could hierarchy fit combination of list / map data structures? have hierarchal data i'm working on showing in jsp, 3 or levels deep. map has key-value set of lists, list has other lists, etc. here of jsp code. uses expression langauge , jstl tags keep things simpler:
<section id="content" class="body"> <ol id="posts-list" class="hfeed"> <c:foreach items="${learningentries}" var="learningentry"> <li> <table class="wisientry"> <tr> <td class="picturecell"> <img class="wisientry-pic" src="${learningentry.imagepath}" /> <div class="tags"> <c:foreach items="${learningentry.tags}" var="tag"> <a class="tag" href="/tags/${tag.name}">${tag.name}</a> </c:foreach> </div> </td> <td class="previousnextcell" <div class="wisientry-nextsamplebutton">next</div> <div class="wisientry-previoussamplebutton">previous</div> <br /> <div class="wisientry-addtagbutton">tag</div> <div class="wisientry-addcommentbutton">comment</div> <br /> <div class="wisientry-uploadbutton">upload</div> </td> <td> <!-- error happens here. samples should not null --> <c:foreach items="${learningentry.samples}" var="sample" varstatus = "status"> <table class="sampleentry" ${status.first ? '' : 'style = "display:none"'}> <tr> <td class="samplecell"> <p class="description"> ${sample.description} </p> ...
