Refresh of data

[ericlee1974]

I am trying to get this working in a component that is called from a set of search filters, which retrieves the data from a http call.
The first call sets the Node[] and the table data is displayed, but on subsequent calls to the component, the data is refreshed, but the table does not reload the new data.

Is this achievable?

Edit - I can see some work has been done on this in Fix #24
