Leonardo Uribe commented on MYFACES-4046:
-----------------------------------------
After looking the code and think about it, I think the best way to do it is in
this way:
{code:java}
Map<String, Object> attributes = new HashMap<String, Object>();
attributes.put("src", "/addSimpleIncludeVDL_2_1.xhtml");
Map<String, Object> paramsMap = new HashMap<String, Object>();
paramsMap.put("param1", "value1");
paramsMap.put("param2",
facesContext.getApplication().getExpressionFactory().createValueExpression(
facesContext.getELContext(), "#{testBean.param2}"
,String.class));
attributes.put("params", paramsMap);
UIComponent component = vdl.createComponent(facesContext,
"http://java.sun.com/jsf/facelets";,
"include", attributes);
{code}
The idea is add a "virtual" parameter called "params" to ui:include,
ui:decorate and ui:composition. I mean "virtual" because this phantom param is
not on the facelet tag class, instead is read directly by the compiler only on
vdl.createComponent(...) case. The reason is ui:param behavior is tightly bound
to the parent tag, in a way that you can define ui:param without be aware of
the parent.

> Key: MYFACES-4046
> URL: https://issues.apache.org/jira/browse/MYFACES-4046
> Project: MyFaces Core
> Issue Type: Improvement
> Reporter: Leonardo Uribe
> Priority: Minor
>
> Since 2.2 it is possible to call vdl.createComponent and pass an ui:include
> in this way:
> {code:java}
> Map<String, Object> attributes = new HashMap<String, Object>();
> attributes.put("src", "/addSimpleIncludeVDL_1_1.xhtml");
> UIComponent component = vdl.createComponent(facesContext,
> "http://java.sun.com/jsf/facelets";,
> "include", attributes);
> {code}
> It works but there is no way to pass parameters as described in:
> http://stackoverflow.com/questions/35178151/programmatically-include-xhtml-fragment-in-myfaces
> The question is how to pass ui:param components. Maybe use
> vdl.createComponent and pass ui:param, but note ui:param does not have an
> underlying component, because it is a facelet tag, but a standard notation
> for this case could be useful.
