TypedSDK: Collection of issues

[cpyrgas]

For now will keep one ticket for many issues and will keep updating it. Can later decide to divide in to multiple ones or not.

1. ComboBox:FillUsing( {"one","two","three"} ) results to an exception:

TestTypedSDK_FillUsing.zip

System.InvalidCastException: Unable to cast object of type 'ObjectCollection' to type 'System.Collections.Generic.IList`1[System.Object]'.

Also not calling FillUsing() at all results to a similar exception when showing the window:

System.InvalidCastException: Unable to cast object of type 'ObjectCollection' to type 'System.Collections.Generic.IList`1[System.Object]'.

Ahh, indeed I should had included a sample. Original problem is fixed, but now a new exception is thrown in this code:

System.InvalidCastException: 'Unable to cast object of type 'XSharp.VO.SDK.VOComboBox' to type 'XSharp.VO.SDK.IVOListBox'.'
ACCESS __List AS IVOListBox
		RETURN (IVOListBox) oCtrl

Here's a sample in VS, just run and open the HelpAbout dialog, which contains two ComboBoxes, on with no items fillet at all and the other filled with an array. The exception happens in both of them
