How to pass a published parameter into a custom transformer

Hi @saqibamin, you can create a published parameter in the custom transformer definition with the same way to create a published parameter in the workspace. The published parameter defined in the custom transformer will appear in the transformer GUI as a new parameter for the transformer.

You can then pass the published parameter directly to the custom transformer via the new parameter.

I had the same issue, late I've found that you have to unchceck "Disable Attribute Assignment" in user parameters management of Custom transformer workspace (see image). Later zou can assign this parameter to "global" user parameters in the main workspace.
