    <p>I have a problem, with JSF and Primesfaces. I have a form with a list like the:</p> <pre><code>&lt;h:form&gt; &lt;h:outputText value="Filtrer par client" for="filtreClient" /&gt; &lt;p:selectOneMenu id="filtreClient" value="#{actionBean.action.codeClient}" effect="fade"&gt; &lt;f:selectItem itemLabel="Sélectionnez" itemValue="" /&gt; &lt;f:selectItems value="#{clientDao.listeClient}" /&gt; &lt;/p:selectOneMenu&gt; &lt;/h:form&gt; </code></pre> <p>It returns me this <code>error ==&gt;SEVERE: javax.faces.FacesException: Erreur d’argument : le paramètre «text» est null.</code>(wich means that the parameter "text" is null). What I don't understand is that i don't have a parameter text in my application and what parameter? Parameter from a method? from a <code>httpRequest</code>?</p> <p>Have you ever seen that kind of error?</p> <p>Here is my stack trace :</p> <pre><code>SEVERE: javax.faces.FacesException: Erreur

    1. COEnglish is the lingua franca in programming. It's strongly recommended to reconfigure your development enviornment to use English instead of French. When you Google exact error messages in English, then you will get many many more helpful results/hints. The same applies to posting questions here on Stack Overflow. You will get much more chance in getting helpful answers if the code (class/method/field names, etc) and the error messages are entirely in English.

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).
