Cut and Paste on OS X does not work

Jonathan Marsden — Sat, 22 Mar 2008 21:12:02 -0000

Ed reported on the mailing list at

https://sourceforge.net/mailarchive/forum.php?thread_name=306f0afd0803200049k43eab651q2bfc05081543336f%40mail.gmail.com&forum_name=datavision-users

that Apple cut and paste worked fine in 1.1.0 but fails in svn revision r138.

This was tracked down by Ed, Frank and Jim to being caused by the use of the new "liquid" look and feel library.

Sorted reports do not work

Jonathan Marsden — Sat, 15 Mar 2008 04:35:16 -0000

When using the Report -> Sorted By... menu item to add a sort to a report, the resulting report always fails, which a traceback indicating that the field to sort by is not added to the SQL command being generated.

This is common to multiple backend databases.

Docs and code inconsistent re: optional output filename args

Jonathan Marsden — Sun, 24 Feb 2008 05:29:02 -0000

The DV User Manual indicates that the output file argument to each of the layout options can be omitted, in which case DV will create an output filename based on the layout filename.

However, in reality DV requires an output filename following a layout switch on the command line.

This request is to either change the documentation to match the code, or vice versa. CUrrently

datavision -h -n somereport.xml

fails, whereas the manual suggests it should work.

The workaround for now is to do

datavision -h somereport.html -n somereport.xml

instead.

Borders in SwingLE

Frank W. Zammetti — Fri, 04 Jan 2008 04:51:45 -0000

As pointed out by Pina on the mailing list, borders around fields when the report is run in the designer (and presumably running the report with the SwingLE outside the designer) do not show up. A sample report and data file are attached here. Exporting the report, say to PDF, shows the borders, so it definitely looks like some sort of issue with the SwingLE. Verified under XP and JDK 1.4.2 (thought it might have just been a JDK 1.5 or 1.6 issue, but doesn't appear to be so)

Quoting issues with some databases

Frank W. Zammetti — Sun, 19 Aug 2007 02:24:13 -0000

In some cases, reports written against certain types of databases, MySQL being a good example, won't work because DV generates queries with double-quotes, and the RDBMS doesn't like that (or the driver doesn't, either way, same result).

As one possible solution, provide a properties file that DV uses to look up the active database type (by JDBC driver probably?) and see what type of quoting to use. The DV JAR should contain a basic copy of this file, but on startup, DV should look for a version outside the JAR and use that if found so that someone could override the defaults without having to mess with the JAR or build DV from source.

There may be other approaches to solving this problem, but this seems like a reasonable answer to me at the moment.

NullPointer while trying to Copy Settings

Bud — Fri, 15 Sep 2006 22:00:42 -0000

In the create new report dialog, when I try to copy
settings from an existing report, after selecting the
existing report file I get the following:

DataVision v1.0.0
Error copying settings
java.lang.NullPointerException
java.lang.NullPointerException
at
jimm.datavision.ReportReader.removeReportSections(Unknown
Source)
at jimm.datavision.ReportReader.read(Unknown
Source)
at
jimm.datavision.gui.sql.DbConnWin.actionPerformed(Unknown
Source)
at
javax.swing.AbstractButton.fireActionPerformed(Unknown
Source)
...

I'm running on Windows XP with Java 1.5.0_06.
Everything else seems to work fine. The report file
that I'm trying to copy settings from is just a minimal
test report that runs against a remote mysql database.
I've attached the report file.

Rounding behaviour in SwingLE

Bytetron — Tue, 27 Jun 2006 11:02:02 -0000

The sum of the column Mai should be 10.75, but the
SwingLE does write 10.4999999... as you can see in the
attached pdf export on the last page. Perhaps as
suggestion there should be the possibility to set the
precision of numeric fields.

Cannot see all tables

Jonathan Levy — Tue, 13 Jun 2006 21:25:29 -0000

I created a simple report using data from a view in a
SQL Server 2000 database. It worked without
problems. Several weeks later, when I tried to load
the report, DataVision reported that it could not find
one of the fields, although I quickly determined that
it actually could not see the view at all or any
views/tables except one. The one exception was a
newly created table owned by the same SQL Server
account used for the DataVision connection. All other
views and tables were owned by dbo. When I changed
the owner of this new table to dbo and reloaded the
report, it worked and DataVision now can see all the
views and tables again. The SQL Server account is in
the dbo group and therefore has permissions to see all
the views/tables.

Interestingly, when I changed this table to be owned
by yet another account (expecting that DataVision
would no longer be able to see it), it still
appeared. The pattern seems to be that if any
views/tables are owned by the account DataVision is
using, only those views/tables appear. If not, all
views/tables appear.

This does not appear to be a JDBC issue. Another
application using the same driver can see all the
views/tables.

Badly formed SQL for MySQL

Steve Wilson — Tue, 16 May 2006 20:09:22 -0000

Attempting to run a simple report, I get a SQL error
back. This is the generated SQL:

select course."SO_SEC_NO"
from course

The quotes are the problem. They need to be gone for
MySQL to process this query.

trouble running datavision

Ed Davison — Mon, 10 Apr 2006 20:23:00 -0000

I have installed datavision on my Gentoo Linux workstation.

I get the following when I try to run datavision:

~ $ datavision
Could not find package datavision
Could not find package minml2
Could not find package jcalendar
Exception in thread "main" java.lang.NoClassDefFoundError:
jimm/datavision/DataVision
~ $

I definitely have datavision, minml2 and jcalendar
installed as you can
see here:

* dev-java/minml2
Latest version available: 0.3
Latest version installed: 0.3

* dev-java/jcalendar
Latest version available: 1.2.2
Latest version installed: 1.2.2

* dev-java/datavision
Latest version available: 0.8.2
Latest version installed: 0.8.2

Any thoughts or ideas?
