nested control problem

hey, all.
i am working on a project that needs to do some nested control stuff.

Site Tree
+ product holder (ProductHolderType)
-Product A (ProductPage Type)
-Product B (ProductPage Type)
-term and condition (Page Type)

The outcome i wanna achieve is on my ProductHolder, ProductA,B and Term and condition Page show side bar for secondary-level navigation.

i created a sideNav.ss in the include file.

   <% control Menu(2) %>

             <% if LinkOrSection = section %>
                <% if Children %>
                  <h4>
                     $MenuTitle.XML
                   </h4>
                  <ul class="sub">
                     <li>
                        <ul class="roundWhite">
                           <% control Children %>
                              <li><a href="$Link" title="Go to the $Title.XML page" class="$LinkingMode levelb">$MenuTitle.XML</a></li>
                           <% end_control %>
                        </ul>
                     </li>
                  </ul>
                 <% end_if %>
            <% end_if %>
         </li>
   <% end_control %>

The ProductHolder, and ProductPage type works fine.

Since i have already got lots of different page types, thought it will be neasty for creating a new Page type for using the side bar there.
So i wanna achieve If the normal Page under the ProductHolder -> show sidebar. otherwise dont show.

i did something like    <% control Parent %>
         
         <% if ClassName = ProductHolder %>

         <% include SideNav %>
         
         <% end_if %>
         
         <% end_control %>

i dont why the code in the SideNav.ss cannot be executed. maybe they nested control there?!

Another alternative way:
try to use php code logic to do the if statement and renderwith the template in the include file.
was doing someting like:

public function includeSideNav(){
      Debug::show($this->Parent()->ClassName);
      if($this->Parent()->ClassName=="ProductHolder")
         {
            //display the outcomes
            return Director::$this->renderWith("Includes/SideNav.ss");
            }
      }

But seems doesnt work. error message[stat failed for Includes/SideNav.ss]

Anyone can help :)
Thanks in advanced

Hi SSAdmin

The last section is erroring becuase you are calling the following wrong
return Director::$this->renderWith("Includes/SideNav.ss");
should be
return Director::$this->renderWith(array("SideNav"));

That should resolve your stat problem, let me know how you go

As for your orginal idea i can not see where it is going wrong, have tried using the ?showtemplate=1 to see what is going on?

hey, hive.net.au

Thanks for your timely reply.

i have changed the return Director::$this->renderWith("Includes/SideNav.ss") to Director::$this->renderWith(array("SideNav"));
It works perfectly.

I was still confused how the frist approach doesnt show anything.
So i did run ?templeshow=1;

The view code is listed following:
29       <div class="aside">
30          
31       
32 SSVIEWER;
33 array_push($itemStack, $item); if($loop = $item->obj("Parent")) foreach($loop as $key => $item) { ;
34 $val .= <<<SSVIEWER
35
36
37
38 SSVIEWER;
39 if($item->XML_val("ClassName",null,true) == "ProductHolder") { ;
40 $val .= <<<SSVIEWER
41
42
43 <!-- include C:/wamp/www/clicknz/themes/clicknz/templates/Includes/SideNav.ss -->

45    
46 SSVIEWER;
47 array_push($itemStack, $item); if($loop = $item->obj("Menu", array("2"))) foreach($loop as $key => $item) { ;
48 $val .= <<<SSVIEWER
49
50
51              
52 SSVIEWER;
53 if($item->XML_val("LinkOrSection",null,true) == "section") { ;
54 $val .= <<<SSVIEWER

56                 
57 SSVIEWER;
58 if($item->hasValue("Children")) { ;
59 $val .= <<<SSVIEWER

93                            
94 SSVIEWER;
95 } $item = array_pop($itemStack); ;
96 $val .= <<<SSVIEWER

98                         </ul>
99                      </li>
100                   </ul>
101                 
102 SSVIEWER;
103 } ;
104 $val .= <<<SSVIEWER
105
106             
107 SSVIEWER;
108 } ;
109 $val .= <<<SSVIEWER
110

112    
113 SSVIEWER;
114 } $item = array_pop($itemStack); ;
115 $val .= <<<SSVIEWER

117 <!-- end include C:/wamp/www/clicknz/themes/clicknz/templates/Includes/SideNav.ss -->
118
119
120 SSVIEWER;
121 } ;
122 $val .= <<<SSVIEWER
123
124
125
126 SSVIEWER;
127 } $item = array_pop($itemStack); ;
128 $val .= <<<SSVIEWER
129
130
131 </div>   <!--close aside-->

Seems the loop has been executed to me. but why nothing displayed afterwards. The Term conditions and ProductA are in the same level, which means if it can be dispalyed on ProductA page should be display on normal page as well using same inlcude file( SideNav.ss ). Any ideas?

Anyway.thanks for your help hive.net.au :P
