Fellows,
Recently we asked Cosylab to update an PVA plugin in OpenXAL that they did a couple of years ago. The old versions in question are:
Now we got the following report:
- In the newest version of pvDatabaseJava a class used by the pvAccessPlugin is not present. This is preventing the pvAccessPlugin to build. A temporary solution is to
copy the implementation of this class from the previous version of pvDatabaseJava to the pvAccessPlugin.
- I have inspected the source code and it appears the newest version of pvAccessJava is still not implementing read/write for PVAs. I have also checked this with Matej Sekoranja, who confirmed this isn't yet implemented. - I have used the current version of the pvAccessPlugin from the bitbucket to run a virtual accelerator and then try to connect with scanner application. I was able to add a PV, however the values did not change if we run the virtual accelerator. It seems that the connection cannot be established between Scanner and VirtualAccelerator. The result for updated pvAccessPlugin that is using the newest pvaAccessJava libraries is the same. I have tried quickly troubleshooting the connection, but have not managed to find the cause. Can this be true (write, or put not implemented)? This would be a stunning surprise to me. Or am I missing something?
Best regards,
Timo
