【问题描述】:
我正在处理带有字段验证的 JSF 表单。
<h:form>
<h:panelGrid id="panel" styleClass="data_table_pricing" columns="3">
<h:outputText value="Title"/>
<h:inputText id="title" value="#{pricingForm.title}" validatorMessage="Value is too big.">
<f:validateLength minimum="0" maximum="40" />
<f:ajax event="change" render="@form"/>
</h:inputText>
<h:message id="title_message" for="title" style="color:red"/>
<!-- // -->
<h:outputText value="First name"/>
<h:inputText id="first_name" value="#{pricingForm.firstName}" validatorMessage="Value is too big.">
<f:validateLength minimum="0" maximum="40" />
<f:ajax event="change" render="@form"/>
</h:inputText>
<h:message id="first_name_message" for="first_name" style="color:red"/>
<!-- // -->
<h:outputText value="Last name"/>
<h:inputText id="last_name" value="#{pricingForm.lastName}" validatorMessage="Value is too big.">
<f:validateLength minimum="0" maximum="40" />
<f:ajax event="change" render="@form"/>
</h:inputText>
<h:message id="last_name_message" for="last_name" style="color:red"/>
<!-- // -->
</h:panelGrid>
<h:commandLink value="reset" class="link" type="reset" style="margin: 20px;">
<f:ajax execute="@form" render="@form"/>
</h:commandLink>
<h:commandLink value="Next" class="link" style="margin: 20px;" actionListener="#{pricingForm.calculatorPage()}">
<f:ajax execute="@form" render="@form"/>
</h:commandLink>
</h:form>
当我在多个输入字段中插入大值时,我只看到一条错误消息。看起来在呈现表单时未保存旧值。你帮我解决这个问题吗?
