I have created a custom transformer and exposed all external attributes from the input port. I have two attributes, they are called Attribute1 and Attribute2. On the output port, I have set Attribute To Output to Specified Attributes Only. Now I can select/unselect attributes from the list. I have unselected Attribute2 and pressed Ok but the settings don't work. Both attributes are still present outside of the custom transformer on its output port.

 

When I reopen the properties of the output port, both attributes are still selected. But now I cannot unselect them anymore. They are greyed out although Specified Attributes Only is still selected. It doesn't help to change Attribute To Output to All Attributes and back to Specified Attributes Only. When I restart FME, the attributes are not greyed out anymore, but it doesn't matter if I unselect attributes on the output port. The settings take no effect when I press Ok.

 

I'm using FME(R) 2022.2.1.0 (20221202 - Build 22776 - WIN64).

Hi @dsign-world​ I have not experienced this, but this sounds like unexpected behaviour and maybe a bug. If you're able to reproduce this it would be helpful if you could submit a support case with a video of this happening. As a workaround, instead of fiddling with the Output of the custom transformer maybe have an AttributeKeeper or AttributeRemover before the Output to only have the desired attributes.

I'm also curious; what version and build number of FME are you using when this happens?

 

Happy to help, Evie

I have added the FME version to my question. I cannot record videos. You can simply reproduce the problem by connecting a Creator, an AttributeCreator and a new Custom Transformer in a new workspace. Can someone else reproduce that problem?
