code you provided? Pseudo-code is the absolute worst thing to provide when you’re encountering an error in your code.
