Using the RCP Designer 2.2.0 version, I can create Named Expressions and
User Properties. However, I have found no examples that will allow me to
successfully access either of those in scripts or in Dynamic Text. Are
these retrievable from the Designer yet?

Hi Richard
Because you have defined your name expression on the table.
this.getNamedExpressionValue will get the dynamic text's named expression.
So you should get table's namedexpression(dynamic text->cell->table
footer->table):
this.valueExpr=this.getParent().getParent().getParent().getN amedExpression( "MyNamedExp")
