Is there any possibility in "Component SDK Development" to fire events in contribution.ztl?


I'm developing a "Component SDK" for the Lumira Designer. We have a component with an event "onLoad", which should execute some custom Design Studio script.

I know, we can fire this event from client javascript using fireEvent("onLoad"). However, I'm just wondering if there is any simple solution to fire this event from server side (in contribution.ztl).

A workaround is to change a component property in a ztl method, which triggers the component setter on the client side, where we can call fireEvent("onLoad"), which finally results in a server roundtrip again...

As we start on the server side and end on the server side, this way (server-client-server) seems to be unnecessary.

So, is there any possibility to fire events in contribution.ztl on server side?

    Events are not supposed to be fired from a ZTL function. Although ZTL functions are executed on the server side, they are always called from the client side. Even if it were possible to trigger an event within a ZTL, how were you expecting to trigger the ZTL function from the server side? This is not possible.

    I understand your concern about unnecessary server round-trips but this is the way Lumira Designer has been architected so you must develop your SDK component accordingly.

    In any case, I would have thought that it makes more sense to trigger an "onLoad" event from the client side because presumably this should occur when the component is initialised or rendered.

    • Hi Mustafa,

      yeah, that's a good point. I was just wondering if there is a possibility that I do not yet know, apart from a real scenario.

      But you are right, there are other ways and possibilities to develop the SDK component according to the architecture.

      Thank you.
