if the value of a column is the same as the columns default value, eg, 0, it is not displayed in the table data view.
Based on my tests we have problems with default values equal to 0. kexi_fields.f_default is NULL by default but the Default Value property of Table Designer is displayed as 0.
For the record, programmer's info: Default value is problematic property in the Table Designer since it is of mixed type that follows given field's type. I am trying to switch to string now and only convert to the target type when user changes are applied to the design.
The fix will include improvements for entering values: null will be possible to enter.
Adam, based on your idea extra "Set null" button can be added to KProperty. This is functional change so moving the milestone to 3.2.
Setting importance to High for 3.2.0.
