It seems that HMENU has a bug when using a userFunc that returns a too
big array. If the number of results is limited, then it works perfectly.
If I have around 350 items, it fails and I get a blank page. Strange
enough, it doesn't raise an error condition. Moreover, the admin pannel
is still displayed, and seems to show the proper content of the menu.

Any idea?

Olivier

I have the following typoscript code in a TemplaVoilà data structure for
a page:

20 = HMENU
20.special = userfunction
20.special.userFunc =
tx_osprayercyclemenus_pi1->generateFilteredMenuFromList
20.special.userFunc.field = member_of
20.special.userFunc.datastructure = 44
20.special.userFunc.select.selectFields =
uid,title,nav_title,tx_templavoila_flex
20.1 = TMENU
20.1 {
NO {
doNotLinkIt = 0
stdWrap.field = title
# Remove the # from the next line if you want to see which fields are
available!
#stdWrap.data = debug:data
#typolink.parameter.field = www
ATagTitle.field = nav_title // title
allWrap = <div class="hb_link">|</div>
}
}

And the code of the userFunc is:

/* This function generates a menu out of a subset of pages for which a
certain templavoila Field list contains a certain value */

function generateFilteredMenuFromList($content,$conf) {
/**
*
* field = field that contains the list (nested)
* datastructure = templavoila datastructure (list, comma separated)
* select.selectFields = list of selected fields do you want.
*
*/
$local_cObj = t3lib_div::makeInstance('tslib_cObj'); // Local cObj.
$menuArr = array();
$subArr = array();
$lConf = $conf["userFunc."];
$value = $local_cObj->stdWrap($lConf["value"],$lConf["value."]);
$res =
$GLOBALS['TYPO3_DB']->exec_SELECTquery($lConf["select."]["selectFields"],'pages','
tx_templavoila_ds IN ( '.$lConf["datastructure"].') ORDER BY title ASC ');
//t3lib_div::debug($lConf);
//t3lib_div::debug($lConf["value."]["data"]);

if ($error = $GLOBALS['TYPO3_DB']->sql_error()) {
$GLOBALS['TT']->setTSlogMessage($error,3);
} else {
$GLOBALS['TT']->setTSlogMessage('NUMROWS:
'.$GLOBALS['TYPO3_DB']->sql_num_rows($res));
while ($row = $GLOBALS['TYPO3_DB']->sql_fetch_assoc($res)) {
$XML = t3lib_div::xml2array($row['tx_templavoila_flex']);

if (is_array($XML)) {
$subArr =
$XML['data']['sDEF']['lDEF'][$lConf['field']];

if (is_array($subArr['el'])) {
foreach ($subArr['el'] as $val) {
$fieldValue =
$val['list_member_of']['el']['field_link']['vDEF'];
if
($fieldValue==$GLOBALS["TSFE"]->id) {
unset($row['tx_templavoila_flex']);
$menuArr[] = $row;
}
}
}
}
}
}
return $menuArr;
}

Do you have PHP error reporting enabled in Install tool?

I assume you wrapped script with CDATA? Other it will produce invalid DS XML.

Please, be consistent, use only single quotes This save several milliseconds for each request.

Resource leak: recordset is not freed. You'll get lots of memory leaks in Apache/MySQL if you use persistent MySQL connections.

Sure I do. PHP warnings and errors are logged in error.log. In this
case, no error is logged.

Yes it is embedded within a CDATA.

Thanks for the suggestion. I replaced the quotes.

You are right, that was missing. I added
GLOBALS['TYPO3_DB']->sql_free_result($res);
But it still doesn't work. Up to 340 records is ok, but not more.

Could it be an error in TemplaVoila? The Admin Panel shows a correct
array for the HMENU, but no page is rendered.

TemplaVoila does not process TypoScript or menu. It only walks each field on the page and asks TYPO3 to create content for it.

So where would you look? Could it then be a bug in class.tslib_menu.php?

I have a debugger. So usually I just put a breakpoint somewhere and debug. I think tslib_menu, yes.

Can't do that, I'm working on a production server, with no debugging
tool installed. By the way, what debugger do you use? Does it work on
W**dows?

I finally found the explanation. It's a bug in the core. The
prefixLocalAnchor post processing is crashing whenever there are too
many links.

See http://bugs.typo3.org/view.php?id=6415

A working patch is available there.
