hi ! I 'm french so sorry for my approximative english

I deteced a error in treegrid , i receive the error "too much recursion in firefox" or "out of memory in IE". I resolve this by add a condition in the function collpaseRow in the treegrid object :

collapseRow: function(record) {
            this.each(function() {
                var $t = this;
                if (!$t.grid || !$t.p.treeGrid) { return; }
                var childern = $($t).getNodeChildren(record);
                $(childern).each(function(i) {
                $(this).css("display", "none");
                    if(this.expanded)
                    $($t).collapseRow(this);
                });
            });
        }

Bye

I too am suffering with the 'too much recursion' problem with Firefox when I collapse certain branches of a deep tree grid. IE8 gives an 'Out of Memory' error. Small branches can be closed successfully.

I tried the above fix with jqGrid 3.5.3 but no joy so I then tried jqGrid 3.6beta and I noted that the above fix had been included but with additional changes to the function. But alas the error still occurs.

I'm new to jquery & even newer to jqgrid as this is my first foray with it so perhaps I am not using it correctly.

The grid at http://familytrees.genopro.com.....ntTree.htm exhibits the problem.

I tried to diagnose the problem using FireBug without success. I suspect it is a problem with getNodeChildren function

Any help appreciated. Smile

Hello,

I found your problem and the cause.

In your xml data you have equal id – example

The name: Sirius Black ( b. 7 Aug 1959 d. Jun 1996)

once you have

<row>
<cell>ind00009</cell>
<cell>Sirius Black ( b. 7 Aug 1959 d. Jun 1996)</cell>
<cell>15</cell>
<cell>fam00007Children</cell>
<cell>true</cell>
<cell>true</cell>
</row>

And the same second time

<row>
<cell>ind00009</cell>
<cell>Sirius Black ( b. 7 Aug 1959 d. Jun 1996)</cell>
<cell>15</cell>
<cell>fam00007Children</cell>
<cell>true</cell>
<cell>true</cell>
</row>

This coause infine loop of the recursion.

In order to correct – EVERY ITEM in the xml SHOULD HAVE UNIQUIE ID and correct setting of parent node.

In terms of jqGrid this is not valid xml tree data.

If you notice you can not select some nodes in the tree, because of the reason listed above

Regards

Tony

Brilliant! Thanks for finding that Tony and hands up Embarassed it was my data that was at fault. In this particular data set there is a marriage between two second cousins and hence the family occurs twice, once in each branch of the family. I'll have to find a way to differentiate the IDs.

Thank you for a great plugin and the support is 1st class too Cool
