    <p>I am using Struts 2 with tiles for my application. </p> <p>In the application i am using an action class say <strong>'A'</strong> with different action methods like <em>add</em>,*edit*,<em>save</em>,*savesuccess* and so on.<br/><br> In a page, when i am clicking a check box ,i use window.open method to open a pop-up window by calling a action method "edit()" of the action class A which performs some database operation and return the result to the pop-window.<br/> After performing some modification i submit the form to a action method named "save()" in action class A and it return the result page to the same pop-window.<br/> The problem is when i close the pop-window, the action is executed once again and shows null values in console and exception.<br/>I thought it may be due to browser so i try the <strong>event.returnValue=false</strong> on click event in the pop-window but still i am facing the problem.<br> I came to know about the token interceptor in struts2. But when i am using tag in the page , it shows 404 error.<br/>I will be thankful to those who provide some examples related to using token Interceptor in struts2 with tiles.. <br/> Struts.xml</p> <pre><code>&lt;action name="*Com" method="{1}" class="com.act.A"&gt; &lt;result name="add" type="tiles"&gt;add&lt;/result&gt; &lt;result name="edit" type="tiles"&gt;edit&lt;/result&gt; &lt;result name="save" type="tiles"&gt;save&lt;/result&gt; &lt;result name="savesuccess" type="tiles"&gt;savesuccess&lt;/result&gt; </code></pre> <p> </p> <p>Parent Page pop window open code:</p> <pre><code>editwindow=window.open("editCom?id="+id+"&amp;name="+name+"..and son on","edit","width=605px,height=270px,channelmode=no,left=250px,location=no,menubar=no,status=no,titlebar=no,toolbar=no,top=250px,scrollbars=yes,resizable=no"); </code></pre> <p>Popwindow Edit window form submission code</p> <pre><code>&lt;form name="editpage" action="saveCom" method="post"&gt; .......... </code></pre> <p> </p> <p>After clicking the submit button it open a new page on the same popwindow like this</p> <pre><code>&lt;html&gt; &lt;script type="text/javascript"&gt; function check1(){ window.opener.location="savesuccessCom"; } &lt;/script&gt; &lt;body onunload="check1"&gt; &lt;form name="editsave" method="post" action="" &gt; ..... &lt;p&gt;Changes Saved Successfully&lt;/p&gt; &lt;input type="button" name="Saved" id="Save" value="Save" onclick="self.close();event.returnValue=false;"/&gt; &lt;/form&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>Please help me to solve this issues. </p>

    2. COThe issue is between the resulting page and struts2, tiles is just another means of constructing the result so should not play a significant role. You are using ajax to send a request that show in a pop up correct? And when you close that dialogue a second request is sent? If this is the case it is a JS error and has little to do with struts. The token interceptor is a possible solution but fixing a simply JS bug seems more obvious if that is the case.

    3. CO@Quaternion, Thanks for your suggestion. And Sorry i am not using ajax to send request. I am using javascript only. And the second request is send not to the pop up open function , it is calling the form submitting function(In the example, it is calling "saveCom" action again and not the "editCom" action. If possible could you point the javascript error.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
