Edit multicolumn listbox or table header while VI running
As this issue has been risen on LAVA, I checked and didn't find it reported yet.
The issue is when one wants to edit the multicolumn listbox' column or row headers while a VI is running.
By setting the Edit Position property to {-1,0}, it should be possible to edit the first column header. Instead, the {0,0} cell is selected. This behavior occurs also with row headers. The detailed help specifically says that -1 edits the headers and that it's a writable property settable while the VI is running.
The same error occurs with "Table". The only difference is that for tables, there is a "Editable headers" property that needs to be set to TRUE. If false, the edit position returns {-2,-2} as expected. However, when true, it returns {0,0} similarly to multicolumn listbox.
As a side note, I couldn't find the property to programmatically set the value of Table.Property.Editable headers. It is available through right-click on the control, but not found in property list. Perhaps I didn't dig enough?
