VALUE TYPE
Since Version 4.7 we support the possibility to define the value type of a property.
With this property, the customizer can control how the property is displayed on the client.
Possible values are:
- Standard (default)
- MinNormMax (supported for string, double and int properties)
- MinMax (supported for string, double and int properties)
Optional Attributes
REFERENCE
Assign a reference if the value of the property should link to an UBIK® object. The data type of the MetaProperty has to be Guid that the data (guid) can hold a reference to an UBIK® object.
- Locate an existing or create a new Reference
- Assign the reference to the REFERENCE property either by
- dragging and dropping the reference object onto the cell
- selecting the desired reference from the dialog appearing after double-clicking the cell
SELECTIVELIST
Assign a selective list to a property, if the respective column should display a Combobox with all items of the list instead of the value field. The value can then only be selected from the list, but not be edited manually anymore.
- Locate an existing or create a new Selective List
- Assign the list to the SELECTIVELIST property either by
- dragging and dropping the list object onto the cell
- selecting the desired list from the dialog appearing after double-clicking the cell
UNITITEM
If the property should consider a Unit (for example Ampere, Volt, etc.) the underlying MetaProperty has to incorporate a Unit Item either by
- dragging and dropping the unit item object onto the cell
- selecting the desired unit item from the dialog appearing after double-clicking the cell
 | Only properties of type Double can posses measuring units! |
FORMAT
INDEXCOUNT
Set the number of named index keys, for example to 4.
INDEXKEYS
Enter the index keys as a comma separated list of strings, for example "a,b,c,d" (INDEXCOUNT = 4).
DEFAULTVALUE
Set up to 10 default value(s) for the MetaProperty.
INITIALVALUE
Set up to 10 initial value(s) for the MetaProperty.
CATEGORY
If desired change the category of the MetaProperty to a value of the list. The property will then be moved to a new tab if the object is viewed in the View Test Environment or using the Object Editor.
NEEDSVALIDATION
Enable validation by checking the NEEDSVALIDATION attribute of the MetaProperty and let the system explicitely store a validation time stamp information in the database. This is particularly used on the mobile client in combination with the SYSCLS TASK and SYSCLS MEASUREMENTTASK classification.
 | 'NEEDSVALIDATION' is replaced by UBIK Attribute technique since Version 2.5! |

VALUEVALIDATION
Assign a value validation object to the VALUEVALIDATION attribute of the MetaProperty either by
