Recently, I wanted to merge two maps into one, but I did not find an appropriate function, so I wrote the following myself.

private Map mergeMaps(Map _map1, Map _map2)
{
    Map retMap;
    MapEnumerator mapEnum;
    // Initate first map from second map if empty
    if( !_map1)
    {
        _map1 = new Map(_map2.keyType(), _map2.valueType());
    }
    // Check compatibility
    if(_map1 && _map2)
    {
        if(_map1.keyType() != _map2.keyType() || _map1.valueType() != _map2.valueType())
        {
            throw error(Error::wrongUseOfFunction(funcName()));
        }
    }

    retMap = _map1;
    mapEnum = _map2.getEnumerator();
    while(mapEnum.moveNext())
    {
        if( !retMap.exists(mapEnum.currentKey()))
        {
            retMap.insert(mapEnum.currentKey(), mapEnum.currentValue());
        }
    }
    return retMap;
}

Have you ever wondered how Dynamics AX builds up this window for employees when moving the mouse over the name of an employee?

This is caused by the PreviewPartRef property of a table, which allows you to quickly create preview windows.

The following steps are necessary:

• Create a form
• Create a form part, which points to above form
• Create a (Display-)Menu item which points to the form part
• Enter the name of the menu item in the poperty PreviewPartRef of the table

For example, I created a simple form for the CustGroup table and included it as described above.

Without my customization, the preview usually looks as follows:
