Component inside table disappears when scrolling

I have a table with a column of components that inherits from HorizontalLayout , they are composed by 3 embedded and a textfield, in the first load no problem, but when scrolling, some of the components from the column dissapear presenting the white cell, the other elemnts in the row load without problem, this not always happen , i have checked with firebug and the components are not there,
any ideas of why is this happen?? thnx anyway, and sorry for my bad english.

I too faced with such an issue when I used HTML formatted Label components as Table columns. However, I was not able to reliably reproduce it.
Do you have a test case to reproduce this behavior?
