Combobox missing dropdown button (v-filterselect-button)

version: Vaadin 7 beta9

I have a page with a series of ComboBoxes. I fill the comboboxes with Strings of varying length and some of the boxes end up missing their dropdown button. Firebug inspection shows that the box is actually too large for it’s contanier and the button is actually just obscured.

See the attached screenshots for visual details.

I’m wondering how I can prevent this from happening. As you can see in one of the screenshots, the longest string in the ComboBox’s element list is still much shorter than the width of the ComboBox itself so I’m not sure why it’s width is being set as wide as it is.

The ComboBoxes are layed out like:

±----------------- VERTICAL LAYOUT ------------------------------+

+---------------  HORIZ LAYOUT -----------------------+
   LABEL          LABEL        ComboBox   Button
 -----------------------------------------------------------------

+---------------  HORIZ LAYOUT -----------------------+
   LABEL          LABEL        ComboBox   Button
 -----------------------------------------------------------------

+---------------  HORIZ LAYOUT -----------------------+
   LABEL          LABEL        ComboBox   Button
 -----------------------------------------------------------------

±------------------------------------------------------------------------------+
