    copied!<p>I have problems with getting my JSP view right. What I intend to do is to send a List that contains questions and each question object is a text field and a List with alternatives.</p> <p>My intention is to be able to edit multiple questions (both to be able to edit the text/name of the question and edit the containing alternatives).</p> <p>My backing object is now sending an List question.</p> <p>Here is my JSP which are failing with invalid property of bean class.</p> <pre><code> &lt;form:form commandName="question"&gt; &lt;form:errors path="*"&gt; &lt;fieldset class="stdframe"&gt; &lt;legend&gt;Question&lt;/legend&gt; &lt;/fieldset&gt; &lt;/form:errors&gt; &lt;div class="stdframe"&gt; &lt;c:forEach var="q" items = "${question}" varStatus = "s"&gt; &lt;p&gt;&lt;b&gt;Question:&lt;/b&gt;&lt;/p&gt; &lt;p&gt;&lt;form:input size="67" path="${q.text}"/&gt;&lt;/p&gt; &lt;br/&gt; ${q.text} &lt;ul&gt; &lt;c:forEach var="alternative" items = "${q.alternatives}" varStatus = "t"&gt; ${alternative.text} &lt;li&gt;&lt;form:input path = "${alternative[$t.index].text}" /&gt;&lt;/li&gt; &lt;/c:forEach&gt; &lt;/ul&gt; &lt;br/&gt; &lt;/c:forEach&gt; &lt;input type="submit" class="submit" value="Save" /&gt; &lt;input type="button" class="button" onClick="back()" value="Back"/&gt; &lt;/div&gt; &lt;/form:form&gt; </code></pre> <p>I have tried both <code>${q.text}</code> and <code>${q[$s.index].text}</code>. When I just print <code>${q.text}</code> it shows the correct text for the question object. Same goes for alternative.</p> <p>What can I do to correctly bind the form to the objects?</p> <p>In addition when I store an object which contains a list of other object, will the list be stored itself in the database? </p>

An individual column

Larger individual text columns get their own page to allow for proper reading.
