I have an application I am building for ADA compliancy and utilizing the 4 Accessibility Extension objects. Created buttons for navigation between reports and tabs. Used the properties as described in the documentation to set the Actions
Select Action: External - Set Variable
Variable Name: vDataSection
Variable Value: 5
These setting are supposed to navigate to a different set of report. I testing the functionality of the objects with out the use of the mouse, so I tab to the specific button and hit the space bar as recommended. Button show appears to accept the space bar, but does not fire off the requested action as designed.
