"Current tabular form data is too old" on apex 4.2

jmarcOct 25 2012 — edited Nov 23 2012
hello,

we have install apex 4.2(embedded pl/sql gateway) on an oracle database 11.2.0.2(windows 2008 server) .


we create a tabular form and validations on it .

when a validation fail on tabular form, we have the error :

Current tabular form data is too old; the source data has been modified.
Click here to discard your changes and reload the data from the database.


so, i try to reproduce with the "sample tabular form" .

i install the sample ,
i run the sample and choose the tab "Employees".
I click on the button "add a row",enter a name "DUPONT" and choose to "apply changes" .

so i have the 3 errors validation
3 errors have occurred
•Job must have a value. (Row 11)
•Hiredate must have a value. (Row 11)
•Department must have a value. (Row 11)


these 3 errors are expected,

but also
the error
Current tabular form data is too old; the source data has been modified.
Click here to discard your changes and reload the data from the database.

i try with different internet browsers(firefox, IE, google chrome) but the error always occurs .


i try to reproduce on apex.oracle.com with no success.



regards
jm

Your query might win the award for the "shortest question with the longest answer", but I'll try for a short answer. For the first part, you need to fetch data from the database. For this you could use anything from raw JDBC to an Object Relational Mapping (ORM) tool, like Hibernate. For the second part, I would recommend a reporting tool, like Jasper Reports, BIRT or ReportMill. Currently, only ReportMill has generated reports in JavaFX. But they all generate PDF - and that would be my suggestion: generate PDF and use the platform PDF viewer to display and print reports. You could spend years trying to duplicate all the nice display and print functionality found in Acrobat Reader and Mac OS X Preview.

As it happens, ReportMill (disclosure: me) is working on a tool to do exactly what your question asks for:

There is also a very cool database tool that has JavaFX support called XDEV. We'll both be at JavaOne.
