displaying ssize_t value in table cell

Hello,

I want to display a number of type ssize_t in a numeric table cell. In the UI editor, the cell has been set to intptr_t.

Running the code in debug64 works fine, in debug I receive the error message:

FATAL RUN-TIME ERROR:   Invalid argument type: found 'int', expected '__int64'.

I have to add: in the UI editor I have created the table with one row only, I add more rows programmatically using InsertTableRows (but the cell types should be inherited). The error only shows up when filling the cell of the last row.

Ideas?
