Bug 43207 Javadoc info for content assist only shown once
I20030916 Javadoc infos for content assist are only shown the first time an editor is opened. Afterwards, no javadoc is shown any more. - open a java source file (e.g. public class A { }) - Press Ctrl+Space to invoke content assist => works: selection in proposal list shows javadoc hover (if javadoc available) - Press Esc, press Ctrl+Space again => fails: selection in proposal list does not make any javadocs appear
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/text/link/contentassist/CompletionProposalPopup2.java
if (!autoActivated)
						styledText.getDisplay().beep();
				
				} else {
					
					if (count == 1 && !autoActivated && fContentAssistant.isAutoInserting())
						
						insertProposal(fComputedProposals[0], (char) 0, 0, fInvocationOffset);
					
					else {
					
						if (fLineDelimiter == null)
							fLineDelimiter= styledText.getLineDelimiter();
						
						createProposalSelector();
						setProposals(fComputedProposals);
						resizeProposalSelector(true);
						displayProposals();
					}
				}
			}
