Re: Invalid conversion error when using TEXT datatype in INPUT

Hmm - I think there is a problem with validation check - its trying to
convert to a string so it can run some checks - but I'm really not sure it
needs to run those on blobs..

I've committed the change to CVS - if you can try that and let me know if
you're still having compilation issues - I can try to fix those too..

If you just want to make the change on your own local source - try adding
the "if" test in lib/libui/ui_curses/ioform.c :


int
A4GL_check_and_copy_field_to_data_area (struct s_form_dets *form,
                                        struct struct_scr_field *fprop,
char *fld_data, char *data_area, int var_dtype)
{
  int pprval;
  int dsize;

// Add these 3 lines
  if ((fprop->datatype & DTYPE_MASK) == DTYPE_BYTE || (fprop->datatype
&DTYPE_MASK) == DTYPE_TEXT) {
        return 1;
  }


and see how you get on..
