Massimiliano Perrone commented on SYNCOPE-21:
---------------------------------------------
Hi guys,
after downloading Activiti5.9 source, our workflow engine, I debugged to
understand the root cause of this issue.
Activiti has follow Java Class:
public class GetNextIdBlockCmd implements Command<IdBlock> {
private static final long serialVersionUID = 1L;
protected int idBlockSize;
public GetNextIdBlockCmd(int idBlockSize) {
this.idBlockSize = idBlockSize;
}
public IdBlock execute(CommandContext commandContext) {
PropertyEntity property = (PropertyEntity) commandContext
.getPropertyManager()
.findPropertyById("next.dbid");
long oldValue = Long.parseLong(property.getValue());
long newValue = oldValue+idBlockSize;
property.setValue(Long.toString(newValue));
return new IdBlock(oldValue, newValue-1);
}
}
This class uses a ACT_GE_PROPERTY table to retrieve "next.dbid":
SELECT * FROM ACT_GE_PROPERTY;
NAME_ VALUE_ REV_
schema.version 5.9 1
schema.history create(5.9) 1
next.dbid 101 2
historyLevel 2 1
So, in my opinion, the problem is that ImportExport Syncope Class doesn't
export this table :)
// these tables must be ignored
if (!tableName.toUpperCase().startsWith("QRTZ_")
&& !tableName.toUpperCase().equals("ACT_GE_PROPERTY")) {
tableNames.add(tableName);
}

> Reporter: fabio martelli

> Labels: workflow
>
> When starting with an empty database, Activiti just creates its own tables
> and everything goes smooth: when, instead, the database is already populated
> (including Activiti tables), an exception is thrown, reported below.
> I can guess that this is happening because there is a sort of incremental

> ACT_HI_ACTINST table.
