Linking presentations

Until now, we used fixed values in the presentation properties. We will now link properties to parameters.

To do this, we will create an array of strings that is filled with the operating system names and link them as a list for selection, as follows:

  1. Edit the InstallFreshVM workflow.
  2. Add a new array of strings in the attributes and name it GuestOS. Enter Windows 7 and SLES 11 as values.
  3. Now, click on Presentation, select the vmGuestOsName, and add the Predefined list of elements property.
  4. The property looks a bit different. For starters, it's yellow, which indicates that it's a linked property. Click on Help editing OGNL, Linking presentations.
