{$this->hasBlock('test')} yields different result than {hasBlock('test')}

Version: 3.0.13

Bug Description

{$this->hasBlock('test')} yields different result than {hasBlock('test')}.

Relevant code:

latte/src/Latte/Essential/CoreExtension.php

Line 194 in 462444d

'hasBlock' => fn(string $name): bool => $this->template->hasBlock($name),

Lines 379 to 382 in 462444d

    
           public function hasBlock(string $name): bool 
        
           { 
        
           	return isset($this->blocks[self::LayerLocal][$name]) || isset($this->blocks[self::LayerTop][$name]); 
        
           }

When using {$this->hasBlock()} the LayerTop array has many entries of Latte\Runtime\Block instances (key being the block's name), but it is empty when called using {hasBlock()}. In fact, the whole $this->blocks array only contains another empty arrays in this case.

Steps To Reproduce

default.latte (template of a presenter's action)

{block test}Test{/block}

@layout.latte (main layout)

{$this->hasBlock('test')} {* true *}
{hasBlock('test')} {* false *}

Also, this in @layout.latte doesn't work:

{block test}test{/block}
{dump $this->hasBlock('test')}
{dump hasBlock('test')}

Result:

Which is strange, because on fiddle it works:

https://fiddle.nette.org/latte/#9f34b533f2

I tried to make a failing example on fiddle.nette.org/latte, but I'm not able to simulate the relation between @layout.latte and a presenter/action template.

Expected Behavior

Both approaches have the same result.

Possible Solution

N/A

Thanks, it is working now 👍

Note for anyone updating - if you see this error, don't panic 🙂

The solution is easy - clear latte cache.
