Executing a command twice fails [message #769583]

Hi all,

It´s my first time working with org.eclipse.ui.menus menuContribution and
org.eclipse.ui.commands
to cause a wizard page to be executed. A Handler class set as defaultHandler
is responsible for executing the
command mentioned above. My implementation works for the first execution.
But executing it twice
it fails with the following exeception:

org.eclipse.core.commands.NotHandledException: There is no handler to
execute for command

Any advice on what the problem is?
Thanks in advance.

How is your handler contributed? Where is the menu item or tool item you are executing the command from the second time?

Never mind, issue resolved. I made an implementation mistake which is rather
specific to my problem domain, would rather not go into further details
about it.
