The code below throws OverflowException when trying to expand ShapeNode:

[code]
MindFusion.Diagramming.Layout.SpringLayout _diagramLayout;

private void Form1_Load ( object sender, EventArgs e )
{
_diagramLayout = new MindFusion.Diagramming.Layout.SpringLayout ( 100, 15, true, true );
_diagramLayout.MultipleGraphsPlacement = MindFusion.Diagramming.Layout.MultipleGraphsPlacement.Horizontal;

ShapeNode center = createDomainShape ( "center" );

}

private ShapeNode createDomainShape ( string name )
{
ShapeNode b = view2D.Diagram.Factory.CreateShapeNode ( 1F, 1F, 10F, 8F );
b.Expandable = true;
b.Expanded = false;

b.EnableStyledText = true;
b.TextFormat.FormatFlags = StringFormatFlags.NoWrap;
b.Text = String.Format ( "<b>{0}</b>", name );

b.ResizeToFitText ( FitSize.KeepHeight );

return b;

}

private void _diagram_ExpandButtonClicked ( object sender, NodeEventArgs e )
{
for ( int i = 0; i < 19; i++ )
{
ShapeNode nested = createDomainShape ( String.Format ( "Nested #{0}", i ) );
DiagramLink dlink = _diagram.Factory.CreateDiagramLink ( e.Node, nested );
}

if ( _diagramLayout != null && _diagram.Nodes.Count > 0 )
_diagramLayout.Arrange ( _diagram );
}
[/code]

[b]To reproduce the error please to the following:[/b]
- create new WinForms project
- open 'Form1'
- paste the code above to 'Form1.cs' file
- assign handler 'Form1_Load ' to 'Form.OnLoad' event
- put on form Mindfusion.DiagramView
- set ExpandButtonAction = RaiseEvents
- assign handler '_diagram_ExpandButtonClicked' to 'Diagram.ExpandButtonClicked' event
- run application
- expand node 'Center'

[b]Mindfusion's assemblies version:[/b]
MindFusion.Diagramming                   5.2.1.22983
MindFusion.Diagramming.WinForms   5.2.1.22984
MindFusion.Common                          1.2.3368.20041



[b]Note[/b]
If code below is commented then all is working expectedly:
[code]b.EnableStyledText = true;
b.TextFormat.FormatFlags = StringFormatFlags.NoWrap;[/code]

Also if count of created nested nodes less than 15 then exception is not thrown too.

Please let me know if you unable reproduce the error, I'll provide more details.

Thanks,

Hi Stoyan,

This fix works great!

Thank you for the quick update.

Provided by the link fix contains trial libraries, how can I get licensed libraries with included fix( as now I already have licensed libraries)?


Thanks,
Alex
