Hi,
The contrib:Table columns need to be serialized for several reasons
(e.g. they are a part of the table model and may reside in the session,
or they need to be serialized into hidden fields to preserve the form
structure, etc).
On the other hand the ExpressionTableColumn has an
OgnlTableColumnEvaluator as a member, which contains an
ExpressionEvaluator -- a non-serializable entity provided by HiveMind
(it used to be a singleton before).
As a result, ExpressionTableColumn is not serialized and deserialized
fully.
If the places that used the evaluator had access to the IRequestCycle,
the answer would be obvious, but unfortunately they do not.
Could one suggest a good solution of that problem?
Thank you in advance...
