Sorry for being dense, but my problem seems to be with the following:
public void writeLabelPrefix(IFormComponent component,
IMarkupWriter writer, IRequestCycle cycle) {
writer.begin("label");
if (isInError(component)) {
writer.attribute("class", "error");
} else {
writer.attribute("class", "required");
}
writer.print(" * ");
}
Ideally, I don't want to have to write write writer.begin("label"),
because I don't want two labels. I just want to hook into the one
that Tapestry wraps around @FieldLabel. With 3.0.3, it didn't do
this. In fact, nothing was written around a field label. With 4.0, I
end up with:
<label class="required"> * <label for="username">Username</label>:</label>
Sure I could use some css (label label { font-style: bold }), but I'd
rather have:
<label class="required" for="username"> * Username:</label>
Is that possible? Does anyone have a ValidationDelegate like the one
from Tapestry in Action that works with 4.0? Sorry if I'm asking a
dumb question and the answer is too simple for me to see. ;-)
