I’m using FMW Reader to read and analyze FME workspaces, and I have a question about custom transformers.

There is an attribute called Custom Parent Name. When this field exists, it shows me the connection to the custom transformer inside it. However, how can I determine whether that specific custom transformer is enabled or disabled in the main FME workspace?

For example, suppose an FME workspace contains multiple instances of the same custom transformer, such as:

  • LineDivider

  • LineDivider_2

  • LineDivider_3

The Custom Parent Name attribute may contain only LineDivider, without the _2 or _3 suffix.

In this case, how can I distinguish which specific instance of the custom transformer the connection belongs to?

More specifically, how can I reliably identify:

  1. The exact instance of the custom transformer in the main workspace.

  2. Whether that specific instance is enabled or disabled.

  3. The relationship between the transformer instance and its Custom Parent Name, especially when multiple instances of the same custom transformer exist.
