  • Adding Refresh Tag to View

    - by RJL
    I need a view to refresh automatically every 20 seconds, and have added the following code to the view header via the views GUI - with no success. The code (or portions of it) are simply displayed on the view and no updating is performed. I've tried omitting both and just the ending ?php statement. If someone can tell me the proper code to use, or a better approach at updating the view automatically, I'd be very appreciative. Thanks. print ";

  • auto-import of packages across project in eclipse

    - by Reddy
    I have used file search functionality in eclipse to replace a specific occurrence of text with a replace text which contains a java method name in all files across the workspace. But now in all those files I have to add the import statement (for the method name to resolve). Is there an automatic way of doing this instead of manually searching and importing the package myself in all files?

  • MySQL Order By Problem, Why is 1000 being seen as Smaller than 2?

    - by Jack
    I have a strange problem, I am trying to order the output of a set of records by a field called displayOrder. Now even though record A has a displayOrder of 2 and record B has a displayOrder of 1000, record B still shows up before record A. Here's my select statement: SELECT * FROM items ORDER BY displayOrder ASC It works fine until I have a record greater than 9, then 10, 11, 12, etc are seen as smaller than 2, 3, 4 because they start with the number 1. Any way to fox this?

  • Is it standard behavior for this code to throw a NullPointerException?

    - by Eric
    I've had a big problem in some library code, which I've pinned down to a single statement: System.out.println((String) null); Ok, the code doesn't actually look like that, but it certainly calls println with a null argument. Doing this causes my whole applicaio to throw an unexpected NullPointerException. In general, should println throw this exception under that circumstance, or is this non-standard behavior due to a poor implementation of the out instance?
