Table - setVisibility to Component

Hi all.

I’m working with table with (for example) 4 columns. Label, ComboBox, CheckBox and again Label. The ComboBox contains for example 2 choices: Test and Other. When user choose Other the CheckBox in that row will be invisible and when i choose Test the CheckBox will be visible. Here is the code:

Problem is that when i choose Other and next time i choose Test the CheckBox is still invisible. (the debugger show that the property visible on the CheckBox component is set on correct value (true or false) but the Table don’t show it.

Do you know what to do or which way can i go to solve this problem?
