Status: RESOLVED DUPLICATE of bug 334256

(Core :: DOM: Editor, defect)

Description

[Hannes Verschore [:h4writer]]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; nl; rv:1.8.0.7) Gecko/20060921 Ubuntu/dapper-security Firefox/1.5.0.7
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; nl; rv:1.8.0.7) Gecko/20060921 Ubuntu/dapper-security Firefox/1.5.0.7

If you set the selectionStart and selectionEnd on a empty line, the caret comes on the line above.

Reproducible: Always

Steps to Reproduce:
(see my testcase)
1. Click on "Put the caret on place 11"
2. Click on "Put the caret on place 12"
3. Click on "Put the caret on place 13"

Actual Results:  
1. the caret comes on de second line after the d
2. the caret comes on de second line after the d
3. the caret comes on the fourth line before the d

Expected Results:  
1. the caret comes on de second line after the d
2. the caret comes on de third line
3. the caret comes on the fourth line before the d

- After you set the caret on the third line yourself (with your mouse), the testcase will work like expected. If you set the caret on another line (with your mouse), javascript will again makes mistakes
- It seems that it occur when you have a 2 \n after eachother.
