Table 1. General
Overview Reference

You can run Genero 2.11 applications in GDC 2.21, and your application behavior will be the same as in GDC 2.11.

This can be useful if you need to mix FGL 2.11 and 2.2x installations; you only need to install GDC 2.21.

See the GDC 2.21 upgrade guide.

The internal HTTP stack has been rewritten to support and restore pre-2.20 features like Kerberos Support, NTLM Single Sign-On, or Client certificate.

No additional reference.
The GDC can resend the http request when a network error occurs. While available in previous versions, it now can retry in more situations (such as an HTTP error 500). See Connection configuration options.
Table 2. Windows
Overview Reference

With prior versions, The GDC automatically displayed scrollbars around the form when the window size is larger than the desktop size and the GDC is maximized.

This feature now works when the window is not maximized. When the window is larger, GDC will automatically resize the window to the size of the desktop (height or width) and display scrollbars around the form.

This feature should be used carefully. A Desktop application is not a web application, and having scrollbars (especially horizontal ones) around the form is not common. As GDC will try to always show the current field, this may lead to lots of scrolling when you move from one field to another if the fields are not all visible.


Adapt your forms to the smallest desktop size you target. Automatic scrollbars should only appear for "accident" cases.

To avoid automatic scrollbars when a window is not maximized, use the formScroll style attribute:
<Style name="Window.myWindow">
  <StyleAttribute name="formScroll" value="no">
The action panel (menu/dialog) has been reviewed to achieve automatic scrollbars, resulting in a slightly different look; however, the main behavior remains the same.
  • Navigation button differ when on the first or last row.
  • A "plus" button has been added to display all remaining items with a single click.
  • An animation shows the scroll direction.
For information on windows and window presentation styles, see the Genero Business Development Language User Guide.

As well as "maximized", windows can be started minimized. Set the windowState style attribute to minimized.

For information on window presentation styles, see the Genero Business Development Language User Guide.

DateEdit now has a presentation style named "showCurrentMonthOnly". This style configures whether the calendar shows only the current months, or displays (in light grey) days of the previous and next month.

Table 5. Monitor
Overview Reference

The Connection tab now displays both the application name and text.

Users now receive an error message if the number of user licenses is exceeded. User Limit exceeded is now a default terminal string, so the end user has feedback if the application can't start because of a license issue.

No additional reference.

Debugging information has been added to the debug console when a shortcut starts. Analyzing this log may help you to understand what GDC did, and why a connection may have failed.

No additional reference.

GDC 2.21 has been adapted to work with WinSSHd 5.0.9 (some changes in the server have been done by Bitvise too, so you'll need to upgrade the server part to at least version 5.0.9.)

Table 8. Experimental features
Overview Reference
It is possible to see a Flash application in the pages you display with the Integrated browser.

This feature uses "Netscape Plugin" technology, which is also used by Mozilla Firefox™ or Google Chrome. So you need to have Firefox, Chrome plugin or stand-alone Adobe™ flash player installed. Having Microsoft™ IE plugin only is not enough.

Compositing allows you to make some fancy effects with window transparency.

See Presentation styles.

Supported added for a Command Link Button using the buttonType button style attribute.

See the Button style attributes topic in the Genero Business Development Language User Guide.
Two new frontCalls have been added in the standard frontCall library:
  • storeSize asks GDC to store the current size of the current window.
  • restoreSize asks GDC to restore the stored size.
See Standard front calls in the Genero Business Development Language User Guide.
Experimental features are available in the product, but:
  • They are likely to be changed in future versions, or even simply removed from the product.
  • They are not supported. Four Js will not be able to fix all reported issues. This is frequently due to current technical limitations.
  • They may not work 100%, not on all platforms, and likely not with all Front-Ends.
