Description Vincent CLA 2011-07-08 06:01:40 EDT 
Build Identifier: 3.7.0

When comparing 2 folders with differents php files, and making changes to a file, an error occured when saving the modified file : 

"Save" did not complete normally.  Please see the log for more information.
org.eclipse.php.internal.ui.compare.PhpMergeViewer cannot be cast to org.eclipse.compare.contentmergeviewer.ContentMergeViewer

The same file comparison works fine if it's done directly between the 2 php files (and not on their parents folders)

Reproducible: Always

Steps to Reproduce:
1. Select 2 folders (each folder containing a different version of a file 'test.php') and click on "compare with" > "each other"
2. On the 'Compare' windows click on the php file to open the compare file view
3. Select a difference, and click on the "copy current change ..." arrow to modified the file
4. Save the modified file with ctrl+S

This is also happening in Eclipse 3.7 on Mac OS X 10.7 Lion - fresh install of both.
Comment 2 Zhongwei Zhao CLA 2011-08-23 02:50:39 EDT 
fixed in head
Comment 3 Kalin CLA 2011-10-18 06:22:25 EDT 
Still reproducible.
I got the following in a the log:
