Issue with StringArray property - Jofreeze - 09-24-2018
Hello,
I have an issue reading a property declared as array of strings.
My unit (generated by CrossTalk ClassGen) contains a property AllIDs: StringArray read AllIDsRead:
Code:
function SelectionChangedEventArgs.AllIDsRead: StringArray;
begin
with TRight.GetPropValue(Self, '', 'AllIDs') do try
Result := NET.mscorlib.StringArray(Results.ReadObject);
finally Free; end;
end;When this function is called, I get an exception from:
\CrossTalk\Source\Atozed.CrossTalk.Streams.pas
function TCTStreamReader.ReadObject(aClass: TClass = nil): TObject;
-> raise ECTException.Create('Unknown type found during unboxing.');
because xType = dtObjectList {205}
I also have a function returning an StringArray (not a property), and this one works without error:
Code:
function FAL_GAN_LINK.GetAllDataRecordsIds: StringArray;
begin
with TRight.MethodCall(Self, '', 'GetAllDataRecordsIds', 0) do try
Result := NET.mscorlib.StringArray(Results.ReadObject);
finally Free; end;
end;with xType = dtNewObject {206} in ReadObject.
Is it a bug with StringArray properties?

Can you make a simple ready to run demo (console project please) and send me the DPR and CTP file? You can code it all in the DPR to avoid even needing a .pas file.

Hello,
It took some time, but the sample project is here.
Can you take a look at it?
Thanks

What version of Delphi are you using? This project when I loaded it said it wanted to upgrade from D2007. D2007 has not been supported by CrossTalk for several years.

We use Delphi 10.2. I didn't include .dproj file in zip, it may be the reason of message?
RE: Issue with StringArray property - kudzu - 02-12-2019
Possibly. I will proceed without it. I just needed to verify that you were not using an old unsupported IDE.

Is it correct that this assembly is compiled as x64 only? If so is there a reason for this? Except in rare cases, .NET assemblies should be ANY and not X64 or X86.
CrossTalk does support X64, but it takes me a lot longer to debug as I have to change the dev test environment.
I assume this is a test assembly of yours? If so, is it possible to rebuild as ANY instead of X64?

// Global type: <Module>
// Architecture: x64
// Runtime: .NET 4.0

The dll just contains MyClass.cs, you can recompile it.
This one is compiled with ANY.

Thanks. My dev day is already scheduled today but I will get to this as soon as I can.
RE: Issue with StringArray property - kudzu - 02-26-2019
I've scheduled this into my dev day today.
