请问问题如何处理啊

Answer 1

找不到元素，1、标签问题，2、标签中的属性，3、后台方法错误
这样试试：
<h:selectOneMenu id="applyTypes" styleClass="be_input" value="#{item.applyType}">
<f:selectItems value="#{CreateBeForm.typeSelectItemList}" />
<a4j:support event="onchange"action="#{CreateBeForm.applyTypeChanged}" reRender="currencyPanel">
<a4j:ajaxListener type="org.ajax4jsf.ajax.ForceRender" />
</a4j:support>
</h:selectOneMenu>

Answer 2

你在给属性设值的时候没能设置成功，，LZ可以Debug下，就清楚了。。
