Different ways of using seam s:decorate and s:validate – Sample are based on Seamgen based applications.

1. <s:decorate> without template attribute and with <s:validateAll>, requiredMessage, validateLength samples.
   

   <s:decorate>
   

   <s:validateAll>
   

   <div class=”prop”>
   

   <s:label id=”editLabel” styleClass=”#{invalid?’errors’:”}”>
   

     created by
   

     <s:span styleClass=”required” rendered=”true”>*</s:span>
   

     </s:label>
   

   <span id=”editSpan” class=”#{invalid?’errors’:”}”>
   

     invalid value > #{invalid}
   

   <ice:inputText id=”createdById” requiredMessage=”This field value is required.” partialSubmit=”true” size=”100″ maxlength=”130″ value=”#{userHome.instance.createdBy}”>
   

     <f:validateLength maximum=”5″ minimum=”1″ />
   

     </ice:inputText>
   

     </span>
   

     <s:message styleClass=”error errors” />
   

     </div>
   

     </s:validateAll>
   

     </s:decorate>
   

 

Note: The reason being used s:decorate is that #{invalid} and #{required} are available inside s:decorate; #{required} evaluates to true if you have set the input component being decorated as required, and #{invalid} evaluates to true if a validation error occurs.

 

 

1. <s:decorate> without template attribute and <s:validateAll>, validateLength and with only required=”true” also work!!!.
   

 

<s:decorate>

<div class=”prop”>

<s:label id=”editLabel” styleClass=”#{invalid?’errors’:”}”>

  created by

  <s:span styleClass=”required” rendered=”true”>*</s:span>

  </s:label>

<span id=”editSpan” class=”#{invalid?’errors’:”}”>

  invalid value > #{invalid}

<ice:inputText id=”createdById” requiredMessage=”This field value is required.” partialSubmit=”true” required=”true” size=”100″ maxlength=”130″ value=”#{featureSetHome.instance.createdBy}”>

  </ice:inputText>

  </span>

  <s:message styleClass=”error errors” />

  </div>

  </s:decorate>

 

 

1. With just <s:decorate>, required=”true”, s:message and without requiredMessage attribute.
   

   <s:decorate>
   

   <div class=”prop”>
   

   <s:label id=”editLabel” styleClass=”#{invalid?’errors’:”}”>
   

     created by
   

     <s:span styleClass=”required” rendered=”true”>*</s:span>
   

     </s:label>
   

   <span id=”editSpan” class=”#{invalid?’errors’:”}”>
   

     invalid value > #{invalid}
   

   <ice:inputText id=”createdById” partialSubmit=”true” required=”true” size=”100″ maxlength=”130″ value=”#{featureSetHome.instance.createdBy}”>
   

     </ice:inputText>
   

     </span>
   

     <s:message styleClass=”error errors” />
   

     </div>
   

     </s:decorate>
