Scrolling a long Form (100+ items) takes a long time, especially during changes between different elements, e.g. ChoiceGroup to TextField, and from similar elements with different formatting constraints.

For example, from a TextField.URL masked field to a TextField.PHONENUMBER masked field.

According to the MIDP specification, class javax.microedition.lcdui.Form javadoc:

"Notes for Application Developers:

Although this class allows creation of arbitrary combination of components the application developers should keep the small screen size in mind. 
Form is designed to contain a small number of closely related UI elements."

Therefore, in order to avoid this problem, use other forms of displaying large amounts of content, such as custom items, combined with search and paging algorithms.

How to reproduce

The attached application FormScrollingTest can be used for testing this issue.
