Dynamic contraint loading query with searchService

[anita_platos]

I am trying to have a constraint loading its data through a searchService-query. The problem is that when I start the Alfresco, it keeps locked in the query, but it never starts.
This is the code I´m using:
- The java code for constraint:

package org.myproject.mycontraints;import java.util.ArrayList;import java.util.Collection;import java.util.Collections;import java.util.List;import org.alfresco.model.ContentModel;import org.alfresco.repo.dictionary.constraint.ListOfValuesConstraint;import org.alfresco.service.cmr.repository.NodeService;import org.alfresco.service.cmr.repository.StoreRef;import org.alfresco.service.cmr.search.ResultSet;import org.alfresco.service.cmr.search.ResultSetRow;import org.alfresco.service.cmr.search.SearchService; public class LoadingMyCombo extends ListOfValuesConstraint {    private static NodeService nodeService;    private static SearchService searchService;     @Override    public void initialize() {    }     @Override    public List<String> getAllowedValues() {        List<String> allowedValues = getSearchResult();        super.setAllowedValues(allowedValues);        return allowedValues;    }     private List<String> getSearchResult()     {        List<String> allowedValues = new ArrayList<String>();        String query ="PATH:\"/app:company_home/cm:DOCUMENTS\"";        ResultSet resultSet = searchService.query(StoreRef.STORE_REF_WORKSPACE_SPACESSTORE, SearchService.LANGUAGE_SOLR_FTS_ALFRESCO, query);        for (ResultSetRow row : resultSet)            allowedValues.add((String)nodeService.getProperty(row.getNodeRef(), ContentModel.PROP_NAME));         Collections.sort(allowedValues);         if (allowedValues.size() == 0)            allowedValues.add("");         return allowedValues;    }     @SuppressWarnings("unchecked")    @Override    public void setAllowedValues(List allowedValues) {    }     @Override    public void evaluateCollection(Collection<Object> collection) {    }     public void setNodeService(NodeService nodeService) {       LoadingMyCombo.nodeService = nodeService;    }     public void setSearchService(SearchService searchService) {       LoadingMyCombo.searchService = searchService;    }}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

- The constraint declared in the model:

   <constraint name="prfx:load-my-combo" type="org.myproject.mycontraints.LoadingMyCombo" >         <parameter name="allowedValues">               <list>               </list>         </parameter>         <parameter name="caseSensitive"><value>true</value></parameter>   </constraint>‍‍‍‍‍‍‍‍‍

- The bean to associate with the nodeService

   <bean id="mytests.myconstraints.ConstraintInitializer" class="org.myproject.mycontraints.LoadingMyCombo">       <property name="nodeService">         <ref bean="nodeService"/>      </property>      <property name="searchService">         <ref bean="searchService"/>      </property>   </bean>‍‍‍‍‍‍‍‍‍‍

Somebody knows if I´m doing something wrong or why it gets locked indefinitely  in the line where it executes the query?. I know that the query is well-done because I tested OK using the Node Browser console.
Thank you in advance

Hi Anita,
I had the same yours problem and I resolved him with your suggestions about counter!
Like you said this is not a very elegant solution.
Can you give me an example about the better solution with ftl control you were talking about?

Thank you very much!
