Editor screwing up - trashing project

Question

Several times now, I have been typing in the java backing bean code, and suddenly the editor hangs. For example, I had a try-catch block and wrote the catch as
catch {Exception e)
and the editor was no longer able to display the code. It could not draw the screen even!
It happened again today, and the jsp viewer can no longer display the GUI editor.  I do not know what I did to change it.
Part of the problem may be that I asked the GUI to manage a JdbcRowSetXImpl without letting it do the query since I need code like the following and do not think the GUI can handle it:
           curroleRowSet.setDataSourceName("java:comp/env/jdbc/policy");
           String [] choices = getSessionBean1().getCnChoices();
// Separate then with commas
StringBuffer sb = new StringBuffer();
for(int i = 0; i < choices.length; i++) {
sb.append("'" + choices[i] + "'");
if(i < choices.length - 1)
sb.append (",");
String query
= "SELECT ALL entityrole.Role FROM entityrole WHERE EntityCN IN(" +
sb.toString() + ")";
curroleRowSet.setCommand(query);
curroleRowSet.execute();

Ok, for the first case, I'm looking into it, but I am not noticing a problem.
Which update are you running ? If you are not running Update 6, then there are a number of issues that we're fixed that were directly related to this type of problem.
Can you give me more detailed information on what happens ? Are you switching between the designer and the java source editor ? Or just staying on Java source ? Waiting or it happens spontaneously as you type ?
Any information will help a lot to get me to reproduce this problem.
