Ordering List, getting: value="#{row.value}": Property 'valu

[mtaal]

Hi,
I am trying the new orderinglist component but I having trouble when I submit the page with the ordering list (when there is at least one entry in the list). Here is the error message I get (see below for the longer stacktrace):
Caused by javax.servlet.ServletException with message: "/pages/product/ProductEdit.xhtml @270,76 value="#{row.value}": Property 'value' not found on type java.lang.String"

When I render it once with an entry in the list then it works fine, when this page (with the one entry in the list) is submitted then I get this message.

and here is my orderinglist:

<rich:orderingList
 id="productInternationalDescriptionList" var="row"
 value="#{entityHome.getWrappedCollection('internationalDescription')}"
 styleClass="inline-data-table"
 onRowMouseOver="previousStyleClassName = this.className; this.className='row-hover'"
 onRowMouseOut="this.className = previousStyleClassName"
 columnClasses="column-left max-width small-cell, column-left small-cell" width="100%"
 rowClasses="row-odd, row-even">
 <rich:column>
 <h:outputText value="#{row.value}" converter="#{entityOutputConverter}"/>
 </rich:column>
 <rich:column>
 <a4j:commandButton type="image" action="#{row.removeFromCollection}"
 limitToList="true"
 ajaxSingle="true" reRender="productInternationalDescriptionListPanel"
 image="/gfx/trashcan.gif"
 focus="productInternationalDescription"
 title="#{messages.removeFromList}"/>
 </rich:column>
 </rich:orderingList>

am I doing something wrong?

Thanks!

gr. Martin

you should use converter for your objects to use orderingList.

[mtaal]

Hmm, I do not completely understand, this column definition worked fine with datatable.

Also when I look at the orderinglist in the rich faces demo I do not see a converter:

 <rich:orderingList value="#{library.libraryAsList}" var="lib" listHeight="300" listWidth="350">

 <rich:column width="180">

 <f:facet name="header">

 Song Name

 </f:facet>

 <h:outputText value="#{lib.title}"></h:outputText>

 </rich:column>

 <rich:column>

 <f:facet name="header">

 Artist Name

 </f:facet>

 <h:outputText value="#{lib.album.artist.name}"></h:outputText>

 </rich:column>

 </rich:orderingList>

I am not sure of the intended use of the orderingList. I want to use it to order items in a list. The changed list should then be put back in the correct property of the backing bean.
The list in this case is a value in a bean property.

With this in mind I do not really understand how I should use the selection property?

Thanks!

you shouldn't use a converter only if OL value is simple Strings list.

demosite has no converter because in the sample there is no submission and OL never need to store its value. :)

[tjdecke]

Is it possible to use the ordering List as a "mini-multi-select Datatable" ?
Can i somehow get rid of the value submission? I'd like to use it as a multi-select Data table.

What would be the easiest way to remove the necessity of a converter for this component and just have it submit the selection only?

Thanks in Advance.

Hello,

Looks like the easiest way will be to write your own component using scripts from OL.
