Question concerning JSON generation DateTime -> Null

Hi Arnaud, since 3Month or so JSON Output write null for TDateTime if Date is 0
Before it wrotes a empty String "" in JSON Output.

Is it possible to enable old Feature OnDemand ?
Because we have old SynCrossplatform Clients throwing exception implicit converting Variant Null to String

For new Clients i added this to SynCrossplatformJSON:

function Iso8601ToDateTime(const Value: Variant): TDateTime; overload;
function Iso8601ToDateTime(const Value: string): TDateTime; overload;

Re: Question concerning JSON generation DateTime -> Null

I understand your concern.

Please try with
https://github.com/synopse/mORMot2/commit/1c9175125

Sorry for the breaking change.
It was a user request, and I did not think about breaking legacy clients.

Re: Question concerning JSON generation DateTime -> Null

Did you try to add it to the global DEFAULT_WRITEOPTIONS[] variable?

I have fixed the ui.pdf compilation.
Thanks for the notice.
