Title: Access via Java / changes to model not represented / stale data in <model>.qea?
Post by: Bastian_ on January 30, 2023, 07:54:10 pm

Hi,
I have a problem with stale data, which happens when accessing an EA model through the Java interface while it is also opened in EA.

I see the following happening:
1. I have my <model>.qea open in Enterprise Architect v16 (Build 1604) and did some changes (usually to the model elements or diagrams-layouts). In the file system at this point, a <model>.qea-journal file exists.
2. Without closing the file in Enterprise Architect, I start a self-written Java-program (which uses org.sparx.Repository) to extract information from the <model>.qea file (export diagrams as images and export parts of the model as XMI).

Problem: the changes already done to the model in Enterprise Architect are not represented in the data I extract through the Java program.

I suspect, this might happen, as the Java is explicitly accessing the <modeL>.qea and the changes have not yet been flushed to that file but reside in the <model>.qea-journal?
Once I have closed the file in EA, the Java program extracts the corrrect data including all changes done via EA.


So my questions are:
1. Is what I suspect correct - if not, what is causing this?
If yes:
2. Is there something I can do from the Java-program's side, make EA flush changes from the Journal into the model-file?
3. Is there an interaction within EA (alas there is no "Save now" button), to make EA flush changes from the Journal into the model-file?

Any help would be greatly appreciated - thank you for reading this far

Start by trying again with the latest version. (16.1.1623)

There have been some reports of this type of weirdness using the early V16 versions

Thank you for the quick advice! I'll try that and report back here, once I see the results.

Hi Geert,
I've been running the latest Version of AE now for some time and the problem I had has not come up since then.
Thank's again, for your help
