Having trouble creating new v8 style widget

Eric Borisow

Hi,

I am basically just trying to get the v8 sample widget extension to work and am having a bit of trouble.  First, I created a simple v7 widget:

MySampleWidget.java

import com.vignette.as.ui.cm.ctm.shared.widgets.VCMTextWidget;

public class MySampleWidget extends VCMTextWidget
{
   
}

 

Then, I just basically took the sample v8 widget classes:

SampleWidget.java

public class SampleWidget extends VUIAbstractWidget implements Serializable {
   
    private static Category log = Category.getInstance(SampleWidget.class);
   
    /** Number of rows. */
    private int rows;

    /** Number of columns. */
    private int cols;

    /** Maximum number of characters you can enter. */
    private int maxLength;

    /** Wrap options for the field */
    private String wrap;

  /*

  Other public getters and setters

  */

 

}

 

SampleWidgetMap.java

public class SampleWidgetMap extends VUIAbstractWidgetMap {
    /**
     * Attribute names found in existing widget.
     */

    /**
     * Number of rows.
     */
    private static final String ROWS = "rows";

    /**
     * Number of columns.
     */
    private static final String COLS = "cols";

    /**
     * Size in characters (password).
     */
    private static final String SIZE = "size";

    /**
     * Maximum number of characters you can enter.
     */
    private static final String MAX_LENGTH = "maxlength";

    /**
     * Wrapping options for the field
     */
    static final private String WRAP = "wrap";

}

 

Then, I have sample-widget-maps.xml:

sample-widget-maps.xml

<beans xmlns="http://www.springframework.org/schema/beans&quot;
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance&quot;
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans-2.5.xsd&quot;
       default-lazy-init="false">

    <bean name="MySampleWidget" class="vignette.customer.widget.SampleWidgetMap">
        <property name="widgetClass" value="vignette.customer.widget.SampleWidget"/>
    </bean>
</beans>

 

sample-widget-renders.xml

<beans xmlns="http://www.springframework.org/schema/beans&quot;
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance&quot;
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans-2.5.xsd&quot;
       default-lazy-init="false">

    <bean id="vignette.customer.widget.SampleWidget" class="vignette.customer.widget.SampleWidgetRenderer" scope="prototype">
        <property name="template" value="vcm-widget-text"/>

        <property name="templateResolver">
            <bean class="com.vignette.ui.vcm.widget.renderer.WidgetTemplateResolver"/>
        </property>
    </bean>
</beans>

 

The xml files are in the vignette.customer package.

 

I am able to deploy the widget jar and war.  When I pull up the widget in the CTD, I see my custom jsp getting rendered.  In the v8 editor, I don't receive the error about contacting the administrator, but it basically shows the simple Text widget.  But, I see no indication in any of the logs that my custom widget was used over a basic Text widget.  I wasn't entirely clear on how the system knows about render.jsp, but I have those in there from the sample too.  Here are the messages from the ui log:

Please point out what I'm doing wrong.

 

Thanks!

Ok, I'm a little farther along.  I just put in some simple System out prints and I see that the processStandardMapping method is getting called in my map class.  Here's a follow-up question.  How can I now control what is getting displayed on the page?  It seems that the render.jsp should be somehow involved, but how does it "know" to use it?  What will I need to do to make it use a certain jsp?

 

Thanks,

Eric
