Hi Luar,
Hava a look on UI Validation @customization guide. Lot of OOTB Java validator class is responsible for hiding/enabling/disabling an action. Explore it.
Creating a Validator
Creating a validator class should be fairly simple. All you need to do is create a
class that extends com.ptc.core.ui.validation.DefaultUIComponentValidator.
The class below represents a skeleton for a simple validator class.
package com.ptc.windchill.enterprise.myPackage.validators;
import com.ptc.core.ui.validation.DefaultUIComponentValidator;
public class MyValidator extends DefaultUIComponentValidator{
//override one or more validation methods from
DefaultUIComponentValidator
}
Implementing Pre-Validation Methods
Once you’ve created a validator class skeleton, if you’re adding pre-validation
logic for an attribute, you’ll want to implement the performLimitedPreValidation()
method. If you’re adding pre-validation logic for an action, you’ll want to
implement both the performFullPreValidation() and performLimitedPreValidation()
methods. As mentioned in the previous sections regarding limited pre-validation
and full pre-validation, the implementations of these two methods may be
identical, or they may differ. The class on the next page contains some skeleton
implementations of these methods.
public class MyValidator extends DefaultUIComponentValidator{
@Override
public UIValidationResultSet performFullPreValidation()
(UIValidationKey validationKey,
UIValidationCriteria validationCriteria, Locale
locale) throws WTException {
UIValidationResultSet resultSet =
UIValidationResult.newInstance();
// perform your business logic here
// if you want to enable the action/component, do this:
//
resultSet.addResult(UIValidationResult.newInstance(validationKey,
// UIValidationStatus.ENABLED));
// if you want to disable the action/component, do this:
//
resultSet.addResult(UIValidationResult.newInstance(validationKey,
// UIValidationStatus.DISABLED));
// if you want to hide the action/component, do this:
//
resultSet.addResult(UIValidationResult.newInstance(validationKey,
UIValidationStatus.HIDDEN));
return resultSet;
}
@Override
public UIValidationResultSet performLimitedPreValidation()
(UIValidationKey validationKey,
UIValidationCriteria validationCriteria, Locale
locale) throws WTException {
UIValidationResultSet resultSet =
UIValidationResultSet.newInstance();
// perform your business logic here
// if you want to enable the action/component, do this:
//
resultSet.addResult(UIValidationResult.newInstance(validationKey,
// UIValidationStatus.ENABLED));
// if you want to disable the action/component, do this:
//
resultSet.addResult(UIValidationResult.newInstance(validationKey,
// UIValidationStatus.DISABLED));
// if you want to hide the action/component, do this:
//
resultSet.addResult(UIValidationResult.newInstance(validationKey,
UIValidationStatus.HIDDEN));
return resultSet;
}
}
Basic Validator Registration
To register your validator (using only the action name for an action), you need to
add an entry to *service.properties.xconf like this:
<Service context="default"
name="com.ptc.core.ui.validation.UIComponentValidator">
<Option requestor="null" serviceClass="[your fully-qualified
Validator class]"
selector="[action name/attribute descriptor ID]" />
</Service>
Once propagated to *service.properties, it should produce an entry like this:
wt.services/svc/default/com.ptc.core.ui.vali
dation.UIComponentValidator/[action name/attribute descriptor ID]/null/0=[your fullyqualified
Validator class]/duplicate
• Note that in this case, the requestor attribute is null, meaning the action’s object
type is not used in the lookup.
