When we add custom ribbon to SharePoint 2010, it may display well in IE but not in Chrome and Safari. The sample xml is below like this:
<Tab Id=""Ribbon.CustomTab"" Description="""" Sequence=""4000"" Title=""测试Ribbon"">
<Scaling Id=""Ribbon.CustomTab.Scaling"">
<MaxSize Id=""Ribbon.CustomTab.Scaling.Custom.MaxSize"" Sequence=""10"" Size=""LargeLarge""
GroupId=""Ribbon.CustomTab.Group""/>
<Scale Id=""Ribbon.CustomTab.Scaling.Custom.Popup"" Sequence=""20"" Size=""Popup""
GroupId=""Ribbon.CustomTab.Group""/>
</Scaling>
<Groups Id=""Ribbon.CustomTab.Groups"">
<Group Id=""Ribbon.CustomTab.Group"" Sequence=""30"" Title="""" Description=""""
Template=""Ribbon.Templates.Flexible2"">
<Controls Id=""Ribbon.CustomTab.Controls"">
<Button Id=""Ribbon.CustomTab.Button"" Image32by32=""/_layouts/2052/images/formatmap32x32.png""
Image32by32Top=""-320"" Image32by32Left=""-64"" Command=""CustomCommand"" Description="""" LabelText=""Click Me"" Sequence=""10""
TemplateAlias=""o1"" ToolTipTitle=""Test"" ToolTipDescription=""Test""/>
</Controls>
</Group>
</Groups>
</Tab>
We may cost a long time but can't find the reason. Why SP 2010 own ribbon works well in Chrome and Safari?
The reason may be a little disappointing for the Group tag with Title attribute null...
When we set the Title attribute, it works well.
