When you float an element it becomes a block box.

You should always set a width on floated items (except if applied directly to an image - which has implicit width). W3C's Cascading Style Sheets, level 2, CSS2 Specifications states: "A floated box must have an explicit width..." If no width is set, the results can be unpredictable.

Format Only Edited LinesThe "Save Actions" is one of my favorite features in Eclipse 3.3 (read my original post about it). In Eclipse 3.4 there are several improvements including some new formatting features. One of the complaints against the Save Actions feature was that it will change the entire file, thus, making it very hard to compare to previous revisions when using a source control. It can become very annoying if some team members use it and some don't.For that purpose there's a new feature which allows changing just the edited lines, keeping the rest of the file intact. I highly recommend using the Save Actions feature. It is inactive by default, so go ahead and activate it.

A gotcha is a nasty surprise in the Java language or the standard libraries.

public void test_order_save() {    Order orderToBeFound = new Order(SOME_ID, SOME_NAME1);    orderToBeFound.save();    new DataStorm().show( connection, "SELECT * FROM orders o WHERE o.id = " + SOME_ID );    assertNotNull(orderToBeFound.load(SOME_ID));}

The most important new features in the JDT are: Rich hovers: Follow links in Javadoc hover Quick fix problems in problem hover Inspect variable values in the debug hover Java Editor Breadcrumb: Know where you are while in the editor Various Content Assist improvements SWT Templates: Build your UI the fast way Format edited lines on save: Keep outgoing changes to a minimum Extract Class refactoring: Replace a set of fields by a new class Compiler supports multi CPU-machines: Compile your workspace faster
