I have troubles with this one, good to hear its my fault. But which one?

Here is a little Persistent.nrx causing troubles. If I replace the indexed string with normal Rexx (or a
Hashtable) the class LongTermStorage is written to disk without Exception.

-- Persistent.nrx
pers = LongTermStorage()
os = ObjectOutputStream(FileOutputStream('storage.dat'))
os.writeObject(pers)       -- WRITE OBJECTS WITH ONE CALL
os.close()

class LongTermStorage implements Serializable
properties private
   counter  = Rexx '4711' -- is ok
   IndexedR = Rexx '' -- gives java.io.NotSerializableException: netrexx.lang.RexxNode

method LongTermStorage()
       IndexedR['netrexx']='super'      -- save this to disk
       say counter
       say IndexedR['netrexx']

********************* end Persistent.nrx

runnig this I obtain:

[D:\NetRexxbsp\NRWWW\temp]java Persistent
4711
super
java.io.NotSerializableException: netrexx.lang.RexxNode

Ciao Kai

P.S. Unlike Mike I am VERY pleased with NetRexx and its progress. If only everything would be so
intuitive and stable. Apologies accepted ;=)
