    <p>I am using Drools and Liferay, and I am trying to insert in the BD a user when the rule was true, but Drools doesn't let me import a package. I don't have a .drl class, I pass a string to execute drools. This is my code:</p> <p>Code drools:</p> <pre><code>import com.liferay.portal.kernel.search.BooleanClause; import com.liferay.portal.kernel.search.BooleanClauseOccur; import com.liferay.portal.kernel.search.BooleanClauseFactoryUtil; import com.liferay.portal.kernel.search.BooleanQuery; import com.liferay.portal.kernel.search.BooleanQueryFactoryUtil; import com.liferay.portal.kernel.search.Document; import com.liferay.portal.kernel.search.Field; import com.liferay.portal.kernel.search.Hits; import com.liferay.portal.kernel.search.Indexer; import com.liferay.portal.kernel.search.IndexerRegistryUtil; import com.liferay.portal.kernel.search.SearchContext; import com.liferay.portal.kernel.util.GetterUtil; import com.liferay.portal.kernel.util.KeyValuePair; import com.liferay.portal.kernel.util.StringUtil; import com.liferay.portal.kernel.util.Validator; import com.liferay.portal.model.Address; import com.liferay.portal.model.Group; import com.liferay.portal.model.Contact; import com.liferay.portal.model.User; import com.liferay.portal.service.AddressLocalServiceUtil; import com.liferay.portal.util.PortalUtil; import com.liferay.portlet.asset.model.AssetEntry; import com.liferay.portlet.asset.service.AssetEntryLocalServiceUtil; import com.liferay.portal.model.User; import com.liferay.portal.security.auth.PrincipalThreadLocal; import com.liferay.portal.security.permission.PermissionChecker; import com.liferay.portal.security.permission.PermissionCheckerFactoryUtil; import com.liferay.portal.security.permission.PermissionThreadLocal; import com.liferay.portal.kernel.util.ObjectValuePair; import com.liferay.portlet.expando.model.ExpandoBridge; import java.io.Serializable; import java.util.ArrayList; import java.util.Collections; import java.util.HashMap; import java.util.Iterator; import java.util.List; import java.util.Map; import com.segmentationPortlet.controller.prova; rule "Initialize Rules" salience 1000 when user : User(); then end rule "Rule_1" when userRule_2: User(emailAddress == "test@liferay.com") user: User(); then prova p; p.classification(user,"SegmentUser"); end </code></pre> <p>Code to execute Drools; //rule is a string that have Drools's code.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
