Creating a rich:tree with adaptor on single root node

[tomba]

Hi all,

we're converting from JSF1.2 to JSF2+RF4, but we've hit a bit of a bump with trees.

With RF4, we've tested a few scenarios, and here is what works:

                    <rich:tree toggleType="client" var="item">
                        <rich:treeModelRecursiveAdaptor roots="#{quoteOptions.packs}" nodes="#{item.subOptionNodes}" >
                            <rich:treeNode>#{item}</rich:treeNode>
                            <rich:treeModelAdaptor nodes="#{item.subOptionNodes}">
                                <rich:treeNode>#{item}</rich:treeNode>
                            </rich:treeModelAdaptor>
                        </rich:treeModelRecursiveAdaptor>
                    </rich:tree>

This gives me one single tree.

However, I want seperate trees for the root nodes, so I thought to do this (similar to what we did in JSF1.2:

<h:dataTable cellpadding="0" cellspacing="0" width="98%"  value="#{quoteOptions.packs}" var="pack" styleClass="sortable">
<h:column>
                    <rich:tree toggleType="client" var="item" >
                        <rich:treeModelRecursiveAdaptor roots="#{pack}" nodes="#{item.subOptionNodes}" >
                            <rich:treeNode>#{item}</rich:treeNode>
                            <rich:treeModelAdaptor nodes="#{item.subOptionNodes}">
                                <rich:treeNode>#{item}</rich:treeNode>
                            </rich:treeModelAdaptor>
                        </rich:treeModelRecursiveAdaptor>
                    </rich:tree>
</h:column>
</h:dataTable>

Unfortunately this doesn't render anything.

I read in the docs that the "roots" attribute on treeModelRecursiveAdapter needs a list of root nodes, but obviously I have just one.

Is this the reason why the tree isn't built?

How can we work around this problem?

Thanks

Steven

unfortunatelly seems the only immediate solution will be to return some list with the single value.

Thanks Ilya for registering the issue.

It would be great if the component can check if the roots attrib is a list, and if not use the value as the root itself.

I think such a fix would be simple and will ease conversion from RF3 to RF4.

Also note that the component documentation is talking about the "root" attribute, which obviously should be "roots"

it was like there in 3.3.x and will be again after the fix so thanks for your report.. will be helpfull to other who will migrate in future
