Re: [ptp-dev] Need method to post error messages in parallel tab

["Randy M. Roberts" <rsqrd@xxxxxxxx>]

Dave,

It's working for me.  You may have missed a crucial piece of code that
makes it work...

Take a look at the example in
org.eclipse.ptp.orte.ui.rmLaunchConfiguration.ORTERMLaunchConfigurationDynamicTab.java

Lines 103-111 add a ModifyListener to the text widget where one enters
the number of process.  As one types into the widget this listener's
modifyText(e) method is called.  This method first sets the
numProcsString string, and then calls fireContentsChanged(), which is
defined in AbstractRMLaunchConfigurationDynamicTab.  The
updateLaunchConfigurationDialog() method will be called, which
leads to ORTE...DynamicTab's isValid() method being called.  The
isValid() method checks the validity of the numProcsString, and
sets the error message.

I've left out some intermediate steps.

Are you doing something like this and still not seeing the
error messages?
