TYPO3 Extbase action called twice

Question

I noticed that on some of my TYPO3 7.6 extensions an action seems to get called twice, for example a listAction. If I put a vardump or an echo there it gets outputted twice, however the template is shown correctly once. I cannot discover any error in the code. The weird thing is on another site it does not happen with the same extension.

What could be the reason for this and how can I debug this?

Could you share your controller code? – Lasse Jan 08 '17 at 09:09 — Lasse, Jan 08 '17 at 09:09

Maybe you are using page.10.variables? Check my answer here what is the best usage of typoscript in fluid templates?

Indeed I found out that in my general site templating setup I used two page.10.variables which looked at .select.where = colPos = 1 Even when the 2nd variable is not in the page template they seem to cause to run things twice. – Jacco van der Post Jan 09 '17 at 09:48

For me non-cacheable action in ext_localconf.php solved the problem

    // non-cacheable actions
    array(
        'ControllerName' => 'list, show, create, update',
        
    )

Maybe the plugin is inserted twice on that page? Create a new plugin on another page and see if theres a double debug, too.

Thanks for your reaction but the plugin is inserted only once. Also on another page. – Jacco van der Post Jan 07 '17 at 14:07
Maybe it is also included somewhere by typoscript? `$this->contentObj = $this->configurationManager->getContentObject();` `$uid = $this->contentObj->data['uid'];` Try to debug the uid. If its the same we can be sure its really the same ContentObject. – Paul Beck Jan 07 '17 at 14:11
It outputs twice the same uid. – Jacco van der Post Jan 07 '17 at 14:22
And when you remove the one debug, both debugs are gone? – Paul Beck Jan 07 '17 at 14:29
Yes they both gone than. – Jacco van der Post Jan 07 '17 at 14:30
Maybe I can take a look with teamviewer when calling on skype? – Paul Beck Jan 07 '17 at 14:46

I noticed something similar when using fluidTYPO3. The cause was that the configuration-section of the fluid-template had to be parsed and executed to build the flexform structure to read and write the flexform-data. So the template might be parsed and executed twice but the php action is only called once. You can test this by dumping some variable in your action with: \TYPO3\CMS\Extbase\Utility\DebuggerUtility::var_dump($data, __FILE__.':L'.__LINE__);
