  1. POValues in rich:dataTable not getting updated in the bean
    text
    copied!<p>This problem is when we are migrating to richfaces4.3 and JSF2.0. </p> <p>The context is: A rich:dataTable takes answerId, answerDefinition etc in their respective columns. An onchange event is executed on the answerid column, wherein a new row is added. </p> <pre><code>&lt;rich:extendedDataTable rowKeyVar="currentRowVar" value="#{DiscQuestMgtController.answerChoiceList}" var="dataItem" rowClasses="row1, row2" id="ansChoiceList"&gt; &lt;rich:column width="160" sortable="false"&gt; &lt;h:inputText id="answerID" value="#{dataItem.answerId}" onchange="addNewRowToAnsChoice('DiscQuestMgtForm',#{fn:length(DiscQuestMgtController.answerChoiceList)});" /&gt; &lt;/rich:column&gt; &lt;rich:column sortable="false"&gt; &lt;h:inputText id="choiceValue" value="#{dataItem.choiceValue}"/&gt; &lt;/rich:column&gt; &lt;rich:column sortable="false"&gt; &lt;h:inputText id="definitionId" value="#{dataItem.definition}"/&gt; &lt;/rich:column&gt; &lt;/rich:extendedDataTable&gt; </code></pre> <p>When retrieving the values into the dataTable, the working is fine. But when I enter the value into answerId(the first cell) and shift focus, the existing row is totally eliminated creating a new row. </p> <p><strong>addNewRowToAnsChoice</strong> , JS method, does few validations of the entered values and in turn calls a a4j function .. <strong>addEmptyAnsChoice</strong> .. The below is the code, that adds a new row, in the backing bean. </p> <p>//AddNewRow</p> <pre><code>public void addEmptyRow( ActionEvent ae ) { removeEmptyChoiceRow(); String logStr = " DiscQuestMgtController:addEmptyRow()&gt;&gt;&gt;"; logger.debug( logStr + " Entered" ); AnswerChoiceBean bean = new AnswerChoiceBean(); bean.setQuestionId( discQuestBean.getQuestionId() ); logger.debug( logStr + "Choice list size: answerChoiceList size--&gt;",answerChoiceList.size() ); //@abc if ( answerChoiceList.size() == 1 ) answerChoiceList.get( 0 ).setQuestionId( discQuestBean.getQuestionId() ); if ( !answerChoiceList.contains( bean ) ) answerChoiceList.add( bean ); logger.debug( logStr + " Returned" ); } </code></pre> <p>removeEmptyChoiceRow() checks if there are any existing empty rows and deletes them, to add a new row. @abc, the list size is always the default one. (there is always one row on page load), which is just not changing though the values are entered. Pls suggest!!</p> <p>This is the a4j:function:</p> <pre><code>&lt;a4j:jsFunction name="addEmptyAnsChoice" render="ansChoiceList,addDiscQuest,applyDiscQuest" actionListener="#{DiscQuestMgtController.addEmptyRow}" oncomplete="focusToNewCell('DiscQuestMgtForm',#{fn:length(DiscQuestMgtController.answerChoiceList)});"&gt; &lt;/a4j:jsFunction&gt; </code></pre>
