CoordinateSystemSetter get error when use Conditional Value option?

It’s working for me. 

Can you share what the error is that you’re getting and how you have set up the conditional value?

I just have a simple test as follows:

And I have tried some conditional value at test statement but always get error:

“CoordinateSystemSetter (CoordinateSystemFactory): CoordinateSystemSetter: Invalid Test Expression: TEST@Value(_creation_instance)=1”

“CoordinateSystemSetter (CoordinateSystemFactory): CoordinateSystemSetter: Failed to evaluate input expression: FME_CONDITIONAL:DEFAULT_VALUE''BOOL_OP;OR;COMPOSITE_TEST;1;TEST@Value(_creation_instance)=1'LL-WGS84'FME_NUM_CONDITIONS2___”

“Error running translation: CoordinateSystemSetter: Invalid Test Expression: TEST@Value(_creation_instance)=1. CoordinateSystemSetter: Failed to evaluate input expression: FME_CONDITIONAL:DEFAULT_VALUE''BOOL_OP;OR;COMPOSITE_TEST;1;TEST@Value(_creation_instance)=1'LL-WGS84'FME_NUM_CONDITIONS2___”

It only works with fixed-value coordinate systems:
 

That’s really strange. So yesterday when I said I tried it, I had used a User Paramter rather than an attribute value. Trying to recreate what you have and I’m getting the same errors.

Some things to look out for:

• If you let the Creator create just one feature, it’s _creation_instance will be 0. I changed that in the conditional value, no change.
• You’re currently creating a null geometry, I thought that that might throw the CoordinateSystemSetter off, but adding geometry doesn’t make a difference.
• You’re not adding a coordinate system to the Else part, I also tried that and no difference.

I also tried your setup but with a user parameter and that doesn’t work either all of a sudden...

I think you’re right and this may be a bug. Your best course of action is to submit this as a support ticket with either your local partner or Safe directly and refer them to this discussion.

I just tested it in 2026.1 and 2026.2:

in 2026.1 it worked fine
In 2026.2 I am getting the same errors, also in CoordinateExtractor
 

CoordinateExtractor_SPECIFIC_Z_ROUTER (TestFactory): CoordinateExtractor: Invalid Test Expression: TEST@Value(Test)=5


Conditional values in other transformers (e.g. localCoordinateSystemSetter, Bufferer, CoordinateRounder,AttributeManager) work fine

So it indeed looks like a bug to me

edit: ​@redgeographics  this time you beat me by a minute
Easiest workaround would be a TestFilter and then multiple CoordinateSystemSetter with fixed values for now.

I have submitted this to Safe as a support ticket!  Hopefully it will be fix in the next version. 😀
