i used height: 100%; and width: 100%; for all my views in sencha touch but % height is not working in ExtJs when tablet is rotated from horizontal to vertical. if i keep the tablet in vertical position and refresh page then height adjust itself to maximum but when i rotate from hotizontal to vertical then view does not expand to maximum height. i have to refresh again and then height of view fix itself to maximum height in vertical position of tablet. why is that i have to refresh page to see view fixed in maximum height with %. Is that known issue in ExtJs?
