    <p>I have a difficult JSF issue I am trying to solve. Note, I am fairly new to JSF and Java....I have a simple application where users login, select some checkboxes, click submit, add some more info on another page, save to DB and logout. </p> <p>In my Production env, I am seeing instances where user session data is getting crossed or cached and pickup by a subsequent user session. For example, User A enters data, then User B enters data and upon reviewing his data, he sees stuff User A entered. Of course, I cannot recreate this in test.</p> <p>I am using jsf 1.2._12, richfaces 3.3.2, and spring 2.5.6. The app server is JBoss 5. </p> <p>All of my JSF managed-beans are session scoped. This particular managed bean calls a spring bean as my Business object which is session scoped, which ultimately calls a DAO that is singleton. </p> <p>Here the relavant faces-config info</p> <pre><code>&lt;managed-bean&gt; &lt;description&gt;ContactBean&lt;/description&gt; &lt;managed-bean-name&gt;ContactBean&lt;/managed-bean-name&gt; &lt;managed-bean-class&gt;com.package.ContactBean&lt;/managed-bean-class&gt; &lt;managed-bean-scope&gt;session&lt;/managed-bean-scope&gt; &lt;managed-property&gt; &lt;property-name&gt;dataElementBO&lt;/property-name&gt; &lt;value&gt;#{dataElementBO}&lt;/value&gt; &lt;/managed-property&gt; &lt;managed-property&gt; &lt;property-name&gt;attributeBO&lt;/property-name&gt; &lt;value&gt;#{attributeBO}&lt;/value&gt; &lt;/managed-property&gt; &lt;managed-property&gt; &lt;property-name&gt;dataElement2BO&lt;/property-name&gt; &lt;value&gt;#{dataElement2BO}&lt;/value&gt; &lt;/managed-property&gt; &lt;managed-property&gt; &lt;property-name&gt;submissionBO&lt;/property-name&gt; &lt;value&gt;#{submissionBO}&lt;/value&gt; &lt;/managed-property&gt; &lt;managed-property&gt; &lt;property-name&gt;selectedList&lt;/property-name&gt; &lt;property-class&gt;java.util.ArrayList&lt;/property-class&gt; &lt;list-entries /&gt; &lt;/managed-property&gt; &lt;managed-property&gt; &lt;property-name&gt;enteredContact&lt;/property-name&gt; &lt;property-class&gt;java.util.ArrayList&lt;/property-class&gt; &lt;list-entries /&gt; &lt;/managed-property&gt; &lt;/managed-bean&gt; </code></pre> <p>And my app-Context for the spring bean getting called</p> <pre><code>&lt;bean id="submissionBO" class="com.package.submissionBOImpl" scope="session"&gt; &lt;property name="submissionDAO"&gt; &lt;ref bean="submissionDAO" /&gt; &lt;/property&gt; &lt;/bean&gt; </code></pre> <p>In viewing my webserver logs, this issue occurred when User A and B weren't even logged in at the same time. User A logged out and then User B logged in almost 20 minutes later. </p> <p>I don't understand how the use of session scoped beans could possibly cross in other users data... is there something I don't understand about how these are scoped? I can attach some mocked up code if needed. Thanks in advance! </p>

    1. COYou aren't assigning session scoped data as a `static` field in some class, are you? As to the local testing, just spawn different browsers on the same site at the same time, like Firefox, Chrome, Safari and/or IE.

    2. COThe only statics I am using in the managed bean or spring bean are for my log and a reg ex pattern used to check a phone number format in a validator method.

    3. COSounds spooky and scary. Why did you use spring instead of seam? Seam is 100 folds better for jsf apps.

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).
