There was a bug in handling JDO delete queries. Please try build 2.7.1_07.

Please read carefully the posting instructions - before posting to the ObjectDB website.

  • You may have to disable pop up blocking in order to use the toolbar (e.g. in Chrome).
  • Use ctrl + right click to open the browser context menu in the editing area (e.g. for using a browser spell checker).
  • To insert formatted lines (e.g. Java code, stack trace) - select a style in the toolbar and then insert the text in the new created block.
  • Avoid overflow of published source code examples by breaking long lines.
  • You may mark in paragraph code words (e.g. class names) with the code style (can be applied by ctrl + D).
  • Long stack traces (> 50 lines) and complex source examples (> 100 lines) should be posted as attachments.
