SST, VA Assist and Trailblazer don't play nicely together

[jtuchel]

Hi there,

When you load SST, there are several things going on that I still need to get used to (euphemism ).

One thing that I don't fully understand is that SST always wants to load Trailblazer. I don't want to use Trailblazer and since I only want to do simple HTTP Client/Server-stuff with SST, I have no idea why I should use it. It's not that hard to switch back to normal Browsers, so I can live with it.
What really is annoying that it can cause some weird debuggers popping up in conjunction with VA Assist (I believe there is this relation).

Try the following sequence (I'm using VAST 7.5.2 on Win XP):

1. Copy a newimage to your image directory
2. start this clean image
3. load the config map z.ST: Server, SST
4. Try to open the preferences window (Transcript->Options->Open Preferences Window...)
5. Welcome the debugger:

Just a small addition: if you switch Trailblazer off before opening the preferences window, everything is fine.

Hello,

After loading the SST feature, select 'use standard browsers' from the tools menu on the transcript. Save your image and use that as a base. I actually have three images set up, a DB image, web services image, and a clean image (no features loaded).

With each of the images, I do not have development apps loaded.

Trailblazer is something normally used with server workbench and loading SST loads server workbench.

taylor,

thanks for the info. That's what I've found out as well. I'd consider such behaviour a bug however.

The question if Trailblazer is helpful or not has to be answered by people who use it. But VA Assist as well as Trailblazer are part of the supported product and they should just work without such workarounds.

Kind regards

Joachim

Our plan is to get rid of the Trailblazer or make it an unsupported goodie (which is what it really is now).

[jtuchel]

I like that plan, I never got warm with Trailblazer

I don't know. It had one useful feature, at any rate. That is the ability to display the graphical history of editions.

There is no reason that functionality couldn't migrate to the regular browsers.

Actually I really like the "trails" in trailblazer. When doing certain kinds of research they are a great way of keeping track of how you got where you are and walking through various code paths.

BUT!!, I almost never use Trailblazer because it is different in ways that it doesn't need to be. Why are all the pop-up menus different from the standard browsers? Why do I have to choose between one set of browsers and the other? Because of this I never got comfortable in it.

I believe if it used "standard" pop-up menus instead of completely different nomenclature, and "Browse in Trailblazer" were a menu addition in the standard browsers, I would use it for 30% or more of my browsing.

So, personally, I'd rather see it "fixed" than turned into a Goodie. But, of course, as Eric notes, it already is pretty much an unsupported goodie, so my wishes are probably moot. Unless, of course, I want to spend the time to make it work the way I wish it did.
