I solved my problem…  
I have deleted and recreated my SqlTagProvider and redone my SqlTags type and now it works.  
the problem appeared when I move and rename my instances.  
Is there a method to purge SQLTags delete the Provider ?  
Thanks,  
Have good day.

Hi,

I think the easiest way to troubleshoot this would be for you to [upload](http://inductiveautomation.com/uploads) your gateway backup to ticket number 7586. That way, I can trace through the parameter replacing, and see why it’s not being applied. If this isn’t possible, let me know and I’ll see what else we can do.

Also, what version are you currently using?

Regards,

hello,  
I just posted my backup with error.  
I am in 7.5.0, but I also tried with version 7.5.1.1110-beta4 with the same problem.

Thanks, I was able to track it down fairly easily.

The problem had to do with the “scope” of parameter overrides. In your case, on the instance that don’t work, you’ve overridden some parameters of the nested types, but not all of them (and you shouldn’t need to). When it filled in the properties, it didn’t have the value for the non overridden parameter, so they were left as they were.

I’ve committed the fix and it will be available in the next 7.5.1 beta, which should get put up today I think.

Regards,
