[rules-users] Issues with Eclipse Excel Plugin for Drools Decision Tables

[Vincent LEGENDRE]

Don't use eclipse to edit Excel files. Use Excel. I've never managed to make this OLE editor works well (but it is a long long time I did not retry, although I don't think there is any major evolution of this editor since then) . 
You can instruct Eclipse to use Excel to edit your .xls files (see configuration of File Types in Window>Preferences), or rigth-click + "open with system editor". 
The only thing to remember is to refresh your project if the Excel file is in a source folder. 

But the OLE Excel Eclipse editor is not a part of drools plugin (not sure your question should be here). You can find dozen of OLE editor for Eclipse on the net, if you really want to charge you with problems ...

Objet: [rules-users] Issues with Eclipse Excel Plugin for Drools Decision Tables 



Hi all, 

I am trying out Drools with JBoss Tooling in Eclipse. Actually, much of it does not work for me, but since there were not many complaints about that, I think it must be due to my missing experience. But now I have a couple of things that seem like bugs to me. (BTW, I mainly use Eclipse 3.7, but I also installed 3.6 to see whether anything is better with that - which generally it isn't. I upgraded Jboss tools to one of the newest nightly builds which I do not like, but only that solved the issue that the rules language dialects could not be found. I am using drools 5.2.0) 

I gave up on the Audit trail which always said "The selected audit log is empty..." (but it isn't and this should have been resolved two years ago according to some mails, but I simply avoid using that view). 

What bothers me most is that the Excel Plugin shows really erratic behavior in my Eclipse (both versions of eclipse). It opens the Excel file once (I converted to Excel 2003 (*.xls) from my newer version), but on the second time it says "Cannot create the in-place editor Reason: This is probably because there is no OLE editor registered against the type of file you were trying to access" Details say: File does not exist, is not accessible to user or does not have the correct format. result=-2147287008.) Sometimes later on it will work again, sometimes it won't and Excel complains about another Application needing to complete its OLE requests (until I shut it down using task manager since there is no alternative since it does not accept any input anymore). Sometimes even saving changes fails, leaving a corrupt file. Is that common behavior that others experience as well or is it just a local configuration issue? (Usually, I have no issues with my installation and I am not aware of configuring anything apart from using the Eclipse update sites.) 

Thanks in advance for any hints, 

Andreas
