How to programmatically instantiate a composite component or a tag component ?
Dear all,
how can I programatically instantiate a composite component or a tag
component from a custom component ?
I proceed this way to instantiate a composite component, but I do not
really like it as I use reflection to hijack
FaceletViewDeclarationLanguage methods...
public UIComponent instantiateComposite(String namespace, String
componentName) {
FacesContext ctx = FacesContext.getCurrentInstance();
Resource resource =
ctx.getApplication().getResourceHandler().createResource( componentName
+ ".xhtml", namespace );
UIComponent cc = ctx.getApplication().createComponent( ctx, resource );
UIPanel panel = (UIPanel) ctx.getApplication().createComponent(
UIPanel.COMPONENT_TYPE );
// set the facelet's parent
cc.getFacets().put( UIComponent.COMPOSITE_FACET_NAME, panel );
FaceletFactory ff = (DefaultFaceletFactory)
DefaultFaceletFactory.getInstance();
if(ff == null) {
FaceletViewDeclarationLanguage vdl = new
FaceletViewDeclarationLanguage(ctx);
Method createCompiler = null;
Method createFaceletFactory = null;
try {
createCompiler =
FaceletViewDeclarationLanguage.class.getDeclaredMethod("createCompiler",FacesContext.class);
createFaceletFactory =
FaceletViewDeclarationLanguage.class.getDeclaredMethod("createFaceletFactory",FacesContext.class,org.apache.myfaces.view.facelets.compiler.Compiler.class);
createCompiler.setAccessible(true);
createFaceletFactory.setAccessible(true);
org.apache.myfaces.view.facelets.compiler.Compiler compiler
= (org.apache.myfaces.view.facelets.compiler.Compiler)
createCompiler.invoke(vdl, ctx);
ff = (FaceletFactory) createFaceletFactory.invoke(vdl, ctx,
compiler);
} catch (IllegalAccessException ex) {
Logger.getLogger(SenatDataTableEntryDetail.class.getName()).log(Level.SEVERE,
null, ex);
} catch (IllegalArgumentException ex) {
Logger.getLogger(SenatDataTableEntryDetail.class.getName()).log(Level.SEVERE,
null, ex);
} catch (InvocationTargetException ex) {
Logger.getLogger(SenatDataTableEntryDetail.class.getName()).log(Level.SEVERE,
null, ex);
} catch (NoSuchMethodException ex) {
Logger.getLogger(SenatDataTableEntryDetail.class.getName()).log(Level.SEVERE,
null, ex);
} catch (SecurityException ex) {
Logger.getLogger(SenatDataTableEntryDetail.class.getName()).log(Level.SEVERE,
null, ex);
}
}
try {
Facelet facelet = ff.getFacelet(resource.getURL());
facelet.apply( ctx, panel );
} catch ( IOException e ) {
e.printStackTrace();
}
return cc;
}
How can I do the same stuff in a cleanier way ?
And how can I instantiate a tag component I mean a component declared
the following way :
blah blah
myWonderfulTag
tags/mwl/myWonderfulTag.xhtml
in a taglib.
Thanks in advance,
Ludovic
