Why does debugger say that the documented OpenLaszlo lz.FocusService.getFocus() method doesn't exist

The lz.Focus reference manual documentation for the latest official release (4.9.0) of the OpenLaszlo programming platform (http://www.openlaszlo.org/lps4.9/docs/reference/) gives many examples of calling methods on the lz.FocusService object, however, many of the examples do not work:

eg: 

lz.FocusService.getFocus();

Calling this command responds in the following debugger window error:

TypeError: Error #1006: getFocus is not a function.

Why do I get this error trying to use it?

Solution

  • The OpenLaszlo 4.9.0 reference manual documentation is confusing. Calling the lz.Focus object (instead of lz.FocusService) with the same method names seems to work.

    eg:

    lz.Focus.getFocus();

    This does not give an error.
