Overview:
---------
If the ETable.getColumnDisplayName(String) method is overwritten to convert column names to localized strings, the ETable will not display the translated value for a single sorted column. Unsorted columns display the translated value, also if you sort more than one column, the translated values are displayed correctly. This only happens if you sort by a single column.


Steps to reproduce:
-------------------
1) Create your own class which extends from ETable. Overwrite the getColumnDisplayName(String) method to convert column names to localized strings.
2) Embed your ETable in a GUI and click on a column to sort it.


Actual Results:
---------------
The sorted column (which is now bold and contains a sort arrow) will now display the 'technical' column name instead of the localized one. 
NOTE: If you sort more than one column (by holding shift while clicking on a second column), the column names are displayed correctly again.


Expected Results:
-----------------
The sorted column should also display the localized value returned by ETable.getColumnDisplayName(String)


Build Date & Platform:
----------------------
Product Version: NetBeans IDE 7.0 (Build 201104080000)

System: Linux version 2.6.32-30-generic running on i386; UTF-8; en_US (nb)


Additional Information:
-----------------------
The behaviour seems to occur due to an unhandled case in the ETableColumn.ETableHeaderRenderer class (http://hg.netbeans.org/main/file/4d131b1ab21b/o.n.swing.outline/src/org/netbeans/swing/etable/ETableColumn.java) on line 606. If the 'sortRank' of the column is not 0, but 'sortedColumns.size()' is 1 (which is true since this bug occurs if only one column is sorted), we do not call 'label.setText(valueString);' which would set the internationalized value, but leave the current label value which was filled by the headerRenderer and therefore is set to the untranslated value.
