Examples with ClientWindow jakarta.faces.lifecycle.ClientWindow used on opensource projects

Example 1 with ClientWindow

use of jakarta.faces.lifecycle.ClientWindow in project myfaces by apache.

the class FlashImpl method _clearRenderFlashTokenIfMapEmpty.

    // is we can reduce the session size a bit.
