debugging jumpstart in Eclipse (missing line numbers)
I have jumpstart running in Eclipse as a java app, and it works with the
exception of the login. When I log in as admin, I get a null pointer
exception:
jumpstart.web.components.theapp.NavBar.isSecurityTabActive(NavBar.java:18)
I set a break point in eclipse on line 18 in NavBar.java, and when I run it
in Eclipse, Eclipse tells me that it cannot install a a break point because
the class files were compiled without line numbers.
So I enabled the line numbers in the Eclipse environment, but that didn't
help.
I'm unfamiliar with many of the tools used in this project, and can't figure
out how the collapser gets invoked during app launch, much less how to
ensure line numbers are included!
Any idea how can I enable this?

I've released 5.4.15 with the fix.
Please let me know whether the "Debugging" section I've just added to the Tips page answers your other questions.

Re: debugging jumpstart in Eclipse (missing line numbers)
Posted by Geoff Callender <ge...@gmail.com>.
The fix is to replace the parameter declarations in NavBar.java with these:
@Parameter
private String tab = "";
@Parameter
private String subTab = "";
and in Layout.java with these:
@Parameter
private String tab = "";
@Parameter
private String subTab = "";
@Parameter
private String title = "";
I'll release 5.4.15 with the fix shortly.
BTW, I've learnt something. By my reading of the Parameter javadoc (http://tapestry.apache.org/tapestry5.2-dev/apidocs/org/apache/tapestry5/annotations/Parameter.html), I thought these 3 declarations should be equivalent:
@Parameter
private String tab;
@Parameter(value = "")
private String tab;
@Parameter
private String tab = "";
but they are not: if the parameter is not bound, then in the first two its value will be null, and in the third one it will be "".
I've raised https://issues.apache.org/jira/browse/TAP5-1668 .
I'll have a look at your debugging questions soon.

Re: debugging jumpstart in Eclipse (missing line numbers)
Posted by George Ludwig <ge...@gmail.com>.
Geoff,
One more thing, I changed NavBar.java to add a check if the tab is null:
public boolean isSecurityTabActive() {
if(tab==null)
return false;
return tab.equals("Security");
}
Now the app appears to work, but I sure wish I understood better how
the tab param should have been passed in the first place!

Re: debugging jumpstart in Eclipse (missing line numbers)
Posted by George Ludwig <ge...@gmail.com>.
Geoff,
I'm running jumpstart 5.4.14 in Eclipse 3.7 on OSX 10.5.8.
However, as Jonathan mentioned if I ignore the error, the debugger
takes me to the correct line in NavBar.java But all I can see is that
the tab parameter is null. :)
I can't see the source in any of the tapestry jars, so that's about as
far as I can go in the debugger. Is there a way to use ant to download
the sources and make Eclipse aware of them? Is it even worth the
trouble?
It's been a long time since I used Ant...
It just occurred to me to try this on my machine at home, which is a
Vista box. Will let you know if it changes anything.
Best,
George

What version of JumpStart are you running and what OS are you on? I'll try to have a look in the next 24 hours at what's gone awry.

I hit this as well today.
Strangely, I said to ignore it, and after the usual prompting for a location
to find source files, debugging worked just fine.
