Re: [ptp-dev] Questions about remote support

Greg
I just updated from head a few minutes ago and now I'm getting a null
pointer exception (see bottom of this email) when I try to create a new
resource manager. This happens when I open the resource manager wizard,
click PE from the list and click next. This worked correctly this morning.
If I updated while you were in the middle of commits, that's fine, just
let me know to try again later.
Also, the way my parallel tab works, I have a text entry field with a
ModifyListener registered, and an accompanying Text field that gets filled
in with a path name. This gets filled in either by the user typing in a
path name or by my code as a result of the user selecting a file from the
file selector, in which case I get the IPath object returned by calling
browseFile, call toString() on that object and then fill in the text field
with that value.
I don't attempt to validate the pathname until the ModifyListener
registered on the text field gets called, which occurs either when the
user types in the field or when my code fills in the field using the
pathname obtained from the IPath object. If the user has typed in a field,
I don't see any way to validate that pathname, since I only know the
pathname and the remote connection at that point (I don't have an IPath
object). If I do have an IPath object, because the user clicked the
browse button, then is the intent I call getResource() to get the
associated IRemoteResource, then validate using that object?
Thanks

Ugh, yes I see the problem. I'll fix this asap.

You should never need to create instances of the file manager
implementation directly. Always use the IRemote* interfaces. Assuming
you've subclassed AbstractRemoteResourceManagerConfiguration, use the
getRemoteServicesId() method on your configuration to get the name of
the remote service provider that has been selected. Then use
PTPRemotePlugin.getRemoteServices() to get the IRemoteServices
object. You then get the file manager by calling
IRemoteServices.getFileManager().
I've committed some changes to the way this works, as well as added
support for direct file manipulation. I'm just documenting it now.
