Resetting the catalog.

[PhillipsOwen]

I have been experimenting with this iframe example of catalog loading with the goal of populating the catalog programmatically using a web service (json). I am noticing that reloading the data catalog object can produce duplicate members.

Is there a way to remove the data object (client side) before a reload of catalog data is initiated?

I have a proof of concept .html page that i can share (upon request).

Thanks!

Hi @PhillipsOwen. Does this problem still occur if each entry in the catalog is given an id property?

[PhillipsOwen]

Thanks so much for the response!

there is an id for every catalog as well as member definitions. note there can be multiple catalogs in a response from the DB, each with a set of member layers.

here is an example data file. this file represents the output of a DB stored function call that that is loaded into terria by a parent frame.
