Correction, the error seems to be caused by this function....
static void SelectViewLoadTable(FormPtr frm)
{
Word row;
Word recordNum;
Word lineHeight;
Word dataHeight;
Word tableHeight;
Word lastRecordNum;
Word numRows;
ULong uniqueID;
FontID currFont;
TablePtr table;
VoidHand record;
RectangleType r;
table = GetObjectPtr(SelectTripTableTable);
TblGetBounds(table, &r);
tableHeight = r.extent.y;
currFont = FntSetFont(SelectFont);
lineHeight = FntLineHeight();
FntSetFont(currFont);
dataHeight = 0;
recordNum = tblInfoTopRecord;
// For each row in the table, store the record in the table item
// that will display the record.
numRows = TblGetNumberOfRows(table);
for(row = 0; row < numRows; row++)
{
// Get the next record in the current category.
record = DmQueryNextInCategory(gInfoDB, &recordNum,
dmAllCategories);
// If the record was found, store the record number in the table
item,
// otherwise set the table row unusable.
if(record && (tableHeight >= dataHeight + lineHeight))
{
TblSetRowID(table, row, recordNum);
TblSetItemStyle(table, row, 0, customTableItem);
TblSetItemFont(table, row, 0, SelectFont);
TblSetRowHeight(table, row, lineHeight);
DmRecordInfo(gInfoDB, recordNum, NULL, &uniqueID, NULL);
if((TblGetRowData(table, row) != uniqueID) ||
(!TblRowUsable(table, row)))
{
TblSetRowUsable(table, row, true);
// Store the unique id of the record in the row.
TblSetRowData(table, row, uniqueID);
// Mark the row invalid so that it will draw when we
call the
// draw routine.
TblMarkRowInvalid(table, row);
}
lastRecordNum = recordNum;
if(row + 1 < numRows)
recordNum++;
dataHeight += lineHeight;
}
else
TblSetRowUsable(table, row, false);
}
// Update the scroll arrows.
SelectViewUpdateScrollers(frm, lastRecordNum);
