Description herent 2013-05-08 22:44:01 UTC 
This bug was originally marked as duplicate of bug 219862, that is already resolved. This bug is still valid, so this seems to be another bug, but it might be related.

Build: NetBeans IDE Dev (Build 201304292301)
VM: Java HotSpot(TM) 64-Bit Server VM, 23.21-b01, Java(TM) SE Runtime Environment, 1.7.0_21-b11
OS: Linux

User Comments:
herent: Just editing a CSS file. Nearly every keystroke was throwing up this error. I was at the bottom of the file (18 lines long, not much there at all, no complicated selectors or nested brackets or anything) trying to type .sem-field-container 

It seems like these CSS errors show up when you are editing a line of css that is incorrect at that particular moment, so if you are missing a comma or have rules with commas but no brackets, then the error will show up.

Honestly, if these errors are in the production release, I will have to find a different IDE. Most of what I do involves CSS.

I had this css file:


root { 
    display: block;
}

.eas-asda{

}

.nic


And I typed {} after ".nic"

This issue is caused by updating between dev builds which is not supported scenario. Will definitively not happen in production.

Oops, pls disregard this.
Comment 6 Marek Fukala 2013-05-09 06:41:09 UTC 
100% reproducible on Vlada's sample: 
1) type the {} after the last rule, 
2) and then delete it.
