CORRECTION:

ISSUE 9307 should be referenced instead of 9037. I made a typo in the original notes;

===============================================

As the reporting user indicated in bug 9307, the offending code appears to be:

Current Code

manage_proj_ver_copy.php

foreach ( $t_rows as $t_row ) {
if ( version_is_unique( $t_row['version'], $t_dst_project_id ) ) {
version_add( $t_dst_project_id, $t_row['version'], $t_row['released'], $t_row['description'], $t_row['date_order'] );
}
}

Proposed Code [on issue 9037]

manage_proj_ver_copy.php

foreach ( $t_rows as $t_row ) {
if ( version_is_unique( $t_row['version'], $t_dst_project_id ) ) {
version_add( $t_dst_project_id, $t_row['version'], $t_row['released'], $t_row['description'], db_date($t_row['date_order']) );
}
}

I fixed with this piece of code.. in version_api.php

change line 132 to:
$c_date_order = db_timestamp(db_date( $p_date_order ));
from the original:
db_timestamp( $p_date_order );

i hope this help..

This problem persists with 1.1.4.

The first copy operation sets the version dates to 1222, if you copy these copied version entries again, it doesnt work at all, as there seems to be an underflow and a DB columns gets null, which leads to an exception.

Confirmed that proposed fix by Artgroup was insufficient to resolve issue. Please re-evaluate proposed solution above <a href="http://www.mantisbt.org/bugs/view.php?id=9307">0009037</a>

I can confirm that this issue is solved in Mantis v1.1.5 by the proposed fix from JCW in note (0019419) above:

====================================================================
manage_proj_ver_copy.php

foreach ( $t_rows as $t_row ) {

if ( version_is_unique( $t_row['version'], $t_dst_project_id ) ) {

version_add( $t_dst_project_id, $t_row['version'], $t_row['released'], $t_row['description'], db_date($t_row['date_order']) );

}

}

Credit for finding the bug should go to mgstm who originally reported the issue on issue # 9307.

Targetting for 1.1.6. This fix should also be ported to the development branch as well.

Fixed in GIT trunk
