Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

UUserWidget Serialize bug

Hi
I am trying to serialize a user widget, however every single time I end up in at MemoryArchive line 56:
virtual FArchive& operator<<( class UObject*& Res ) override
{
// Not supported through this archive
check(0);
return *this;
}
Where my Res is some mambojambo material from /Engine/MapeTemplates/Materials
here is my h:
UPROPERTY(EditAnywhere, BlueprintReadOnly, Category = "Test Widget")
UWidgetComponent* TestWidget;
cpp:
TestWidget = CreateDefaultSubobject(TEXT("TestWidget"));
TestWidget->SetupAttachment(RootComponent);
...
if (TestWidget->GetUserWidgetObject())
{
FBufferArchive ToBinary;
TestWidget->GetUserWidgetObject()->Serialize(ToBinary);
}

What I am trying to achieve is to serialize widget, send binary data over TCP and read it back to widget. However as you may know at very first thing Unreal flips. Any ideas ? Cheers!
