Helmut Swaczinna commented on TOBAGO-986:
-----------------------------------------
This should work for both cases:
private UIComponent getFirstSortableChild(List children) {
UIComponent child = null;
for (Iterator iter = children.iterator(); iter.hasNext();) {
child = (UIComponent) iter.next();
if (child instanceof UISelectMany
|| child instanceof UISelectOne
|| child instanceof UISelectBoolean
|| (child instanceof UIInput &&
TobagoConstants.RENDERER_TYPE_HIDDEN.equals(child.getRendererType()))) {
continue;
// look for a better component if any
}
if (child instanceof UIOutput) {
break;
}
if (child instanceof javax.faces.component.UICommand &&
child.getChildren().isEmpty()) {
// use label attribute of UICommand
break;
}
if (child instanceof javax.faces.component.UICommand
|| child instanceof javax.faces.component.UIPanel) {
child = getFirstSortableChild(child.getChildren());
if (child instanceof UIOutput) {
break;
}
}
}
return child;
}
> Sheet can only sort UIOutput - Nothing happend with UILinkCommand and

> Issue Type: Improvement
> Components: Core
> Affects Versions: 1.0.35
> Reporter: Sven Bunge
> Assignee: Bernd Bohmann
> Priority: Minor
> Fix For: 1.0.36, 1.5.0-beta-1, 1.5.0

>
>
> If a column in a sheet is filled with a tc:link (UILinkCommand) or tc:button
> (UIButtonCommand) the Sorter-class is unable to sort the sheet.
> There are several problems with the method Sorter#getFirstSortableChild(..):
> * The children of a UICommand are recursive searched for a tc:out -> the
> algorithm look into the tc:link and tc:button.
> * Only tc:out's are returned from the method
> * .. the caller method invoke(..) get only the value-binding named "value" -
> The UILinkCommand and UIButtonCommand have no value-field.
> I optimized the getFirstSortableChild(..)-Method and introduced a new method
> how returns the ValueBinding.
