Hey,
I would like to clarify some things. The flowable-task and flowable-modeler application do not share the same DB tables. Which means that if you deploy an app only to flowable-task then you won’t see the models in flowable-modeler.
If flowable-rest and flowable-task are configured with the same DB, then they should have the exact same data, which means that if you deploy to flowable-rest then you should be able to see it in flowable-task.
Have a look at the Flowable UI Modeler section of our documentation. There are 2 ways to export an app. One export creates a zip which can be used for importing an app to other flowable-modeler application. And the second one exports a bar which should be used for deploying to the engines.
Cheers,
Filip
