Mozilla problem

[James]

Now I've managed to hack around IE's most obvious problems, I'm trying
to get all the features working properly on Mozilla as well.
Unfortunately, a variable (declared in a script tag outside a function,
so it should be global) is somehow losing its definition: an alert()
elsewhere in that script has a value, but later (both in other chunks
of javascript and from the javascript console) it adopts a value of
null. Any pointers?

Any URL or simple example?

This groups FAQ would be the first obvious place. The people here are
not mind-readers nor can we read/diagnose code that is unseen.

Post a URL to the page that has the problem with it.

Check that you haven't declared it somewhere else also.

Check that if you've used it in a test somewhere (if, for, etc.) that
the evaluation isn't changing its value.

Post the code or a link.

Keep moving your 'alert' down the script until it fails, then you're
close...

Thanks Rob - most helpful reply I've seen in a while. I haven't
duplicated the declaration or changed its value anywhere, and my code
is executing as expected - it turned out to be a Heisenbug of sorts,
since the Mozilla Javascript console wasn't behaving as I expected
either.

The root problem I was trying to tackle remains - I can't call an
applet's methods in Mozilla, only in IE - but it looks like the thread
at http://forum.java.sun.com/thread.jsp...9896&tstart=60 has
the same situation and solution...

This is the same type of trouble I'm having as reported in the thread
"Tooltips position at prior-set location in Firefox." In my case, the
variable is returning its PREVIOUS value at the time that it is passed into
code that controls the location of my tooltip. If the problem was merely
that the variable becomes corrupted or a global/local aspect is involved, it
should affect the IE results, too, which it doesn't.
