Description Marvin Fröhlich

2010-05-19 11:12:58 EDT

Build Identifier: 20090920-1017

When I edit code like the following

##########
aaaaa bbbbb|b ccc ddd eeeeee ffffff;

ggg hhhhh iiiii;
##########

and the caret is where the pipe symbol is in the first line and I then go down with the caret by one line and then down to the third line the caret will most probably be at the line start of line 3.

Normally one would expect the caret to be after the 1st 'i'.

There seems to be a hardcoded (?) delay after which the caret is reset to the current column (line start of line 2 in the above example), which is way too short.

The delay seems to be even shorter when uncompilable code is being edited.

The delay should either be enlarged by some times or made configurable in the preferences.

Reproducible: Always

Which editor are you talking about?

Do you also see it when using the (default) Text Editor?

I am using the Java text editor. And it doesn't seem to be in the normal text editor.

I cannot reproduce this using 3.6 RC1 or N20100517-2000. Maybe the given example is not enough and the jump is caused by something else (e.g. a view setting back the selection).

Please try again using latest Eclipse SDK build:

If you can still reproduce then please provide more detailed steps.
