Render element and block using one method
Is it possible for component to render it's tag from
parent component with informal parameters and return a
block to render inside it?
The following code throws an exception while tapestry
modifies the component class.
Object beginRender(MarkupWriter writer) {
writer.element(resources.getElementName("div"));
resources.renderInformalParameters(writer);
return myBlock;
}
Method which returns void with writer.element() inside
it works. And returning block without writer.element()
works. Both of them together do not work. The problem
seems to be with accessing ComponentResources.
Is it a tapestry bug, or such combination is not
supported? What are the alternatives?
Thanks in advance,
Imants Firsts

Thanks!
Changing the return type from Object to Block solved
the problem.

What version of Tapestry are you using? This works in 5.0.11. Do you
have the matching afterRender block to close the div?
public Block beginRender(MarkupWriter writer) {
writer.write("Something else");
String elementName = _resources.getElementName("div");
writer.element(elementName);
_resources.renderInformalParameters(writer);
return _blockParam;
}
public void afterRender(MarkupWriter writer) {
writer.end();
}
