Scrolling a long Form takes a long time on the Nokia E61/E61i/E62		KIJ000636
Overview	-
Reported against	S60 3rd Edition Nokia E61, Nokia E61i, Nokia E62
Category	Java
Subcategory	MIDP1.0/2.0
Date identified	May 10, 2007

Detailed description	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, e.g., 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.
