Key values change after popup call [message #7330]

Hi Tony,
after a popup call in a upd1 pattern the key values are changed. I want to insert the key values from the popup form as a foreign key. In the _cm_popupReturn function the key values in the $fieldarray as well as the values in the $select_array are fine. In my debugger I see that when returning the values from _cm_getForeignData in std.table.class.inc the key values are changed. Is it because I have the same names as key fields?
I attached the two dict files in the attachment in one file.

When you return from a popup the default behaviour is for the column values in $select_array to be inserted into $fieldarray. This will cause the values for existing fields in $fieldarray to be overwritten regardless of whether they are part of the primary key, a candidate key or just foreign keys. If the fields being returned have one name, but you want to change them to another then you should do so in the _cm_popupReturn() method.

The _cm_getForeignData() method is designed to perform lookups on foreign key fields in order to retrieve additional data.

Now I understand and it works fine. The only thing I had to do was to change the values in $select_array into the original values (from $fieldarray) before returning $fieldarray at the end of the _cm_popupReturn() method. Thank you.
