I had a similar problem. What I ended up doing was returning Object from the
beginRender method and either returning the block parameter or using the
writer and returning null.
To simulate looping you can store your tokenizer in a page variable and
return st.hasMoreTokens from afterRender, if it's false it will call
beginRender again.
private StringTokenizer st;
@Parameter
private Block _blockParam;
void setupRender() {
st = new StringTokenizer(template, " ");
}
@BeginRender
final Object begin(MarkupWriter writer)
{
String token = st.nextToken();
if("TEST".equals(token))
{
return _blockParam;
}
else
{
writer.writeRaw(token);
}
return null;
}
@AfterRender
boolean after(MarkupWriter writer) {
return !st.hasMoreTokens(); // if it has more tokens go back to begin
}
It doesn't fit for all cases, but something like that should work for the
simple case you laid out...
