"Loading Mapbuilder program" runs into mapbuilder javascript errors

It looks like I've got a configuration with mapbuilder's JavaScript. From FF's error log:

Error: this.node has no properties.
Source File: ... all/modules/mapbuilder/mapbuilder-src/lib/widget/MapContainerBase.js

So, the good news is, the mapbuilder is finding the files. But it's not understanding them.

1. My $base_url is set in settings.php

2. Per the main Community Mapbuilder site, text/xml is a mime type:

# less mime.types |grep xml
application/xhtml+xml xhtml xht
application/xslt+xml xslt
application/xml xml xsl
application/xml-dtd dtd
application/xml-external-parsed-entity
text/xml
text/xml-external-parsed-entity

That's all I know to look for. What am I doing wrong?

PHP 5.2.1, curl and DOM installed, Drupal 5.1

openwereld:

I have caching enabled under Drupal 5.1 (not "aggressive," but normal).

And I really hate to rip out Drupal 4.1 and revert to 4.7.*

It sounds like I don't need to rip out and re-install Mapbuilder -- since the JS files are being understood. (That is, they wouldn't be throwing errors if they weren't being read).

Thanks for the ideas on a JavaScript patch but I have some questions:

1. Are you using the 1.0.1 stable release for the patch and for your testing or (as the config.xml file suggests) the 1.5 alpha? (I used 1.0.1)

2. How did you choose those two files (sarissa and extent) to load? From the errors that were thrown on your installation?

3. Do you have any other suggestions for me to test that my installation is installed and set up properly? Not to trash the documentation again, but for a lot of this, I was hoping I guessed right...

I'll try this and post my results...

My results:

I made the JavaScript change ("// ADDITION: make sure that Extent.js is loaded in time") and just got new errors of stuff that's not defined.

I'm going to rip out my installation and reinstall using the 1.5 alpha mapbuilder (since I surmise from your config.xml file, openwerel, that you are using that).

openwerel:

Javascript errors with Mapbuilder are often very difficult to solve. Sometimes you get javascript errors because the html doesn't contain the html elements which are referred to in the map config document

Huh? Couldn't you use XML schema to make sure undefine elements don't happen?

One more question, openwereld:
You write:

the Extent.js file was the last file to load (as shown in the generated page source)

Could you include the generated page source, so I can see what the page ought to have? Thanks.

Again, complete failure, after re-installing everything with the 1.0.1 mapbuilder library, and the suggested patch.

1. Submitted config node with demo context node (13) as per http://drupal.org/node/112157

2. Submitted blog node with mapbuilder input format on and the following HTML as per README.txt

<map>mapbuilder/config/15</map>

3. All I get is the animated "Loading mapbuilder" gif and the following error:

Error: this.node has no properties
Source File: http://www.universalpantograph.com/sites/all/modules/mapbuilder/mapbuilder-src/lib/widget/MapContainerBase.js
Line: 85

The settings:

1. config.xml:

<defaultModelUrl>/public_html/sites/all/modules/mapbuilder/demo/demisWorldMap.xml</defaultModelUrl>
<skinDir>/public_html/sites/all/modules/mapbuilder/mapbuilder-src/lib/skin/default</skinDir>

(The skinDir doesn't include "en," so I assume that's added automagically so the system can find widgetText.xml.)

2. admin/settings/mapbuilder:

Base: sites/all/modules/mapbuilder/mapbuilder-src/
Skin: sites/all/modules/mapbuilder/mapbuilder-src/lib/skin/default/

3. mapbuilder.module
<?PHP
// the path for contrib modules changes in drupal 5
if (!defined("VERSION") || floatval(VERSION) < 5) {
define("DEFAULT_MAPBUILDER_PATH", 'modules/mapbuilder/mapbuilder-src/');
} else {
define("DEFAULT_MAPBUILDER_PATH", 'sites/all/modules/mapbuilder/mapbuilder-src/');
}
?>

4. PHP5 with curl and xml. Drupal 5.1. FF 2.0.0.1. Here's the relevant HTML from the page build:

<script type="text/javascript">
  // URL of Mapbuilder configuration file.
  var mbConfigUrl="/mapbuilder/config/15";
  var baseDir="/sites/all/modules/mapbuilder/mapbuilder-src/lib";
  var language="en";
  
  // ruler?
</script>

<script type="text/javascript" src="/misc/jquery.js"></script>

<script type="text/javascript" src="/misc/drupal.js"></script>
<script type="text/javascript" src="/misc/textarea.js"></script>
<script type="text/javascript" src="/sites/all/modules/mapbuilder/mapbuilder-src/lib/Mapbuilder.js"></script>
<script type="text/javascript">
  function initOnLoad()
  {
    //alert( "init on load" );
  }

  function mapbuilderInitOnLoad()
  {
      mbDoLoad( initOnLoad );
  }

  if( Drupal.jsEnabled )
  {
    $(document).ready( mapbuilderInitOnLoad );
  }
</script>

Thanks for any help you can give.

Again, failure with FF 2.0.0.1. I made the change to the JavaScript. Here is what the HTML for the map node looks like:

<!-- begin content -->

<div id="node-14" class="node"><span class="submitted">Mon, 02/26/2007 - 02:40 &Ntilde; <a href="/user/xxx" title="View user profile.">xxx</a></span> 

<div class="content">
<div id="mainButtonBar_15"></div>

<div id="mainMapPane_15" class="c1"><noscript>This page requires Javascript to be enabled</noscript></div>
<div id="loading_15">
<p>Loading Mapbuilder program<br>
<br>
 <img alt="" src="/sites/all/modules/mapbuilder/mapbuilder-src/lib/skin/default/images/Loading.gif"></p>
</div>

<div id="legend_15"></div>

<div id="featureInfo"></div>

<p>1 2 3</p>
</div>

<div class="clear-block clear">
<ul class="links inline">
<li class="first blog_usernames_blog">
<a href="/blog/xxx" title="Read xxx's latest blog entries." class= "blog_usernames_blog">xxx's blog</a></li>
<li class="last comment_add"><a href="/comment/reply/14#comment_form" title="Share your thoughts and opinions related to this posting."
class="comment_add">Add new comment</a></li>
</ul>
</div>
</div>

<div id="comments"></div>

<!-- end content -->

There is no DIV with id=locatorContainer.

And here is the block for mapbuilder_generate_config:

function mapbuilder_generate_config( $nid = 0, $arg = '', $vid = NULL ) {
  if ($nid == 'add') {
    // used during preview
    $node = new stdClass;
    $node->nid = $node->vid = 0;
    // use modelUrl from $_SESSION
    $node->modelUrl = $_SESSION['modelUrl'];
    unset($_SESSION['modelUrl']);
    //echo var_export($_POST,true);
    //return;
  }
  else {
    $node = node_load( $nid, $arg == 'revisions' && is_numeric($vid) ? $vid : NULL );
    if ($node === false || $node->type != 'mapconfig') {
      // todo: error message
      drupal_set_header( 'Content-Type: text/plain' );
      echo var_export($node,true);
      return;
    }
  }

What is the line I am supposed to patch, and how do I patch it?

Again, here is the error I am still getting in FF -- it's the same.

Error: this.node has no properties
Source File: http://www.universalpantograph.com/sites/all/modules/mapbuilder/mapbuilder-src/lib/widget/MapContainerBase.js
Line: 85

I do get HTML errors, but not the ones that you mention.

http://validator.w3.org/check?verbose=1&uri=http%3A%2F%2Fwww.universalpa...

Could you point me to a working installation, or post the HTML? Maybe that will help me find out what's going on. I keep thinking there's some JS config issue I'm missing (baseDir) but Drupal JS is supposed to work out of the box...

Good luck with PHP4 XML functions; they're a mess, as I'm sure you're finding out...

Yes, this fix worked for me. Thank you. (I revised the installation and testing documentation that I wrote accordingly.)
