IDE log

Please make sure that you have JS hints enabled in Tools > Options > Editor > Hints > JavaScript. If JS hints are enabled and the issue is still reproducible, please try to run NetBeans with clean user directory [1].

I believe that this should help. If not, please reopen this issue and provide us more details, since I am not able to reproduce the issue. Thanks!

If everything is ok, what Roman mentioned, could you provide example? Thanks

JS hints are enabled.


executed

C:\Program Files\NetBeans 8.0\bin>netbeans64.exe --userdir d:\xxx

JS-Editor works fine as expected, however Netbenas 8.0 is up and running 
not Netbeans 8.0.2  


When runnig from my desktop shortcut with these settings

Targte: "C:\Program Files\NetBeans 8.0\bin\netbeans64.exe"
Execute in: "C:\Program Files\NetBeans 8.0"

netbeans 8.0.2 comes up but JS editor is not working.


confusing !

Petr Pisl is asking for example, please tell me what exactly do you need.

It looks like the comment block below, at the very top of a JS file
is causing these problems. Seems that the starting pattern '/****'
causes this.

Yesterday I have tried it only on the dev build and the issue is NOT present in the current DEV build, hints are shown, regardless of the file header (even with the same as mention in comment #5)

Product Version: NetBeans IDE Dev (Build 20150605-bc70ce340f9c)
Java: 1.7.0_80; Java HotSpot(TM) 64-Bit Server VM 24.80-b11
Runtime: Java(TM) SE Runtime Environment 1.7.0_80-b15
System: Linux version 3.13.0-37-generic running on amd64; UTF-8; en_US (nb)

------------------------------------------------------

But it IS reproducible in 8.0.2 with the latest patch. Reporter is right, if JS file has a header which starts with "/**" (note the two asterisks), then hints are not displayed and coloring is wrong (e.g. function name).

Product Version: NetBeans IDE 8.0.2 (Build 201411181905)
Updates: NetBeans IDE is updated to version NetBeans 8.0.2 Patch 2
Java: 1.7.0_80; Java HotSpot(TM) 64-Bit Server VM 24.80-b11
Runtime: Java(TM) SE Runtime Environment 1.7.0_80-b15

Moreover it seems that even a comment (not a header) inside the file which starts with "/**" and has certain length causes the issue on 8.0.2. If the comment is short enough, the issue is not present.

So it seems like a regresion in 8.0.2. In dev builds it's not reproducible.

Because it works in dev build, I'm marking this issue as fixed in dev build.
