Genero Application Server 2.40 New Features

Previously, the GAS could accept parameters from the url with GET method. Starting with version 2.40, the GAS can also handle submit parameters with POST method. When using the POST method, parameters passed to application are not visible in the url for the end user. In your configuration file, the "AllowUrlParameters" setting must be set to "TRUE".

Performance improvements on the GAS have been made to provide you with a better experience using Genero Web Applications.

• Less memory consumed for GWC rendering
• Less data traffic for tables and windows
• Better stack management in threads

With the Silverlight theme, the layout has been reviewed for better compliance with the GDC and a better implementation of the Model-View-ViewModel (MVVM) pattern concept. The layout proportion (widgets size, widgets redesign after window resizing, and so on) is closer to the layout proportion in GDC.

With the Silverlight theme, frozen columns are now supported. Users preferences for tables columns (hide, show, move, sort, size, frozen) are saved in the stored settings.

With the Silverlight theme, textedit with textFormat html now displays a toolbox with classic editing actions (bold, italic, underline, font size, and so on).

The Silverlight theme provide a user-friendly download window. The user can see the list of files to download, choose where to save them, display them or interrupt the download.

The Silverlight theme provides support for type ahead inputs. Type ahead refers to the ability to move to the next natural field (through the use of a tab or mouse click), even though the client is waiting for feedback from the server. In other words, even if the communication between your browser and the server is slow, pressing 'tab' will put the focus in the next field and the user can fill the form without waiting for the server. A rollback mechanism will be run in case of error, or if the natural field flow is not respected (NEXT FIELD ...)

For example, a user enters a value in the field, which must be validated on the server. After the user enters the value, the Tab key is pressed and the cursor will move to the next natural field and allow input. The server, meanwhile, is validating the data. If the data does not pass validation, the rollback mechanism returns the user to the field with the issue to allow the user to fix the error in question, displays an error message, and removes any data entered while in type ahead mode.

The DUA_HTML5 output map is provided as a preview set. It is designed to run on modern desktop browsers as well as on mobile browsers. It will likely suffer some limitations at this early stage.
