Magento 2 Block returns value of 1

[pinkdigital]

I have inherited a project that has the following code:

       return $this->getLayout()
            ->createBlock(CategoryBlock::class)
            ->setData([
                'title' => $title ? sprintf($title, $category->getName()) : null,
               'category_id' => $category->getId(),
                'description' => $description ? sprintf($description, $category->getName()) : null,
            ])->toHtml();

The description is working by using $block->getDescription() as I would expect. The $block->getTitle() is not returning the value expected, instead it is return the number 1. Can anyone spot the problem as I have tried various things but it is not working. The project has to use 2.2.7 so need to debug in this version.

Hello @pinkdigital 

Can you use directly class name instead of 

CategoryBlock::class

e.g

Vendor\Module\Block\Name

Thanks

Thanks for your help. It didn't resolve the problem so I had a deeper look in to the code.

The problem was caused by the previous developer returning $this->hasData('title') instead of $this->getData('title'); hence the value of 1 (true).
