Upgrading from a previous version of Jiwa 7 to 7.00.157 appears to have changed the type of the line User 1, User 2 and User 3 fields. This is impacting custom plugins.
They are not actually integer fields. The display on the grid is to 0 decimal places now by default (unintended side affect of other changes to the grid control) but the underlying datatype in the tables is still DECIMAL(19,6). A plugin can set the desired precision and attached is a plugin which sets the decimal precision on sales orders and quotes to be the local currency decimals.
