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(); config.setInputType(DecisionTableInputType.XLS); 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
