How to use Struts <s:iterator> and <s:if> tags together?

I have lists of objects named allAlbums and allPhotos. Now, I want to show all photos in each album, so I used the following method.

My code is:

<s:iterator value="allAlbums">
  <s:iterator value="allPhotos">
    <s:if test="%{#allAlbums.albumid == #allPhotos.albumid}">
      <s:property value="photourl"/>
    </s:if>
  </s:iterator>                             
</s:iterator>

But, it is not working. Any suggestion what am I doing wrong?

Solution

  • Make sure that both of your object have appropriate getters/setters, then you can use feature provided by OGNL called projection.

    <s:iterator value="allAlbums" var="album">
  <s:iterator value="allPhotos.{? #this.albumid == #album.albumid}">
      <s:property value="photourl"/>
  </s:iterator>                             
</s:iterator>
