i have some problem. i tried applying a style to a BoxComponent in CompositeField.

follow my code

fs = new Ext.form.CompositeField({
                  width: 500,
                  item: [{
                        xtype: 'box',
                        autoEl: {
                                tag: 'img',
                                src: '../image/wave.gif'
                        id: 'wave',
                        style: {
                              top: '7px'
                        xtype: 'displayfield',
                        value: 'look'
So.. my wave image is rendered by absolute position(left attribute '100px', top attribute '0px')
for that reason, i wanna set top attribute to '7px' value. but that code was not applied.
top attribute have returned to initial value(0px). somebody help me!!
