andAbstractComponent.getMold()
, which are caller's job.- Overrides:

protected void redrawChildrenDirectly(TagRenderContext rc, Execution exec, java.io.Writer out) throws java.io.IOException
Description copied from class:AbstractTag
Renders the children directly to the given output. Notice it is called only ifAbstractTag.redraw(java.io.Writer)
is going to render the content (HTML tags) directly. If it is about to generate the JavaScript codeAbstractComponent.redrawChildren(java.io.Writer)
