The undo operation did not completely undo a relationship between two tables. It removed only the line drawn between two tables, but did not undo the fields and keys. (Bug #36645)

Double-clicking a column-heading separator in Find results caused a crash. (Bug #36266)

Forward Engineer wizard failed to create a table, but did not show any error messages. (Bug #35874)

Saving a file restores the column widths of the list view to default under Physical Schemata. (Bug #35718)

When making a column a primary key and this column has NULL as default value, this default value is not changed. When the table gets synchronized back to the database Workbench creates a statement such as:

ALTER TABLE `test_defhan`.`table1` CHANGE COLUMN `id_table1` `id_table1` INT(11) NOT NULL
DEFAULT NULL, ...

This leads to an error:

Error 1067: Invalid default value for 'id_table1' (Bug #32972)
