This can be observed on the demo editable grid http://extjs.com/deploy/dev/examples/grid/edit-grid.html, the user is allowed to enter text of their own in the 'Light' column. However, when focus is moved, the user value is ignored/lost.
[Ver. 1.1-beta2] Collapsible InfoPanel/Accordion - Extension classes :: Later on will make that animate=false only for IE6 using some browser detechtion This could be solved by splitting title to individual letters but I doubt http://extjs.com/forum/archive/index.php/t-6388-p-3.htmlHOME
I having this same problem with a grid I am building. My guess is that the cell loosing focus is happening before the combo's value is set? A stand alone combo works fine. Any thoughts on how to make this work as expected?
