is it possible to call another App (openApp? spawnApp?) from one Lianja App and then return to the original App by continued its running? Is parameterized call possible? In this case, in which delegate can the parameters be received?

Hi Strato,

Yes, see the Lianja system object methods here: https://www.lianja.com/doc/index.php/Lianja#Methods

See sessionstorage also.

An interesting use of sessionStorage is the ability to switch between Apps and maintain state or pass data between them.
So, when building a large application which is built out of smaller Apps and each App is built out of pages, you can load Apps using Lianja.openApp("someappname") and in the "Ready" delegate read some data from sessionStorage that was set using Lianja.sessionStorage.setItem("mediate", "some JSON encoded object") in the parent App that loaded "someappname".
This technique also works in the Web/Mobile client which also has Lianja.sessionStorage in the framework.

Whats the difference
between spawn and open?

[barrymavin]

Lianja.openApp("app name") opens the specified app replacing the existing one. (desktop, web and mobile).

In desktop apps only, Lianja.spawnApp("app name") runs the specified app in the background in runtime mode. In other words in runtime mode you can have multiple windows open each with an app. You can use shared memory between each of the apps and change state in each of them as required by your application logic. This is NOT for development mode use.
