I've a custom grid and I'm using zul to define its column and row composition. I just want to be able to access the row renderer so that if a custom attribut is set to True, I will add a checkbox in front of the row.

When I get the Row in afterCompose they have not yet been rendered, so adding the checkbox then doesn't work.

I tried getting the default renderer but getRowRenderer() return null if the default is used. My idea was to add a wrapper renderer and on its render method add a checkbox to the row before calling the default renderer render method.

And everything is package or private, so annoying =/

Does anyone has an idea how to do that?

=> I want to add checkbox in front of row dynamicaly when a custom attribut of my grid is set to true while still using zul to define my grid layout.

I wanted to avoid impacting the zul / template of the grid.

Went with overriding the onInitRender method, was fairly simple in the end.

@Override
public void onInitRender() {
    super.onInitRender();
    if (withCheckbox) {
        for (Component row : getRows().getChildren()) {
            Checkbox checkbox = new Checkbox();
            row.insertBefore(checkbox, row.getFirstChild());
        }
    }
}
