This is a small thing that I ran into when writing Decision Tables using OpenOffice:

Let's say in a CONDITION column you want to write the following pattern:

section : Section(type == "$param") from company.sectionList

If you type this into the column (without cut/paste) it will look like:

section : Section(type == “$param”) from company.sectionList 

The difference here is the double quotes generated by OpenOffice. If you do not change all of them and try to load your Decision Table with for example:

KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
DecisionTableConfiguration config = KnowledgeBuilderFactory.newDecisionTableConfiguration();
kbuilder.add(ResourceFactory.newClassPathResource("mydecisiontable.xls"), ResourceType.DTABLE, config);

you will get the following type of exception:

[8,29]: [ERR 101] Line 8:29 no viable alternative at input ''
[8,39]: [ERR 101] Line 8:39 no viable alternative at input ''
[9,29]: [ERR 101] Line 9:29 no viable alternative at input ''
[9,37]: [ERR 101] Line 9:37 no viable alternative at input '' 

...just something small to consider when debugging your Drools Decision Tables. Note that Decision Table support was added to Seam since 2.2.0.CR1

I've just found that the auto correction can be disabled with [Tools]->[Auto Correct Options] -> [Localized Options] in LibreOffice :)
