Re: [rules-users] Creating HashMap object in rules
Hi Esteban,
Values of @{Result1}, @{Result2} & @{Result3} are unique values in my excel
and they are not null, but when i try to get the hashmap(i.e. $rule) from
array list(i.e $testObj.getResult() return an array list) in my java code it
just return null as if the Map $rule = new HashMap() is completely ignored when it comes out of drools working memory.

[rules-users] empty cell in excel makes the LHS missing in the rule
Hi, i am using drools 5.4.0 and currently facing a typical problem. when ever any cell for LHS in the spreadsheet is blank. when the rules is compiled using the spreadsheet, the LHS for the empty cell get completely missed. drools don't even consider it as a empty string. The only workaround i found is to fill all empty cell with N/A and then merging the cells, which looks like a patch work. Any other way thru with i can tell drools to treat empty cells as empty string? - Thanks...
