Using List Drop-Down lists in table views

Hi all,

I have a table view in my model which has 2 fileds: Material and Unit of Measure. The Unit of measure field is declared as a Drop-Down List and gets it's values though a Dynamic list, using a function that returns the available units of measures of the selected lines' material.

When the user clicks and selects a value, then it dissapears from the screen. It only reappears if he selects a different line and then return back to line he was before!

Is there a solution or a workaround for this problem?

I would appreciate any help.
