Custom Constraint

В альфреске в Company Home/XML находится position.xml. Задача у меня следующая: на основе этого XML создавать динамический список, собственный constraint для использования в процессе.

Попробовала создать свой LIST, прочитав эту тему - http://www.ecm-alfresco.ru/viewtopic.php?f=14&t=54

 - Расширила класс ListOfValuesConstraint 

package my.constraints;

public class ListOfPositionsConstraint extends ListOfValuesConstraint implements Serializable {
 
	private static Log logger = LogFactory.getLog(BaseComponentGenerator.class);
 
	private static final long serialVersionUID=1;
 
	private FileFolderService fileFolderService;
	private SearchService searchService;
 
	private String POSITIONS_XML = "XML/positions.xml";
	private List<String> av = new ArrayList<String>();
 
	public void setFileFolderService(FileFolderService fileFolderService) {
		this.fileFolderService = fileFolderService;
	}
 
	public void setSearchService(SearchService searchService) {
		this.searchService = searchService;
	}
 
	private List<String> allowedLabels;
 
	public void setAllowedValues(List allowedValues) {}
 
	public void setCaseSensitive(boolean caseSensitive) {}
 
	public void initialize() {
		super.setCaseSensitive(true);
		this.loadData();
	}
 
	public List getAllowedValues() {
		this.loadData();
		return super.getAllowedValues(); 
	}
 
	public List<String> getAllowedLabels() {
		return this.allowedLabels;
	}
 
	public void setAllowedLabels(List<String> allowedLabels) {
		this.allowedLabels=allowedLabels;
	}
 
	public List<SelectItem> getSelectItemList() {
		List<SelectItem> result = new ArrayList<SelectItem>(this.getAllowedValues().size());
		for(int i=0;i<this.getAllowedValues().size();i++) {
			result.add(new SelectItem((Object)this.getAllowedValues().get(i),this.allowedLabels.get(i)));
		}
		return result;
	}
 
 
	protected NodeRef getNodeRef(NodeRef parent, String path) {
		...
	}

	public List parseXML(NodeRef xml) {
		...		
	}
 
	protected void loadData() {
		StoreRef storeRef = new StoreRef(StoreRef.PROTOCOL_WORKSPACE, "SpacesStore");
		ResultSet rs = searchService.query(storeRef, SearchService.LANGUAGE_XPATH, "/app:company_home");
		NodeRef companyHomeRef = null;
 
		List<String> av = new ArrayList<String>();
		List<String> al=new ArrayList<String>();
 
 
		try	{
			if (rs.length() == 0) logger.error("Cann't find Company Home");
			else companyHomeRef = rs.getNodeRef(0);
		} finally {
			rs.close();
		}
 
		if (companyHomeRef!=null) {
			NodeRef pNode = getNodeRef(companyHomeRef, POSITIONS_XML);
 
			if (pNode!=null) {
				av = parseXML(pNode);
				al = av;
			} else logger.error("Unable to locate "+POSITIONS_XML+" path");
		}
 
		super.setAllowedValues(av);
		this.setAllowedLabels(al);
 
	}
}

 - создала service-context.xml и поместила его в tomcat/shared/classes/alfresco/extension/: 

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'>
<beans>
 
	<bean id="ListOfPositionsConstraint" 
			class="my.constraints.ListOfPositionsConstraint" >
		<property name="searchService">
			<ref bean="searchService" />
		</property>
		<property name="fileFolderService">
			<ref bean="fileFolderService"/>
		</property>
	</bean>
 
</beans>

 - Добавила в модель следующее: 

...
 
 	<constraints>
		<constraint name="fappgu10:positionsLabel" type="myr.constraints.ListOfPositionsConstraint">
			<parameter name="allowedValues">
				<list>
				</list>
			</parameter>
			<parameter name="caseSensitive">
				<value>true</value>
			</parameter>
		</constraint>
	</constraints>
 
 ...
 
		<type name="fappgu10:performRequest">
			<parent>bpm:workflowTask</parent>
			<properties>
				<property name="fappgu10:positions">
					<type>d:text</type>

						<constraint ref="fappgu10:positionsLabel" />
					</constraints>
				</property>
			</properties>
			<overrides>
				<property name="bpm:packageActionGroup">
					<default>add_package_item_actions</default>
				</property>
				<property name="bpm:packageItemActionGroup">

				</property>
			</overrides>
			<mandatory-aspects>

				<aspect>fappgu10:pname</aspect>
				<aspect>fappgu10:address</aspect>
			</mandatory-aspects>
		</type>
 
...

 Альфреска падает при рестарте с сообщением о неудачной попытке задеплоить модель.

Что я делаю не так?

UPD: Заработало. Новый код:

package my.constraints;
 
public class ListOfPositionsConstraint extends ListOfValuesConstraint implements Serializable {
 
	org.alfresco.repo.jscript.ScriptLogger logger = new org.alfresco.repo.jscript.ScriptLogger();
 
	private static final long serialVersionUID=1;
 
 
	private String POSITIONS_XML = "XSL/positions.xml";
	private List<String> av = new ArrayList<String>();
 
	private static ServiceRegistry registry;
	private static Repository repository;
 
	public ServiceRegistry getServiceRegistry()	{
		return registry;
	}
 
	public void setServiceRegistry(ServiceRegistry registry)	{
		ListOfPositionsConstraint.registry = registry;
	}
 
	public void setRepository(Repository repository) {
		ListOfPositionsConstraint.repository = repository;
	}
 
	public Repository getRepository()	{
		return repository;
	}
 
	private List<String> allowedLabels;
 
	public void setAllowedValues(List allowedValues) {}
 
	public void setCaseSensitive(boolean caseSensitive) {}
 
	public void initialize() {
		super.setCaseSensitive(true);
		this.loadData();
	}
 
	public List getAllowedValues() {
		this.loadData();
		return super.getAllowedValues(); 
	}
 
	public List<String> getAllowedLabels() {
		return this.allowedLabels;
	}
 
	public void setAllowedLabels(List<String> allowedLabels) {
		this.allowedLabels=allowedLabels;
	}
 
	public List<SelectItem> getSelectItemList() {
		List<SelectItem> result = new ArrayList<SelectItem>(this.getAllowedValues().size());
		for(int i=0;i<this.getAllowedValues().size();i++) {
			result.add(new SelectItem((Object)this.getAllowedValues().get(i),this.allowedLabels.get(i)));
		}
		return result;
	}
 
	protected NodeRef getNodeRef(NodeRef parent, String path) {
...
	}
 
	public List parseXML(NodeRef xml) {
 ...
	}
 
	protected void loadData() {
		NodeRef companyHomeRef = null;
		try {
			companyHomeRef = getRepository().getCompanyHome();
		} catch(Exception ex){
			logger.error(ex.toString());
		}
		List<String> av = new ArrayList<String>();
		List<String> al=new ArrayList<String>();
		if (companyHomeRef!=null) {
			NodeRef pNode = getNodeRef(companyHomeRef, POSITIONS_XML);
 
			if (pNode!=null) {
				av = parseXML(pNode);
				al = av;
			} else logger.error("Unable to locate "+POSITIONS_XML+" path");
		}
 
		super.setAllowedValues(av);
		this.setAllowedLabels(al);
 
	}
}

service-context.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'>
<beans>
 
	<bean id="ListOfPositionsConstraint" 
			class="my.constraints.ListOfPositionsConstraint" >
 
		<property name="serviceRegistry">
			<ref bean="ServiceRegistry" />
		</property>
		<property name="repository">
			<ref bean="repositoryHelper" />
		</property>
	</bean>
 
</beans>

В модели изменений не было.
