JSF - 从ArrayList中浏览和打印值 <String[]> 使用EL

Question

I have an ArrayList from a Bean :

...
public ArrayList<String[]> getArticleList() {
    ...
}
...

I need to print these values (with getter method) by using EL on JSF2 (such as #{bean.articlesLage}

How can I do this? Cheers

Answer 1

I don't remember if JSF supports arrays, however if you can convert your ArrayList<Array> to ArrayList<ArrayList<String>> , then something like this should work

<ui:repeat value="#{bean.articleList}" var="t">
   <ui:repeat value="#{t}" var="s">
      #{s}
   </ui:repeat>
</ui:repeat>

Answer 2

You can use a nested ui:repeat or a nested datatable like this with your current model ArrayList :

<h:dataTable value="#{bean.articleList}" var="row">
    <h:column>
        <f:facet name="header">
            <h:outputText value="COL" />
        </f:facet>
        <h:dataTable value="#{row}" var="nested_row">
            <h:column>
            <f:facet name="header">
                <h:outputText value="COL" />
            </f:facet>
                <h:outputText value="#{nested_row}" />
            </h:column>
    </h:dataTable>          
    </h:column>
</h:dataTable>
