Problem with IWRegion, controls disappear after first use

[GruizR]

Hi everyone,

I have a problem with an IWRegion that contains an IWGrid and 2 buttons, this IWRegion is shown when the user selects an option from a list contained in an IWComboBox, information is displayed in the grid, the problem is that when they close that IWRegion and select another option, the IWRegion appears empty and the controls within it are not visible.

Can you help me, please?

How is the IWRegion closed? What option is selected? How?
You need to show me some code or preferable give me a minimal test case showing this behavior.
