Hi Gal, thank you for sharing the gwt ant build script.
The script wasn't the problem, I was able to compile the source with
the default ant build script. The problem was that compiled code from
Eclipse worked but from command line didn't.
Today I made some other tests and I finally I identified the problem.
I compiled the source code in Eclipse using DETAILED, PRETTY and
OBFUSCATED output. And I did the same with the ant script. Then I
compared them.
I was hoping to see some differences in Eclipse generated code and in
command line, but to my surprise all generated files were binary
identical! => it was not problem of compiling.
Then I deployed to the test environment each version. OBFUSCATED
version failed with error. But, when I deployed PRETTY and DETAILED
versions the code worked!
So it also explains, why I wasn't getting errors from Eclipse build,
because output might have been set to PRETTY / DETAILED. Ant script by
default produces obfuscated code.
Here is a code snippet from the native method, that fails:
public static native String parseJSON(String json) /*-{
var retval = [];
try {
var x = 0;
if (json != null) {
var obj = eval( '(' + json + ')' ); <---- HERE IT
FAILS
var entries = obj.feed.entry;
I was getting error 'Can't find variable obj'.
I've replaced the eval function with JSON.parse method (http://
www.json.org/js.html) and included json2.js file in the entry html
file, but it is still the same. Obfuscated version doesn't work and
I'm getting the same error 'Can't find variable obj' while detailed
version works.
Any ideas?
