How to use screen widget type decorator for CMS

Vinay Agarwal
Hello,

I can't seem to make widget type decorator work with CMS (details below). I
tried changing decorator-section-include to decoratedContent but that didn't
work either (no body displayed). I would appreciate any guidance. Thanks in
advance.

Regards,
Vinay Agarwal

RE: How to use screen widget type decorator for CMS

David Garrett
In reply to this post by Vinay Agarwal
CMS content with SCREEN_COMBINED decorator

Does anyone know if I am wrong or does a CMS problem exist?

It seems it is not possible to create a content page with CMS which is
decorated by a SCREEN_COMBINED as opposed to the sample data which uses an
FTL decorator. To be more precise I *think* the problem arises when the
decorator has the following widget: <decorator-section-include name="body"/>

My guess is that the "body" is null from the textData at line 649 in
DataResourceWorker.java (I don't know why!)

org.ofbiz.widget.screen.ScreenRenderException: Error rendering screen
[component://ecommerce/widget/CommonScreens.xml#main-decorator]:
java.lang.NullPointerException (null)
org.ofbiz.widget.screen.ModelScreen.renderScreenString(ModelScreen.java:149)
org.ofbiz.content.data.DataResourceWorker.renderDataResourceAsText(DataResou
rceWorker.java:668)
org.ofbiz.content.content.ContentWorker.renderContentAsText(ContentWorker.ja
va:231)
org.ofbiz.content.content.ContentWorker.renderContentAsText(ContentWorker.ja
va:219)
org.ofbiz.content.cms.CmsEvents.cms(CmsEvents.java:214)
...

I have tried a variety of different simple decorators all with the
<decorator-section-include name="body"/>


The URL I used was ...
http://localhost:8080/cmssite/cms/CMSS_DEMO_PAGE_TST1


Here is the test data I tried...
<entity-engine-xml>

    <!-- screen decorator -->
    <DataResource dataResourceId="CMSS_MAIN_DEC_SCN"
dataResourceTypeId="URL_RESOURCE" dataTemplateTypeId="SCREEN_COMBINED"
 
objectInfo="component://ecommerce/widget/CommonScreens.xml#main-decorator"/>
    <Content contentId="CMSS_DEC_SCN" contentTypeId="DECORATOR"
contentName="CMS Site Main Decorator - Screen"
dataResourceId="CMSS_MAIN_DEC_SCN"/>
    <ContentPurpose contentId="CMSS_DEC_SCN"
contentPurposeTypeId="SECTION"/>
   
    <Content contentId="CMSS_DEMO_PAGE1_SCN" contentTypeId="DOCUMENT"
decoratorContentId="CMSS_DEC_SCN" contentName="CMS Site Demo Page 1 -
Screen" dataResourceId="CMSS_DEMO_PAGE1"/>
    <ContentPurpose contentId="CMSS_DEMO_PAGE1_SCN"
contentPurposeTypeId="SECTION"/>
    <ContentAssoc contentId="CMSS_PPOINT" contentIdTo="CMSS_DEMO_PAGE1_SCN"
contentAssocTypeId="SUB_CONTENT" fromDate="2001-01-01 00:00:00"/>
    <ContentAssoc contentId="CMSS_DEMO_PAGE1_SCN"
contentIdTo="CMSS_DEMO_PAGE1_1" contentAssocTypeId="SUB_CONTENT"
mapKey="sub1" fromDate="2001-01-01 00:00:00"/>
    <ContentAssoc contentId="CMSS_DEMO_PAGE1_SCN"
contentIdTo="CMSS_DEMO_PAGE1_2" contentAssocTypeId="SUB_CONTENT"
mapKey="sub2" fromDate="2001-01-01 00:00:00"/>

   
    <DataResource dataResourceId="CMSS_DEMO_PAGE_TST1"
dataResourceTypeId="ELECTRONIC_TEXT" dataTemplateTypeId="FTL" />
    <ElectronicText dataResourceId="CMSS_DEMO_PAGE_TST1">
        <textData><![CDATA[
            <div>Screen test content</div>
            ]]></textData>
    </ElectronicText>
    <Content contentId="CMSS_DEMO_PAGE_TST1" contentTypeId="DOCUMENT"
decoratorContentId="CMSS_DEC_SCN" contentName="CMS Site Demo Page Screen
TST1" dataResourceId="CMSS_DEMO_PAGE_TST1"/>
    <ContentPurpose contentId="CMSS_DEMO_PAGE_TST1"
contentPurposeTypeId="SECTION"/>
    <ContentAssoc contentId="CMSS_PPOINT" contentIdTo="CMSS_DEMO_PAGE_TST1"
contentAssocTypeId="SUB_CONTENT" fromDate="2001-01-01 00:00:00"/>

</entity-engine-xml>



I think Vinay's suggestion below was to use direct access to content like
the following blog example from BlogScreens.xml#CommonBlog ...
  <container style="blogtext">
     <sub-content map-key="SUMMARY" content-id="${blog.contentId}"/>
  </container>
This may work but it is quite inflexible.

Any suggestions as to what I should do to fix/resolve this issue.

Thanks
