Just curious if anyone else has come across the treeGrid parents not collapsing ? I am having this problem with both xml and json. I see it works in the demo so there must be a trick I am missing.

* Using the latest version 3.5.3

* checked the docs to no avail

* Firefox 3.0.14

* Mac OSX 10.5.8

HTML

 <html><head><link rel="stylesheet" type="text/css" media="screen" href="css/sunny/jquery-ui-1.7.2.custom.css">
 <link rel="stylesheet" type="text/css" media="screen" href="ui.jqgrid.css"> 
 <script type="text/javascript" src="jquery-1.3.2.min.js"></script>
 <script type="text/javascript" src="grid.locale-en.js"></script>
 <script type="text/javascript" src="jquery.jqGrid.min.js"></script>
 <script type="text/javascript" src="xml.js"></script></head>
 <body><table id="list2" class="scroll" cellpadding="0" cellspacing="0"></table>
 <div id="pager2" class="scroll" style="text-align:center;"></div></body></html>

xml.js code:

$(document).ready(function(){
    jQuery(”#list2″).jqGrid({
        url: 'tree.xml',
        treedatatype: “xml”,
        mtype: “POST”,
        colNames: ["THING","id"],
        colModel: [{name: 'thing', index: 'thing', width: 220, hidden: false},
                  {name: 'id', index: 'id', width: 120, hidden:false, key:true}],
        height: 300,
        width: 300,
        pager: jQuery(”#page2″),
        imgpath: 'css/sunny/images',
        treeGrid: true,
        ExpandColumn: 'thing',
        caption: 'My Things!',
    })
});

Results from initial call to tree.xml:

<rows>
<total>1</total>
<page>1</page>
<records>1</records>
<row>
<cell>Jon Henry</cell>
<cell>0</cell>
<cell>0</cell>
<cell>0</cell>
<cell>0</cell>
</row>
<row>
<cell>Margret Woot</cell>
<cell>3</cell>
<cell>0</cell>
<cell>0</cell>
<cell>0</cell>
</row>
</rows>

Results from post call upon opening first parent:

<rows>
<total>1</total>
<page>1</page>
<records>1</records>
<row>
<cell>Alex Henry</cell>
<cell>1</cell>
<cell>1</cell>
<cell>0</cell>
<cell>1</cell>
</row>
<row>
<cell>Angela Henry</cell>
<cell>2</cell>
<cell>1</cell>
<cell>0</cell>
<cell>1</cell>
</row>
</rows>

No POSTS are being returned to the server upon clicking the collapse button.

=============

As a side note treedatatype: “json”, doesn't work.

Thanks in advance for any guidance.

Never mind about the collapsing

Little does one easily know:

* The first parents left_field must be = to it's id and 0 (unless set otherwise).

* The first parent right_field must be = this parent last child id + 1

* The first child left_field must be = the parent id + 1

* The first child right_field must be = its' left field + 1

* Each progressive childs left_field must = the previous childs right_field

* Each progressive childs right_field must = this childs left_field + 1

* Each progressive parents left_field must = the previous Parents last childs' left_field + 1

* Each progressive parents right_field must = its' left_field + 1

As an additional note the level_field is for “indentation”… 0 = baseline, 1 indent = 1 space, 2 = indent 2 spaces…

The plugin is great, but the documentation is horrific.
