MySQL Stored Procedure: Source code not available

[ronald2016]

I used to be able to edit stored procedures in DBeaver, but this is no longer possible for me: the Procedure Source window now displays the message "Source code not available".

My setup is as follows:

DBeaver version 3.6.2
MySQL version 5.7.11
MySQL Plug-in version 2.1.12
Java version 1.7.0_95
JDBC driver: mysql-connector-java-5.1.38-bin.jar
Operating system: Linux Mint 17.3

Are there any additional plug-ins that need to be installed?

Thanks in advance for any help.

Looks like some bug but I can't reproduce that.
Please check Error Log (can be opened thru main menu Window) for any related errors. If there is anything interesting - please post full stacktrace of that errors.

The messages I can see in the Error Log do not seem to be related to this problem -- for instance

!ENTRY org.jkiss.dbeaver.model 2 0 2016-03-25 16:36:08.529
!MESSAGE Some data source listeners are still registered: [org.jkiss.dbeaver.ui.editors.sql.SQLEditor@512628c1]

!ENTRY org.jkiss.dbeaver.model 2 0 2016-03-25 16:36:08.582
!MESSAGE Some project listeners are still register: [org.jkiss.dbeaver.core.application.ApplicationWorkbenchWindowAdvisor@76b7fa87]

And I have just noticed that the same problem affects views as well! -- while trying to open a view's definition, the messages were

-- Loading '<view name>' source...
-- View definition not available

I have now upgraded DBeaver to version 3.6.2 on a machine that runs Windows 7 instead of Linux (with Java version 1.7.0_65 and MySQL 5.6), and procedure editing works perfectly there.

I wonder if this whole issue is limited to Linux Mint?

[Serge]

That's odd.
There is no difference between Linux and windows versions.
Try to reinstall DBeaver on you Linux. Remove previous version completely (your settings won't be lost) and install the fresh one.

I have now completely uninstalled DBeaver version 3.6.2 and installed version 3.6.3, but the problem is still there.

The data that is not being displayed in the Source / Definition / DDL panes seems to originate from LONGTEXT columns in the information_schema database:

PARTITION_EXPRESSION in the information_schema's PARTITIONS view
ROUTINE_DEFINITION in the information_schema's ROUTINES view
VIEW_DEFINITION in the information_schema's VIEWS view

My understanding is that LONGTEXT columns are stored separately from the other columns of a table, so I wonder if their storage implementation is operating system and/or file system dependent? Could that perhaps explain why DBeaver displays procedure definitions in Windows but not in Linux (Mint)?
