Hi,

do you have made sure that your manage-bean "FailureWrapper" has a
default no-arg constructor? It seems that the jsf managed-bean
facility cannot create a new instance of the bean.

cheers,

Gerald

Hello

I have checked the archive but can't find a solution for my problem.

I have a t:dataTable which has rows. On the first column of each row I
have a checkbox which should be automatically checked dependend of
another checkbox. For instance, if I have a checkbox in the tableheader
an press the "mark all checkbox" all checkboxes should be selected. I
got the following exception:

I got the following exception.

java.lang.InstantiationException: com.rsp.web.base.FailureWrapper

Could you tell me what I have done wrong? Thanks a lot for your help

<t:column style="vertical-align:top">

The failureWrapper and failures are defined as managed beans.

<managed-bean>
        <managed-bean-name>failures</managed-bean-name>

<managed-bean-class>com.rsp.web.base.Failure</managed-bean-class>

        <managed-bean-scope>session</managed-bean-scope>
    </managed-bean>
    <managed-bean>
        <managed-bean-name>failureWrapper</managed-bean-name>

<managed-bean-class>com.rsp.web.base.FailureWrapper</managed-bean-class>
        <managed-bean-scope>request</managed-bean-scope>
    </managed-bean>

com.rsp.web.base.FailureWrapper has the following methods:

 public HtmlSelectBooleanCheckbox getCheckBox() {
        return this.checkBox;
    }

    public void setCheckBox(HtmlSelectBooleanCheckbox checkBox) {
        this.checkBox = checkBox;
    }
