TYPO3 Core

A tricky one that was reported for the YAG extension as well.

What you need:

• FLUIDTEMPLATE
• COA_INT or USER_INT

Example:

page.20 = FLUIDTEMPLATE
page.20 {
  file = fileadmin/fluid.html
  partialRootPath = fileadmin/Partials/
}

page.30 = COA_INT
page.30.10 = TEXT
page.30.10.value = TEST

Contents of the Fluid Template file (fileadmin/fluid.html):

<f:render partial="Test" />

Contents of the Test partial (fileadmin/Partials/Test.html):

HELLO WORLD

Now, call the page (to have it cached) and then call another page that uses that cache - you should see a nice error/exception for handling the COA_INT.

• The Partial handling in the RenderViewHelper will store a compiled version, using Closure in the cache
• Thus, the first call works, but the second one, using the cache will use the Closure
• The serialize($this->cObj) in COA_INT will stumble over the Closure deep down in cObj and fail

Closures have been introduced in Fluid with TYPO3 4.6.
