Cryptic 'Unable to find setter method for attribute&quo

[steel]

I have created a new HasAspectEvaluator custom tag.

<tag>
        <name>hasAspectEvaluator</name>
        <tag-class>com.tsgrp.alfresco.web.ui.common.tag.evaluator.HasAspectEvaluatorTag</tag-class>
        <body-content>JSP</body-content>

        <attribute>
            <name>id</name>
            <required>false</required>
            <rtexprvalue>true</rtexprvalue>
        </attribute>

        <attribute>
            <name>value</name>
            <required>true</required>
            <rtexprvalue>true</rtexprvalue>
        </attribute>

        <attribute>
            <name>binding</name>
            <required>false</required>
            <rtexprvalue>true</rtexprvalue>
        </attribute>

        <attribute>
            <name>condition</name>
            <required>true</required>
            <rtexprvalue>true</rtexprvalue>
        </attribute>
    </tag>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I have the setters correctly set.

public class HasAspectEvaluator extends BaseEvaluator
{
     /**
     * the string condition to match value against
     */
    private String condition = null;

    /**
     * Evaluate against the component attributes. Return true to allow the inner
     * components to render, false to hide them during rendering.
     *
     * @return true to allow rendering of child components, false otherwise
     */
    public boolean evaluate()
    {
        FacesContext context = FacesContext.getCurrentInstance();
        NodeService nodeService = Repository.getServiceRegistry(context).getNodeService();

        boolean result = false;

        try
        {
            result = nodeService.hasAspect((NodeRef)getValue(), Repository.resolveToQName(getCondition()));
        }
        catch (Exception err)
        {
            // return default value on error
            s_logger.debug("HasAspectEvaluator error : " + getValue());
        }

        return result;
    }

    /**
     * @see javax.faces.component.StateHolder#restoreState(javax.faces.context.FacesContext, java.lang.Object)
     */
    public void restoreState(FacesContext context, Object state)
    {
        Object values[] = (Object[]) state;
        // standard component attributes are restored by the super class
        super.restoreState(context, values[0]);
        this.condition = (String) values[1];
    }

    /**
     * @see javax.faces.component.StateHolder#saveState(javax.faces.context.FacesContext)
     */
    public Object saveState(FacesContext context)
    {
        Object values[] = new Object[2];
        // standard component attributes are saved by the super class
        values[0] = super.saveState(context);
        values[1] = this.condition;
        return (values);
    }

    public String getCondition()
    {
        ValueBinding vb = getValueBinding("condition");
        if (vb != null)
        {
            this.condition = (String) vb.getValue(getFacesContext());
        }

        return this.condition;
    }

    public void setCondition(String condition)
    {
        this.condition = condition;
    }
}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I also have the component correctly defined in the xml. Yet when I try to load the JSP page:

17:04:39,536 ERROR [[localhost].[/connectsite].[jsp]] Servlet.service() for servlet jsp threw exception
org.apache.jasper.JasperException: /jsp/browse/browse.jsp(675,4) Unable to find setter method for attribute: condition
   at org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:39)

   at org.apache.jasper.compiler.Generator$GenerateVisitor.visit(Generator.java:1685)‍‍‍‍‍‍‍‍‍

Here's the JSP code:

<t:hasAspectEvaluator value="#{r}" condition="tsg:faxDoc">
        <r:permissionEvaluator value="#{r}" allow="ChangePermissions">
            <a:actionLink value="#{msg.manage_content_users}" image="/images/icons/invite.gif"
                          action="dialog:manageContentUsers" actionListener="#{BrowseBean.setupContentAction}">
                <f:param name="id" value="#{r.id}"/>
            </a:actionLink>
        </r:permissionEvaluator>
    </t:hasAspectEvaluator>‍‍‍‍‍‍‍‍

I am really stumped on this. I have tried re-compiling, re-deploying, re-starting my IDE, tried Tomcat 5.5.15 & 5.5.16. All produce the same errors. I have gone over my code over and over again.

Any ideas?

thanks.

Can you show the code for your HasAspectEvaluatorTag class? As this is the class that the "unable to find…" error is related too - there should be a setter method for "condition" in that class i.e. setCondition(String s)

Thanks,

Kevin

Hi,

The error is coming from the tag class not the evaluator implementation that you have listed.

Basically, setCondition() is missing from com.tsgrp.alfresco.web.ui.common.tag.evaluator.HasAspectEvaluatorTag.

Yes that was the problem.  Thanks a lot for the help!
