Hi,

On product Info Window, deactivate the "IsInstanceAttribute" column.
When you try to select a product (eg: to add it on SO line), it will throw an error as the column cannot be found.

See InfoProductWindow, line 360 :
Object value = contentPanel.getValueAt(row, findColumnIndex("IsInstanceAttribute"));
It cannot be found and it crashes.

Not aware of all consequences of this (I'm not using it), but code should be changed to something like :

m_PAttributeButton.setEnabled(false);
int colIdx = findColumnIndex("IsInstanceAttribute")

if (colIdx > 0) {
Object value = contentPanel.getValueAt(row, colIdx);
if (value != null && value.toString().equals("true"))
m_PAttributeButton.setEnabled(true);
}

Regards,

Nicolas
