An Obscure JDeveloper Bug

ADF bug: missing af:column borders in af:table for IE7

There’s a rather obscure JDeveloper bug that only effects IE7, for af:columns in af:tables that show af:outputText fields based on dates that are null (phew, try and say that with a mouth full of wheaties). It occurs in 11.1.1.4.0 and 11.1.2.0.0 (and all versions in between it’s assumed).

In the previous picture from IE7 if you look closely, you’ll notice that the HireDate2 column has lost its border for the null entries. Note the other columns even when they are null, still have a border.

If we look under IE8 (or any other browser for that matter) we see the problem doesn’t occur at all:

The problem is being caused by 2 separate issues:

  1. IE7 does not render borders for HTML table cells (ie. the tag) if the cell contains no data. This can be fixed if the cell contains a   tag.
  2. ADF Faces RC includes the   tag for empty table cells, except for null date af:outputText fields who in addition have child tags that aren’t converter and validator tags.
