Re: Grid custom no field

Hi guys, so i finally made the GridIndex component. But something is
bothering me and I wonder if I can improve it. The component still need the
page to implement an idx property, i wonder if I can pull it directly from
grid rowIndex parameter. Here's the code for my component.

page tml

<t:grid t:id="grid" t:source="cities" t:row="city" rowIndex="idx"
t:inPlace="true"
t:add="no" t:exclude="id" t:reorder="no" class="table table-striped">
<p:noCell>
<t:mreunionlabs.GridIndex idx="idx" grid="grid"/>
</p:noCell>
</t:grid>

page java properties

@InjectComponent
@Property
private Grid grid;

@Property
private int idx;

The component code

public class GridIndex {

    // Parameters

    @Parameter(required = true)
    @Property
    private int idx;

    @Parameter(required = true)
    @Property
    private Grid grid;

    @BeginRender
    void begin(MarkupWriter writer) {
        int no = grid.getRowsPerPage() * (grid.getCurrentPage() - 1) + idx
+ 1;
        writer.write(String.valueOf(no));
    }

}
