Defined in:
lib/netzke/communitypack/workspace.rb

Overview

A component that allows for dynamical loading/unloading of other Netzke components in tabs. Warning: This component may be not secure enough, as it allows loading any Netzke component at the request from the client (component class has been sent as a paremeter for the deliver_component endpoint). A more secure implementation would white-list the components to be loaded.

It can be manipulated by calling the loadInTab method, e.g.:

workspace.loadInTab("UserGrid", {newTab: true})

  • will load a UserGrid component from the server in a new tab.

Client-side methods:

loadInTab(componentClassName, options) - loads a component in a tab.

* +options+ is an object that may contain the following keys:
    * +newTab+ (boolean) - whether to load a component in a newly created tab (+true+), or in the active tab (+false+, default)
    * +config+ (object) - config for the loaded Netzke component

closeAllTabs - closes all open tabs

Configuration

Accepts the following options:

  • always_reload_first_tab (default false) - reload the first tab each time it gets activated

We store these in component_session atm. May as well be in persistent storage, depending on the requirements
