Re: [ptp-dev] Fw: Questions about JAXB parser

I'll take a look at the spinner class
to see if that does what I want. 

I have at least one case where the value
can be numeric or one of a set of strings where I expect to use an editable
dropdown/combo box and need numeric validation. I also have some values
where the PE implementation accepts values like 1M instead of 1000000 and
I'm thinking I want to follow that pattern, so would need validation there.

I'm also not sure what happens with
a spinner if I enter out of range or non-numeric data. If it just beeps
at me I think that's confusing since it doesn't tell me what's wrong, whether
I'm entering invalid data or if the keyboard focus is somewhere where it
shouldn't be.

The command actually does work and write
to /tmp/ptp_out. I can implement a shell script which echoes environment
variables and invoke that in place of the echo command to see if environment
variables are being passed across in the process environment.

One other question. 

Is there a stdout or stderr parser implementation
in your code that simply echoes the stdout/stderr to the console view in
Eclipse? I'm using shell redirection as an alternative to that now since
I'm taking this one step at a time.

No need for you to be on the call this
morning unless you choose to. It sounds like I'm not too far off track
with what I'm doing, so I can make progress until you are back at work.

Hi Dave,

I'm taking a couple of days away from work, but I have been checking my
email.  I can respond initially to your questions but ultimately we'll
need to revisit them.

First, the validator.  This may be a bug; it should work.  However,
in the case of simple numerical validation, why not just use a Spinner
widget for that value and forget validation in the attribute? (of course,
if this is a bug, I will fix it).

Second, environment variables defined inside a command are precisely that;
they are not defined in the scope of the resource manager configuration.
 So you will not get it as a substitution into the actual command
that is issued; however, I would have thought the echo would get the actual
environment variable from the process environment.  Two things:

a) as it stands, the value of the environment variable should not have
the ${...} tag, this is added under the covers; try getting rid of that
and see if it works.  Your usage, however, has suggested to me that
it actually is better to do what you are doing, because the value may just
be a constant, not a reference to a property or attribute (I had overlooked
this), in which case, wrapping it in ${ptp_rm:...#value} would fail.  So
I will eventually change the environment variable to work the way you have
it here.

b) I am actually surprised this command runs at all. Do you actually get
ptp_out?  I didn't think the RemoteProcessBuilder allowed explicit
shell I/O redirection. 

I can be on the call today if you want to discuss this more.  Let
me know.
