Gp_menu -problem

[gtbu]

I get (tested under php5.6 , php7.4.10 and php8.0) for GetSubMenu the error : Error: Unsupported operand types: gp\Page\Edit -- int in line 122.

• A var_dump of search_level shows, that it is an object-array : ( object(gp\Page\Edit) (46) { ... } ).

• I do not understand the -1 in max(0, search_level -1) i.e. array-subtraction of an int (-1) - such max also in lower php-versions not possible ! Evtl it should be max(0, search_level, -1) ?

• Completely without the -1 gives the error : Object of class gp\Page\Edit could not be converted to int

• one remains : Object of class gp\Page could not be converted to int in: ...\include\tool\Output\Menu.php on line: 141 ($level == $search_level )

• And another problem is : echo max(0,'hello'); before PHP 8.0 will return int(0) but since PHP 8.0 it returns string("hello")!!

Up to tp5.0b2 no error comes up - first in tp5.0rc1 ( both php5.6).
Up to tp50beta2 the first sublevel of the sidemenu functions - in tp5.0rc1 it doesnt.
In both versions the menu.php is identical, and so the incoming data must be different :

A deeper look at $search_level (which is initialized with 'false' ) direct after global $page; with var_dump shows, that the strangley contained object(gp\Page\Edit) (46) { ... } is the problem :
gp\Page\Edit Object (
[draft_file:protected] => I:/Xa/xampp/htdocs/tp50rc1/data/_pages/zvDWE1u_k/draft.php
[draft_exists:protected] =>
[draft_stats:protected] => Array ( ) ....

**while in tp50b2 it contains bool(false) **
After adding $search_level=false behind $reset_level = 0; (to remove the object) the submenu disappears
Unclear from where the content *object(gp\Page* comes. Drafts appear in gp/page edit.php ( SetVars)

Perhaps has Joshua an idea (the code exists already in gpeasy 4.4.

P.S. After long nights here a workaround : Add $search_level=0; before $reset_level = 0; (empty line 119)

• with 0 You get the full submenu with the other lower levels
• with 1 You get only the first sub-level
• with 2 You get only the second sub-level
  This should be worth to reprogram it so far, that < ? php GetSubMenu() > can be used with (,,1...3).
