[Chameleon] Problem with CWC2OnLoadFunction...

[Aaron Racicot]

Jason,

I have been going through the chameleon code to try and locate where I am
having problems.  I have taken your advise and gone back to the downloaded
demo from the MapTools web site.  

I have started to systematically walk through the code to try to debug my
problem.  What I have come up with is that in the UIManager.php file I am
getting a JS runtime error at the following piece of code:

+++++++++++++ Start code +++++++++++++++++++++++
function DrawPublish()
{

    //get javascript code from widgets
    $this->ProcessWidgetIncludes();

    // Debug Added by Aaron Racicot
    echo "PRIORITY_MAXIMUM= ".PRIORITY_MAXIMUM."<br>";
    echo "PRIORITY_MINIMUM= ".PRIORITY_MINIMUM."<br>";

    //process widgets into template
    for ($i=PRIORITY_MAXIMUM; $i>=PRIORITY_MINIMUM; $i--)
    {
      foreach( $this->manPriorities[$i] as $nWidgetIndex )
      {
	  // Debug Added by Aaron Racicot
        echo "Loop i= ".$i."   nWidgetIndex= ".$nWidgetIndex."<br>";

        $oWidget =& $this->maoWidgets[$nWidgetIndex];
        $this->oCWCParser->SetElement( $nWidgetIndex,
$oWidget->DrawPublish() );
      }
    }
    $this->oCWCParser->ProcessElements();
++++++++++++++ End Code +++++++++++++++++++++++++

I added some debug output to show the looping indexes and widget index and I
get the following:

PRIORITY_MAXIMUM= 5
PRIORITY_MINIMUM= 0
Loop i= 4 nWidgetIndex= 12
Loop i= 3 nWidgetIndex= 17
Loop i= 2 nWidgetIndex= 0
Loop i= 2 nWidgetIndex= 1
Loop i= 2 nWidgetIndex= 2
Loop i= 2 nWidgetIndex= 3
Loop i= 2 nWidgetIndex= 4
Loop i= 2 nWidgetIndex= 5
Loop i= 2 nWidgetIndex= 9
Loop i= 2 nWidgetIndex= 13
Loop i= 2 nWidgetIndex= 14
Loop i= 2 nWidgetIndex= 15
Loop i= 2 nWidgetIndex= 16
Loop i= 2 nWidgetIndex= 18
Loop i= 2 nWidgetIndex= 19

At this point I get an error which is from the CWC2OnLoadFunction never
getting created just after this in the DrawPublish function.  The
interesting thing is that the index $i never reaches 1 or 0.  

Does this ring a bell for you?  I am very confused why my installation seems
to have this problem (which now does not seem to be path or permissions
related).  Thanks

Aaron

Hi Aaron,

Have you tried downloading and installing (ie, unzipping) the Chameleon 
sample application from Maptools.org 
(http://maptools.org/chameleon/index.phtml?page=downloads.html)?  It's 
located at the bottom of the page.  At the very least it will give you 
an indication of the files required for an application as well as a 
suggested directory structure. 

Generally speaking a Chameleon application will reside outside your core 
Chameleon installation.

Best Regards,
Jason
