SmartMS 2.2.0.3999 with mORMot throws an exception

warleyalex · 2015-04-26 14:14:58

I can't use anymore crossplatform with smart v2.2.0.3999 anymore. Now, I'm getting this this nasty error:

Compilation failed [Failed to build project: Internal error. Code-generator threw exception EVariantInvalidOpError with message Invalid variant operation] error

some changes at SynCrossPlatformREST:

const
/// the first field in TSQLFieldBits is always ID/RowID
//ID_SQLFIELD: TSQLFieldBit = 0;
ID_SQLFIELD: TSQLFieldBit = TSQLFieldBit(0);

constructor TRTTIPropInfos.Create(const PropNames: array of string;
const PropKinds: array of TSQLFieldKind);
var name: string;
p: integer;
prop: TSQLModelInfoPropInfo;
begin
prop := new TSQLModelInfoPropInfo;
prop.Name := 'RowID'; // first Field is RowID
Props.Add(prop);
for name in PropNames do begin
prop := new TSQLModelInfoPropInfo;
prop.Name := name;
Props.Add(prop);
end;
PropCache := new JObject;
for p := 0 to high(Props) do begin
prop := Props[p];
prop.FieldIndex := TSQLFieldBit(p);
if (p>0) and (p<=length(PropKinds)) then
prop.Kind := PropKinds[p-1] else
prop.Kind := sftUnspecified;
PropCache[uppercase(prop.Name)] := prop;
end;
end;

Yes...
The new version broke some things at the language level.

I would like the 2.2 revision to be stabilized before supporting it fully.

Your feedback is welcome!

I can see a little light what's raising this nasty Compilation failed [Failed to build project: Internal error. Code-generator threw exception EVariantInvalidOpError with message Invalid variant operation] error with SmartMS2.2

The following code bellow, I can compile successfully using Smart2.1, but not with Smart2.2.

Code to reproduce:

procedure TForm1.W3Button1Click(Sender: TObject);
var Call: TSQLRestURIParams;
begin
  CallBackGetB('Auth',['UserName','fAuthentication.User.LogonName','Session','fAuthentication.SessionID'],Call);
end;

procedure TForm1.CallBackGetB(const aMethodName : String;
                                const aNameValueParameters: array of const;
                                var Call: TSQLRestURIParams;
                                aTable: TSQLRecordClass=nil;
                                aID: TID = 0);
begin{ }end;

Did you ask for support in the SMS forums?

Their forums usually does not give you feedback, it seems really inactive. Anyway, I've started a new thread

Hi there,
Smartmobile team have deleted my thread http://forums.smartmobilestudio.com/ind … nal-error/ I asked support to smartmobile team about project WebForm, and a guy named Primoz Gabrijelcic said that he successfully can compile the project using SmartMS 2.2.0.3999 beta2.

Here is the full source attacked.
https://smartmobilestudio.zendesk.com/a … ebForm.zip

Unfortunately, in my old Windows XP SP3, I always I get this internal error Message: Compilation failed [Failed to build project: Internal error. Code-generator threw exception EVariantInvalidOpError with message Invalid variant operation] error

Apparently, this project is working fine under Windows 7, but can not confirm this.

I spent hours to solve this obscure error Compilation failed [Failed to build project: Internal error. Code-generator threw exception EVariantInvalidOpError with message Invalid variant operation] error and finally SMS Client 2.1 and 2.2 worked flawless for me This very complex issue was solved with a simple nil

Passing a value to the method, any expected value, even nil, overrides the default. If you want the default,
omit the argument. The default parameter is used when the parameter isn't provided, but this behavior does not always occur with Smart 2.2, the compiler spits this nasty error, I found that you have explicitly to pass nil argument when a method signature is complex.

Patch for Crossplatform files, project27, project 29:
