You can add a contribution like:
<contribution configuration-id="ListConverters">
<converter
class="java.lang.String"
object="instance:StringToListConverter" />
</contribution>
Then define a class StringToListConverter implementing TypeConverter to
convert a comman separated string into a List. Of course, you should
expect a List instead of an array:
public abstract class TestPage extends BasePage {
@InjectMeta("my-list")
public abstract List getMyList();
}
Do you consider this simple? If not, you may just do it like this:
public abstract class TestPage extends BasePage {
@InjectMeta("my-array")
public abstract String getMyArrayAsString();
public List getMyArray() {
//call getMyArrayAsString() and convert it to a list.
}
}
