Grid component customization
Dear all,
I wanted to customize the GridColumns component, which is embedded
inside the Grid component, by trying different approaches.
Finally I failed, because it was neither possible by a request filter
replacing the GridColumns component at runtime with my customized one,
nor did it work to use an own template for the Grid component pointing
to my customized version of GridColumns.
What is the best way to do this? The GridColumns component is a private
component inside the Grid and I wonder how to replace it.
I even tried to put a complete own Grid component in my application, but
this ends up in the exception, that there is no type coercer available
for my own Grid implementation to the original Tapestry Grids bean
model. And even if this had worked, it would not be a nice way.
Your help is appreciated. Thanks in advance.
Greetings, Eric

Hi Thiago and Chris,
these are very precious hints, using the mixin way would be more elegant
than overwriting the GridRows component, according to my opinion.
Thanks a lot, and yes: the overwrite did work, but I will follow the
mixin way...
Greetings, Erich

There is already a decent amount of RenderNotification mixins present on
the various grid components allowing you to manipulate the MarkupWriter per
row, column and header column.

Another possibility for doing that is to use Tapestry DOM rewriting. You'd
create a mixin, apply it to your grids, and the mixin would have an
afterRender(MarkupWriter writer) method. writer.getDocument() gives you the
Tapestry DOM element tree. From it, you can find the grids, its tags and
change them to your pleasure. tapestry-xpath allows you to find DOM
elements using XPath and may help you in this task.
Have you tried what I suggested (component overriding?)?

Hi Thiago,
Our HTML designer wants to create a fully responsive website based on
Tapestry 5.3.8.
So she asked me, if it would be possible, to render some data attributes
inside the td tags of the grid.

Hello!
Well, you can override a component, you can decorate or advise the
ComponentClassResolver service. Specifically, when
the resolveComponentTypeToClassName(String componentType) method is called,
if componentType.equalsIgnoreCase("GridColumns"), then return the fully
qualified class name of your GridColumns replacement component. Otherwise,
let it return normally. That's basically how ComponentSubstitutor is
implemented inside Tapestry itself.
Just curious: what customizations do you want to do?

Dear Thiago,
first thanks for this solution, but can you please propose a solution
which works under Tapestry 5.3.8? This would be great.
Anyway, I tried to migrate our applications to 5.4.3 yesterday and
nearly succeeded, but only nearly, due to problems with the removed
javassist lib.
ut this would be another topic in this support list.
Thanks and Best Regards
Erich

Contribute to the ComponentOverride distributed configuration, which is a
Map<Class, Class>, the key being the component or page or mixin class to be
replaced, the value being the replacement.
Here's an example from Tapestry's test suite:
@Contribute(ComponentReplacer.class)
public static void
overridePageAndComponentAndMixin(MappedConfiguration<Class, Class>
configuration) {
configuration.add(OverridenPage.class, OverridePage.class);
configuration.add(OverridenComponent.class, OverrideComponent.class);
configuration.add(OverridenMixin.class, OverrideMixin.class);
}
