Wt

After migrating the development from wt3 to wt4 the fileupload progress is not available any more. The progressbar is not rendered and the wthttp log does not show single chunks during the upload process.

The piece of code is straightforward and did not change since wt3 except the transition to unique_ptr:

fileUpload_ = newFileDialog_->contents()->addWidget(std::make_unique<Wt::WFileUpload>());
fileUpload_->setMultiple(false);
fileUpload_->setProgressBar(std::make_unique<Wt::WProgressBar>());
fileUpload_->changed().connect(this, &MyClass::onFileUploadChanged);
fileUpload_->uploaded().connect(this, &MyClass::onFileUploaded);
fileUpload_->fileTooLarge().connect(this, &MyClass::onFileTooLarge);

Thanks
