Exception in method getMembers() class ToolStrip

[aubay]

Hi,

I´m using Smart GWT LGPL Edition (2014-03-04 nightly) / GWT Framework 2.6.0 / Jetty/ Chrome 33.0.1750.146

When I try to retrieve the members of a ToolStrip

Canvas [] cMembers = toolStrip.getMembers ();

is being thrown an exception

This doesn't appear to happen on *every* call to getMembers() so we will need code that can reproduce the issue.
