                                <rich:treeNode>

                                    <h:commandLink value="#{one.item1}"
                                        action="#{Bean.getItem()}"
                                        style="color:blue;text-decoration:none;"
                                        title="Click here to view details">
                                        <f:param name="ids" value="#{one.id}">          
                                        </f:param>
                                    </h:commandLink>


                                    <a4j:support event="onclick" reRender="productInformation"

                                                                        action="#{Bean.getItem()}"/>
                               </rich:treeNode>

Solved the solution by using a4j:commandlink tag and passing the parameter from a function.
< a4j:commandLink ajaxSingle="true" value="#{item.Description}(#{item.name})"
action="#{Bean.getProductLink(item.paramID)}" style="color:blue;text-decoration:none;" title="#{item.productDescription}" reRender="addproductGuidForms"/>

is working fine.

Since you are using JSF2 there is no need to pass with f:param just pass it in method args 

action="#{Bean.getItem(one.id)}"

b.t.w you better rename the method name into action="#{Bean.retrieveItem(one.id)}"
