TYPO3 Core

Bug #90083

Updated by Ralf Zimmermann over 4 years ago

There are scenarios in which the same form is rendered several times even though it is only output once on the page. 
 Assuming there is a form plugin with a form with validators on form elements on colPos 10, the following setup would render the plugin twice and output the second rendered plugin. 

 setup.typoscript 

 <pre><code class="text"> 
 page = PAGE 
 page { 
     10 = FLUIDTEMPLATE 
     10 { 
         file = EXT:site_package/Resources/Private/Templates/Index.html 

         variables { 
             content-col-10 < styles.content.get 
             content-col-10.select.where = colPos=10 
         } 
     } 
 } 

 lib.getSomeColPos = CONTENT 
 lib.getSomeColPos { 
     table = tt_content 
     select.where = colPos=10 
     select.orderBy = sorting 
 } 
 </code></pre> 

 EXT:site_package/Resources/Private/Templates/Index.html 

 <pre><code class="html"> 
 <f:cObject typoscriptObjectPath="lib.getSomeColPos"/> 
 </code></pre> 

 The result is that the validators are missing in the 2nd rendered form. 
 This is because when the validators are added, a runtime cache is used to prevent validators from being added twice (needed due to internal processes). twice. 
 When rendering the same 2. form no more validators are added because the form element is not identified clearly enough. 

 A simple test to fake such a scenario without much effort would be: 

 setup.typoscript 

 <pre><code class="text"> 
 page = PAGE 
 page { 
     10 = FLUIDTEMPLATE 
     10 { 
         file = EXT:site_package/Resources/Private/Templates/Index.html 

         variables { 
             content < styles.content.get 
             content-foo < styles.content.get 
         } 
     } 
 } 
 </code></pre> 

 EXT:site_package/Resources/Private/Templates/Index.html 

 <pre><code class="html"> 
 {content-foo -> f:format.raw()} 
 </code></pre> 

 or 

 setup.typoscript 

 <pre><code class="text"> 
 page = PAGE 
 page { 
     10 = FLUIDTEMPLATE 
     10 { 
         file = EXT:site_package/Resources/Private/Templates/CustomContentElement.html 
         settings { 
             persistenceIdentifier = 1:/form_definitions/test.form.yaml 
         } 
         extbase.pluginName = Form 
         extbase.controllerExtensionName = Formframework 
         extbase.controllerName = FormFrontend 
         extbase.controllerActionName = perform 
     } 
 } 
 </code></pre> 

 EXT:site_package/Resources/Private/Templates/CustomContentElement.html 

 <pre><code class="html"> 
 <formvh:render persistenceIdentifier="{settings.persistenceIdentifier}" /> 
 <formvh:render persistenceIdentifier="{settings.persistenceIdentifier}" /> 
 </code></pre> 

 1:/form_definitions/test.form.yaml 

 <pre><code class="yaml">

         validators:

             identifier: NotEmpty 
       - 
         defaultValue: ''
