    <p>I migrated some of my facelets custom components into proper composite components, but encounters the following error while rendering a view that contains the composite component:</p> <pre><code>javax.faces.view.facelets.TagException: /WEB-INF/taglib/cctest.xhtml @15,26 &lt;composite:interface&gt; Component Not Found for identifier: bodyId.getParent(). at com.sun.faces.facelets.tag.composite.InterfaceHandler.validateComponent(InterfaceHandler.java:135) at com.sun.faces.facelets.tag.composite.InterfaceHandler.apply(InterfaceHandler.java:125) at javax.faces.view.facelets.CompositeFaceletHandler.apply(CompositeFaceletHandler.java:95) at com.sun.faces.facelets.compiler.NamespaceHandler.apply(NamespaceHandler.java:93) at com.sun.faces.facelets.compiler.EncodingHandler.apply(EncodingHandler.java:87) at com.sun.faces.facelets.impl.DefaultFacelet.include(DefaultFacelet.java:320) at com.sun.faces.facelets.impl.DefaultFacelet.include(DefaultFacelet.java:379) at com.sun.faces.facelets.impl.DefaultFaceletContext.includeFacelet(DefaultFaceletContext.java:326) at com.sun.faces.facelets.tag.UserTagHandler.apply(UserTagHandler.java:142) at javax.faces.view.facelets.DelegatingMetaTagHandler.applyNextHandler(DelegatingMetaTagHandler.java:137) at com.sun.faces.facelets.tag.jsf.ComponentTagHandlerDelegateImpl.apply(ComponentTagHandlerDelegateImpl.java:187) at javax.faces.view.facelets.DelegatingMetaTagHandler.apply(DelegatingMetaTagHandler.java:120) at javax.faces.view.facelets.CompositeFaceletHandler.apply(CompositeFaceletHandler.java:95) at com.sun.faces.facelets.tag.jsf.core.ViewHandler.apply(ViewHandler.java:188) at javax.faces.view.facelets.CompositeFaceletHandler.apply(CompositeFaceletHandler.java:95) at com.sun.faces.facelets.compiler.NamespaceHandler.apply(NamespaceHandler.java:93) at com.sun.faces.facelets.compiler.EncodingHandler.apply(EncodingHandler.java:87) at com.sun.faces.facelets.impl.DefaultFacelet.apply(DefaultFacelet.java:164) at com.sun.faces.application.view.FaceletViewHandlingStrategy.buildView(FaceletViewHandlingStrategy.java:906) at com.sun.faces.lifecycle.RenderResponsePhase.execute(RenderResponsePhase.jav </code></pre> <p>In the error message, the name <code>bodyId</code> refers to the id of <code>&lt;h:body&gt;</code> in the file below, and <code>getParent()</code> is hardcoded during the creation of the exception message. <code>@15,26</code> refers to the end of <code>&lt;composite:interface&gt;</code> in cctest.xhtml below.</p> <p>Here is the page that contains the composite component:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:f="http://java.sun.com/jsf/core" xmlns:bam="http://bam.mycompany.com/jsftaglib" &gt; &lt;f:view locale="en" id="viewId"&gt; &lt;h:head id="headId"&gt; &lt;meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/&gt; &lt;title&gt;Title&lt;/title&gt; &lt;/h:head&gt; &lt;h:body id="bodyId"&gt; &lt;bam:cctest value="hello world."/&gt; &lt;/h:body&gt; &lt;/f:view&gt; &lt;/html&gt; </code></pre> <p>Here is the file named <code>cctest.xhtml</code> that declares the composite component <code>cctest</code>:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml" xmlns:composite="http://java.sun.com/jsf/composite" xmlns:h="http://java.sun.com/jsf/html" &gt; &lt;h:head&gt; &lt;title&gt;not used&lt;/title&gt; &lt;/h:head&gt; &lt;h:body&gt; &lt;composite:interface&gt; &lt;composite:attribute name="value" required="true"/&gt; &lt;/composite:interface&gt; &lt;composite:implementation&gt; &lt;h:outputText id="text_#{cc.attrs.value}" value="#{cc.attrs.value}"/&gt; &lt;/composite:implementation&gt; &lt;/h:body&gt; &lt;/html&gt; </code></pre> <p>The composite component is declared in a file named bam.taglib.xml located in /WEB-INF/taglib/, next to <code>cctext.xhtml</code>.

My faces-config.xml file is empty, there's no managed beans or other custom-defined components (validator, etc.). Web.xml only declares a few context param, plus the faces servlet mapped on *.xhtml; here are those context parameters:</p> <ul> <li>javax.faces.FACELETS_REFRESH_PERIOD = 1</li> <li>javax.faces.FACELETS_SKIP_COMMENTS = false</li> <li>javax.faces.FACELETS_LIBRARIES = /WEB-INF/taglib/bam.taglib.xml</li> <li>javax.faces.PROJECT_STAGE = Development</li> <li>javax.faces.VALIDATE_EMPTY_FIELDS = false</li> <li>javax.faces.INTERPRET_EMPTY_STRING_SUBMITTED_VALUES_AS_NULL = true</li> </ul> <p>Looking at the component tree that is displayed in the facelets error page, there's no element named <code>bodyId</code>, which might be a hint for my issue. A copy of which is displayed below:</p> <pre><code>&lt;UIViewRoot id="j_id1" inView="true" locale="en" renderKitId="HTML_BASIC" rendered="true" transient="false" viewId="/pages/composite_component_test.xhtml"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt; &lt;UIOutput id="headId" inView="true" rendered="true" transient="false"&gt; &lt;meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/&gt; &lt;title&gt;Title&lt;/title&gt; &lt;/UIOutput&gt; &lt;/UIViewRoot&gt; </code></pre> <p>Many thanks in advance for looking at this issue.</p>

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.

SQuiL has stopped working due to an internal error.

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