Description brettz9 2008-11-30 22:13:13 UTC
There has been apparently a major regression in 6.5 regarding JavaScript processing (in a JavaScript file), at least
with E4X:

In just typing the following into a file, it seems to work

function a() {

But if you accidentally hit return after the ".", and then do an 'undo' (or otherwise delete the whitespace just added),
a red exclamation mark appears indicating an error, where there is no error (nor was there any error caused by adding
the whitespace).

This problem does not occur in 6.0.

Similar problems occur if you start with this valid code:

function a() {
and then collapse the whitespace.

Due to this problem, I am still running 6.0
Comment 1 Torbjorn Norbye 2008-12-01 01:20:11 UTC
This is unrelated to E4X; this was a bug in incremental parsing, introduced in 6.5 for performance reasons. (I hope you meant you were using 6.1 instead 
of 6.0 since the 6.1 JavaScript support should be quite a bit better than in 6.0).

A workaround is to modify any line outside the current function.

I've fixed this in changeset 78dd0b148881. Regression test is JsParserTest.testIncremental7.

I'm going to nominate this for a 6.5 patch; QE can you verify the fix in the trunk? Build 4455 or later from

Fixed in 7.0M1.

Comment 2 brettz9 2008-12-01 04:33:04 UTC
Yes, sorry, I forgot to change that part of my post, that it was not only for E4X. 

And yes, sorry, I was using 6.1 (Early Access PHP).

The issue hasn't passed the nomination process for 65patch2 by cut-off date. It has been moved to 65patch3.
