Life Cycle Constraints Example

The following example XML shows the out-of-the-box XML that sets the attribute display constraints for the life cycle template associated with a document.

The example is formatted to fit the page. Always enter each tag on one line:

<AttributeValues objType="wt.doc.WTDocument">
<AttrConstraint id="lifeCycle.id" algorithm=
"com.ptc.core.rule.server.impl.GatherAttributeConstraints">
<Value algorithm="com.ptc.core.rule.server.impl.GetServerAssignedConstraint"/>
<Value algorithm="com.ptc.core.rule.server.impl.GetImmutableConstraint"/>
</AttrConstraint>

<AttrConstraint id="lifeCycle" algorithm=
"com.ptc.core.rule.server.impl.GatherAttributeConstraints">
<Value algorithm="com.ptc.core.rule.server.impl.GetServerAssignedConstraint"/>
<Value algorithm="com.ptc.core.rule.server.impl.GetImmutableConstraint"/>
</AttrConstraint>
</AttributeValues>

The constraints are supplied for two attributes:

• lifeCycle.id (for fields from which users can search for a life cycle template)

• lifeCycle (for life cycle template fields that do not provide the search capability)

Using the constraints in the example, the New Document window includes the following:

From this interface, the life cycle template assigned is the one set by the server (in the AttrValue rule) and the user cannot change the template that is used.
