    copied!<p>I faced with problem, when I put value as <code>String</code> into <code>List&lt;String&gt;</code> inside <code>&lt;ui:repeat&gt;</code> when I press button I see that <code>List&lt;String&gt;</code> contains just records for last element of ui:repeat.</p> <pre><code>&lt;ui:repeat value="#{util:toList(test.mapQestionsWithAnswers)}" var="entry"&gt; &lt;h:inputHidden value="#{entry.key.questionId}" /&gt; &lt;h:outputText value="#{entry.key.question}" rendered="#{not empty entry.value}" /&gt; &lt;p:selectManyCheckbox value="#{test.questionAnswerList}" layout="pageDirection"&gt; &lt;f:selectItems value="#{entry.value}" var="ans" itemValue="#{entry.key.questionId} #{ans.answer.answerId}" itemLabel="${ans.answer.answer}" /&gt; &lt;/p:selectManyCheckbox&gt; &lt;/ui:repeat&gt; </code></pre> <p>Idea with <code>util:toList</code> from Baluscanswer <a href="https://stackoverflow.com/questions/6001743/how-to-show-hashmap-values-in-jsf">How to show hashmap values in jsf?</a></p> <p><strong>//UPDATED</strong> I rewrite this code without using map</p> <pre><code>&lt;ui:repeat value="${test.questionList}" var="question"&gt; &lt;h:outputText value="#{question.question}" rendered="#{not empty question}" /&gt; &lt;p:selectManyCheckbox value="#{test.questionAnswerList}" layout="pageDirection"&gt; &lt;f:selectItems value="#{question.questionAnswers}" var="ans" itemValue="#{ans.questionAnswerIdentifer.questionId} #{ans.questionAnswerIdentifer.answerId}" itemLabel="#{ans.answer.answer}" /&gt; &lt;/p:selectManyCheckbox&gt; &lt;/ui:repeat&gt; </code></pre> <p>But it doesn't help me I can get in <code>List&lt;String&gt;</code> just pairs question answer for last question in <code>&lt;ui:repeat/&gt;</code>. Seems as after every iteration questionAnswerList become empty</p> <p>//Ok I read some article <a href="https://stackoverflow.com/questions/13147440/primefaces-manycheckbox-inside-uirepeat-calls-setter-method-only-for-last-loop">Primefaces ManyCheckbox inside ui:repeat calls setter method only for last loop</a></p> <p>And I decide use map Map></p> <p>But in this part error <code>ClassCastException</code> String cannot be cast to List</p> <pre><code>public List&lt;String&gt; getQuestionAnswerList() { // return questionAnswerList; List&lt;String&gt; selectedQuestionAnswer = new ArrayList&lt;String&gt;(); if (!selectedItems.isEmpty()) { Set&lt;Long&gt; idsSet = selectedItems.keySet(); for(Long questionId : idsSet){ List&lt;String&gt; questionAnswerPair = selectedItems.get(questionId); selectedQuestionAnswer.addAll(questionAnswerPair); } } return selectedQuestionAnswer; } &lt;p:selectManyCheckbox value="#{test.selectedItems[question.questionId]}" layout="pageDirection"&gt; &lt;f:selectItems value="#{question.questionAnswers}" var="ans" itemValue="#{ans.questionAnswerIdentifer.questionId} #{ans.questionAnswerIdentifer.answerId}" itemLabel="#{ans.answer.answer}" /&gt; &lt;/p:selectManyCheckbox&gt; </code></pre> <p>How I can get all choosen values in <code>List&lt;String&gt;</code>?</p>
