Start a GAS app from GWA

The runOnServer front call allows you to start an application via the Genero Application Server (GAS) from a Genero Web application (GWA).

A runOnServer call is basically implemented as described for Genero Mobile for iOS (GMI) and Genero Mobile for Android™ (GMA) applications in mobile.runOnServer; however, there are two notable differences or things to consider when implementing runOnServer calls in a Genero Web application:

  1. In GWA, unlike for GMI/GMA, both RUN and RUN ... WITHOUT WAITING can be used in any combination.

    If we wanted to limit it to a RUN, the GBC would need to know if it is in a runOnServer state.

    The runOnServer application finishes when the GBC loaded with the remote application detects application termination (meaning the session ended).

  2. In the GWA, you can omit the full origin (http://host:port) in the GAS URL argument, because the origin of the starting GWA application and the GAS application must be the same. (A Cross-Origin Resource Sharing (CORS) issue could arise, but this would require a modification in the GBC). Therefore, the call for the GAS URL argument can be reduced to a simple path like /ua/r/simple. In GMI/GMA, this is not possible because the native application always runs on another origin.
