a4j:htmlCommandLink dynamic id not working

[stefanorg]

Hi all,

i want to set the id on a link in a dataTable, because i want to set up a test and i need it.

i've a rich:dataTable, the first column is a link to edit the element :

<rich:column>
    <f:facet name="header">
         <h:outputText value="Username" />
    </f:facet>
    <a4j:htmlCommandLink id="_#{item.username}_editLink" action="editUser">
         <f:setPropertyActionListener value="#{item.id}" target="#{utentiBean.id}"/>
        <h:outputText value="#{item.username}"/>
    </a4j:htmlCommandLink>
</rich:column>

#{item.username} is not null because i can see it rendered in the table <h:outputText value="#{item.username}"/> but the link id is not correct, it is in this form:

id="j_id70:superList_tbl:1:__editLink"

Thanks for any help

Hi,

How does 'item' is defined on the page?

[stefanorg]

Hi Nick,

'item' is the var attribute of a rich:dataTable, i've my own component that wraps a rich:dataTable:

<link:dataTable id="superList"

                                                            value="#{utentiDM}"

                                                            headerText="Lista Utenti"

                                                            showSelectAll="true"

                                                            selectionMapTarget="#{utentiBean.selectedIds[item]}"

                                                            mBean="#{utentiBean}">

                                                            <rich:column>

                                                                      <f:facet name="header">

                                                                                <h:outputText value="Username" />

                                                                      </f:facet>

                                                                      <a4j:htmlCommandLink action="editUser">

                                                                                <f:setPropertyActionListener value="#{item.id}" target="#{utentiBean.id}"/>

                                                                                <h:outputText value="#{item.username}"/>

                                                                      </a4j:htmlCommandLink>

                                                            </rich:column>

                                                            <rich:column>

                                                                      <f:facet name="header">

                                                                                <h:outputText value="Soggetti Associati" />

                                                                      </f:facet>

                                                                      <a4j:htmlCommandLink action="editUser">

                                    <f:setPropertyActionListener value="#{item.id}" target="#{utentiBean.id}"/>

                                    <h:outputText id="sizeSoggetti" value="Visualizza (#{item.sizeSoggetti})" rendered="#{item.sizeSoggetti>0}" />

                                    <rich:toolTip value="#{item.nomiSoggettiAssociati}" for="sizeSoggetti" rendered="#{item.sizeSoggetti>0}"/>

                            </a4j:htmlCommandLink>

                                                            </rich:column>

                                                            <ui:define name="buttons">

                                                                      <h:commandButton styleClass="icon-add" value="Aggiungi Nuovo" action="editUser"/>

                                                            </ui:define>

                                                  </link:dataTable>

where link:dataTable inside is:

<rich:dataTable 

                                        value="#{value}"

                                        var="item"

                                        rows="#{rowsToDisplay}"

                                        id="#{id}_tbl"

                                        onRowMouseOver="activeRow(this)"

                                        rowClasses="even,odd"

                                        width="#{width}">

....

It doesn't work that way - component tree is built and id is assigned *before* collection is iterated over.

[stefanorg]

so it's not possible to use a value from the collection to build the id? If you would like to create an id depending on some value of your collection, there is a way to do that?

Generally no, check this article that describes the related problem: http://www.ilikespam.com/blog/c:foreach-vs-ui:repeat-in-facelets
