hhmmmm,
the isEnabled() of the AttributeAppender is a really cool tool.
I used it in another place.
I have a StyledDataTable that overridden onComponentTag:
@Override
protected void onComponentTag(ComponentTag tag) {
super.onComponentTag(tag);
if (dataProvider.size() == 0) {
CharSequence oldClassName = tag.getString("class");
if (oldClassName == null || oldClassName.equals("")) {
tag.put("class", "emptyTable");
} else {
tag.put("class", oldClassName + " " + "emptyTable");
}
}
}
And instead, I put in the constructor:
add(new AttributeAppender("class", true, new Model("emptyTable"), "
") {
private static final long serialVersionUID = 1L;
@Override
public boolean isEnabled(Component component) {
return (EurekifyDataTable.this.dataProvider.size() == 0);
}
});
That is so much better ..
