Reading non-existent properties on declare page throws ReadOnlyException
To re-word a question from 2013...
In Pega, the common methods for getting properties from a ClipboardPage (getString() or the JSP functionality) will actually create the property if missing (and return the empty string).
This is problematic when working with Declare Pages. Suppose, for example, you expect a Declare Page to have a list of pxResults, but it has none. Defensive coding can sometimes avoid this (i.e., wrap a conditional around an iteration), but this ought to be more automated.
As Declare Pages which are read-only; the ReadOnlyException is thrown.
Was this problem ever fixed in a v6.x hotfix? Was it addressed in v7?

There appear to be hotfixes for v6.2/sp2 & v6.3/sp1, FWIW.
Hi, in Pega 7 reading properties from a read-only data page no longer results in an exception, though it may result in the creation of blank properties on the data page.
