help upgrading T4 code

Folks,

Any help is appreciated.

Formerly (in T4) OGNL was used to perform delicate property handling and processing.

            PropertyDescriptor beanPropDescriptor = (PropertyDescriptor) Ognl.getValue(
                    "propertyDescriptors.{? name == '" + descriptor.getName() + "'}[0]",
                    Introspector.getBeanInfo(parentClassType));

With the removal of OGNL...

Can someone explain how I would upgrade the above piece of code?

Thanks in advance

You can still use OGNL yourself by independently importing OGNL into your
project.  Tapestry's property expression language doesn't do stuff like
this.

Maybe this will help.  I haven't tried it myself.
