In the Navigation section of the Home-tab, it is possible to manage all ‘navigation points’. Navigation points are basically menu options that are available in the various menus that are available in a WEM application. A navigation point points towards a specific flowchart or URL. This is defined when you create a navigation point.
Every WEM application comes with three different menus:
- Main menu – this is the menubar that you find at the top of your application
- User menu – this menu is also on the top menubar, but at the far right: here you find all navigation points (menu options) that are available when a user has logged on.
- Footer menu
The way these menus look, is controlled by the project’s Master Template. The actual location of a menu is also controlled by the master template. E.g., the Main menu could appear on the left hand side if that is what the Master template dictates.
Besides the menus that are mentioned above there is also a ‘menu’ called
invisible. This is a special one: all navigation points that are part of
Invisible are URLs that a user can use directly via a browser. These URLs then access the WEM application for some specific functionality. A godo example is a URL to reset a password: you get a URL that is very specific, you can’t access the functionality via the application directly, but through the URL you could access the password reset functionality of the application.
A navigation point points directly to a flowchart or a hyperlink. Usually a navigation point is used as a menu item in a menu.
When you click on a menu you get access to the navigation point management. You get a menubar to manage the navigation points:
New navigation point
To create a new navigation point, click on the menu where you want to create a navigation point.
When you create a new navigation point, some properties have to be defined:
|Name||The (internal) name of the navigation point.|
|Display text||(optional) This is the text that is used for a menu item (navigation point). If this property is left empty, the
|Icon||(optional) It is possible to have menu items that also include an icon. Here you can specify the icon.|
|Flowchart||Only available when the
|Hyperlink||Only available when the
|URL Path||Only available when the
|Open hyperlink in||When you use a hyperlink as a navigation point, you can specify what should happen when the hyperlink is opened: Open in a new window, open in the current window, open in the current frame or open in the parent frame.|
|Visible when||You can restrict access to a navigation point, by specifying an expression. If this expression evaluates to
Properties, Move, Delete, Find usages
Most Navigation menubar options are pretty straightforward:
Propertiesbrings up the property form for a navigation point, so you can see/edit the current properties;
Moveallows you to move a navigation point to another menu;
Deletedeletes the navigation point;
Find usagesshow you where a navigation point is used within the current project.
Edit query parameters
Query parameters are parameters that are used in URLs. Let’s look at this URL:
This URL points to the navigation point “queryparam”and contains two parameters: uid and action. Both have values associated with them. If this URL was actually used, the flowchart that is associated with the navigation point “queryparam”, has direct access to these variables and their values. To make a parameter available to a navigation point, select the navigation point and click on
Edit query parameters. You now get a form where you can manage the parameters for this navigation point:
You can now add or delete query parameters. When you
Add a new paramaters, you have to select the field to which this parameter should be mapped:
The WEM modeler automatically assigns a name to the parameter, but when you click on that name you can change it to your own preferred name (this is the name that is used in the URL).
When you want to change the data field, simply click on
Change data field.
Let’s, look at the WEM Modeler Ontology.
