206529 - Javascript can't run Java instance method via LiveConnect during onLoad()

Status: RESOLVED DUPLICATE of bug 115998

(Core Graveyard :: Java: OJI, defect)

Description

[Mark Bowles]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.3) Gecko/20030312
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.3) Gecko/20030312

A java.awt.Applet with a single extra method -- void println(Object x) -- is
called from Javascript during the onLoad event.  The java object is visible and
of the right type, but the method appears to be undefined.  Running this same
method from a later event, such as a button onclick(), works fine.

Using Sun j2re-1_4_1_02-fcs-linux-i586.  This problem occurs on Mozilla 1.3, but
also in 1.4b and Netscape 7.0.2 I never experienced it under Windows, but can't
test it, because my PC just died!

Reproducibility: this happens *almost* every time, but with repeated hits of the
"refresh" button on the browser, the method is *occasionally* found and run
successfully during onLoad().  Smells like a race condition...



Reproducible: Sometimes

Steps to Reproduce:
1.Build the applet and stuff it into the jar file.
2.Ring up the HTML page. Check the javascript and java consoles for errors.
3.Push the "view" or "run" buttons to try the function outside the onLoad() event
4.Check the consoles again

Actual Results:  
Javascript console shows '"document.embeds.theApplet.println is not a function'
when the attempt is made during onLoad(); the println does not take place on the
java console.

When the view button is hit, a legal native function is shown in an alert.

When the run button is hit, the java console shows that the println worked.

Expected Results:  
The javascript error is bogus; the function is there, but for some reason,
Mozilla can't find it during onLoad().

I'll attach the HTML and java files.

Reassigning to OJI component. This sounds to me like OJI bug 115998,
"Java - JavaScript onLoad event should fire after applet's init method"
