    text
    copied!<p>I am new to Struts2, trying to use <code>addFieldError</code> in my form with <code>&lt;s:select&gt;</code> tag. I have a form in which i have to select a value from a drop-down list. First time when this form is shown, the response comes from an Action class, in which i have created a List. In my form i am printing that list in a drop-down using <code>&lt;s:select&gt;</code> tag like this:</p> <pre class="lang-xml prettyprint-override"><code>&lt;s:form action="clientselect"&gt; &lt;h2&gt;Select Client to add the case :&lt;/h2&gt; &lt;table&gt; &lt;s:select list="list" headerKey="-1" headerValue="Select Client" label="Select Client" tooltip="Select the desired client" name="client"&gt; &lt;/s:select&gt; &lt;tr&gt;&lt;td&gt;&lt;s:submit value="Register Case" theme="simple" align="right"/&gt;&lt;/td&gt; &lt;td&gt;&lt;s:reset value="Reset" theme="simple" align="right"/&gt;&lt;/td&gt;&lt;/tr&gt; &lt;/table&gt; &lt;/s:form&gt; </code></pre> <p>"pageinclude=ancar" prints this form.</p> <p>struts.xml</p> <pre class="lang-xml prettyprint-override"><code>&lt;action name="clientselect" class="casediary.JudicialCaseRegisterValidation" method="execute"&gt; &lt;result name="addcase"&gt;user.jsp?pageinclude=ncr&lt;/result&gt; &lt;result name="error"&gt;user.jsp?pageinclude=errancar&lt;/result&gt; &lt;result name="input"&gt;user.jsp?pageinclude=ancar&lt;/result&gt; &lt;result name="loggedout"&gt;index.jsp?pageinclude=relogin&lt;/result&gt; &lt;/action&gt; </code></pre> <p>in JudicialCaseRegisterValidation.java</p> <pre class="lang-java prettyprint-override"><code>public void validate() { if(client==null || client.equals("-1")) addFieldError("client", "This field can not be blank."); } </code></pre> <p>All is working fine. error condition is satisfied and in result i am getting "input". Error message is also printing BUT THE VALUES IN THE DROP-DOWN LIST ARE GONE. THE LIST IS PRINTING EMPTY. Because this time response is not coming from the Action class in which the List is set.</p> <p>then i changed my struts.xml to send the request to the Action class from the <code>&lt;result&gt;</code> like this:</p> <pre><code>&lt;result name="input" type="redirect"&gt;link.action&lt;/result&gt; </code></pre> <p>"link.action" is what that is sending the request in Action class to create the List and printing that form.</p> <p>But this time the form is just printed again &amp; no error message is printed.</p> <p>I want that List be printed again and also the error message besides it. Please Tell How.?</p>
