In a Perspective 8.1.43 application, I have a button used to navigate back to a main application (named MainApp). I use the following code in a button:

url = system.util.getGatewayAddress() + "/data/perspective/clients/MainApp"  
system.perpective.navigate(url=url)

I have two gateways, one for production and the other for development. The development gateway is not licences.

I can navigate to the MainApp if the application is executed on the Production Gateway but it won't work if the application is executed on the Development Gateway.

It seems the problem is with system.util.getGatewayAddress() and there is no trace in the log.

Any idea why?

Extremely unlikely to be Trial status. Try logging the URL to see if it contains what you expect.

Thanks for the answer. I coinfirm that the URL is ok. The two gateways are configured the same way and contain the same projects and structure. I can navigate correctly on the Standard gateway.

Are you sure the target project is **enabled** on the dev gateway? (If you manually key in the url, does the target project open?)
