While executing the following rule, rule "home dummy" when pointId: Point(page == "home", region ="center-content") content: Content(id=="adslot") properties["type"]=="ad" from content then filter.put(content.id, true); end I get the following error: [ERR 101] Line 16:46 no viable alternative at input 'EQUALS' in rule "home dummy" in pattern PointId[18,16]: [ERR 102] Line 18:16 mismatched input '"type"' expecting ']' in rule "home dummy" in pattern properties The documentation explains that this is the most common error but I still struggle to understand the correct grammar for writing rules. Can anyone point me to a good resource (I even read the book "drools 5) for writing the following rule in a drl format? " If a Point has a page, "home" and region, "center-content" and the Content id is "adslot" with a property, type as "ad" then filter the Content (using a global map and passing a boolean flag) Thanks -- View this message in context: http://n3.nabble.com/Understanding-no-viable-alternative-errors-tp119375p...

Ah, that was an oversight. After fixing that, I now get ... mismatched input '"type"' expecting ']' in rule "filter content if advertisement" in pattern properties Is something wrong with this mvel syntax? properties["type"]=="ad" from content Pritam wrote: > > While executing the following rule, > > dialect "mvel" > import xxx.* > import java.util.* > global HashMap filter > > rule "filter content if advertisement" > when > point: Point(page == "home", region ="center-content") > content: Content(id=="adslot") > properties["type"]=="ad" from content > then > filter.put(content.id, true); > end > > I get the following error: > [ERR 101] Line 16:46 no viable alternative at input 'EQUALS' in rule > "filter content if advertisement" in pattern Point[18,16]: [ERR 102] > Line > 18:16 mismatched input '"type"' expecting ']' in rule "filter content > if > advertisement" in pattern properties > > The documentation explains that this is the most common error but I > still > struggle to understand the correct grammar for writing rules.
