Helmut Swaczinna reopened TOBAGO-465:
-------------------------------------


The cast of the value binding in getTabIndex() should be Number:

java.lang.ClassCastException: java.lang.Long
        at org.apache.myfaces.tobago.component.UISelectBoolean.getTabIndex(UISelectBoolean.java:70)

Because when you have a numeric exprsssion in the value binding it is evaluated to Long by EL.
And as far as I know there's no cast in EL.

I need this for example in a foreach loop:

tabIndex="#{${status.index} * 5 + 1}"


This code should always work:

  public Integer getTabIndex() {
    if (tabIndex != null) {
      return tabIndex;
    }
    ValueBinding vb = getValueBinding(ATTR_TAB_INDEX);
    if (vb != null) {
      return Integer.valueOf(((Number) vb.getValue(getFacesContext())).intValue());
    } else {
      return null;
    }
  }

> now I would like to set tabindex to correct this different, it this possible?
> [Answer]
> Added support for html tabindex attribute for all input component, button and links.  You can specify an int directly or you
> can use a value binding to an Integer property in a bean.
> Source code is attached.
> Example:
> <tc:page id="inputPage" width="300px" height="300px"
>     focusId="">
