ExtJS rowexpander - Collapse-Icon on render

[matscher]

I use the rowexpander plugin in a grid. The problem is that after rendering the plugin shows the collapse-icon at each row instead of the expand-icon.

//RowExpander
{
   ptype: 'rowexpander',
   rowBodyTpl : [
      '<p><b>Project name:</b> {project_name}</p><br>',
      '<p><b>Summary:</b> {desc}</p>'
   ],
}

If the collapse-icon is clicked it changes to the expand-icon and from there it works fine.
What's the reason for this behavior and how can I solve it?
regards!

Can I get the exact version of ExtJS4 that you are using?
Are you using the latest release?

Please check 4.1 with your code before begin to research this as a open bug.
