ExtJS 4.1.1.a - Keyboard navigation issue at TreePanel

[talha06]

Hi,

I'm facing keyboard navigation problem with TreePanel. Here's my treepanel configuration:

rootVisible: false,
animate: true,
autoScroll: true,
useArrows: true,
border: true,
singleExpand: true,

Finally I put the tree as a single item of window; then show it.

I can't use keyboard arrows to expand/collapse items.

Is this a bug or am I missing something?

Any helps will be appreciated a lot.
Thanks in advance.

I found the solution, the problem for my situation was setting selType as rowmodel. After I comment out it, keyboard navigation works as expected..
