[TYPO3-dev] problem with caching after change of the link parameters

[Franz Holzinger]

Hello,

I have made some changes to tt_products in the links so that they have
e.g. tx_ttproducts_pi1[product]=32 instead of the former tt_products=32 .
This problems happens with the latest version from TYPO3 CVS and TYPO3
3.8.1 as well.

I want to make the single view cachable. However now always the same
product is shown in the single view.
What can be the reason for this error?

http://wiki.typo3.org/index.php/Ext_tt_products#Download (I have put it
into CVS)

from class.tx_ttproducts_pi1.php:
class tx_ttproducts_pi1 extends fhlibrary_pibase {
	var $prefixId = 'tx_ttproducts_pi1';	// Same as class name
	var $scriptRelPath = 'pi1/class.tx_ttproducts_pi1.php';	// Path to this
script relative to the extension dir.
	var $extKey = TT_PRODUCTS_EXTkey;	// The extension key.
...
	var $pi_checkCHash = TRUE;
...

case 'SINGLE':
    debug ($this->basket->itemArray, '$this->basket->itemArray',
__LINE__, __FILE__);
    debug ($this->conf['NoSingleViewOnList'],
'$this->conf[\'NoSingleViewOnList\']', __LINE__, __FILE__);
    if (count($this->basket->itemArray) ||
!$this->conf['NoSingleViewOnList']) {
        debug ($theCode, 'set_no_cache in single view!! $theCode',
__LINE__, __FILE__);
        $TSFE->set_no_cache();
    }
    $contentTmp=$this->products_display($theCode, $this->errorMessage,
$error_code);
break;

In this case the cache is used and this is correct now. However always
the same product comes from the cache now.
Strangle it does not even work if I call
TSFE->set_no_cache(). Also in this case the cache is used.

The former (working) version had the same code here.

>> break;


Only the names of the parameters in the links have been changed.
I have cleared all the caches from the backend and frontend. I click on
the two symbols 'Admin functions' in the backend. So the cache must be
cleared now. When I reload the single view page even with another
&tx_ttproducts_pi1[product]=4 paramter then always the same product is
shown in single view again and again.

Is this an error or did I miss something?
