Actually I have began using the nested form as follows:
<form wicket:id="rootForm">
<table wicket:id="nestedForm">
</table
</form>
But then I must override as follows (to avoid the form's "invalid tag
name" exception):
protected void onComponentTag(ComponentTag tag) {
tag.setName("form");
super.onComponentTag(tag);
tag.setName("tr");
}
This way I do not need to override the renderPlaceholderTag because it
uses the tag name given in the markup.
I wonder if (nested) forms should simply be allowed to have any tag
name the programmer desires?
Meanwhile, I opened the jira issue:
https://issues.apache.org/jira/browse/WICKET-2166
