Hi all, I am using the latest Guvnor release (5.1), and I have the following DSL expression where I use "-" to have conditions on multiple lines: [when] There is an Asset=asset:Asset() [when]- name is empty=eval(StringUtils.isBlank(name)) [when]- tag is empty=eval(StringUtils.isBlank(tag)) Having these DSL expressions, I wanted to create a rule, but I ran into some issues. To summarize: There seems to be a parsing error, when conditions are added in DSL using "-". Did anybody else run into this problem? I wonder if I do something wrong, but, re-creating the DSL to have the 2 conditions into one expression, is all working fine. It may be a combination of "-" and eval? Below, is the description of rules created, and error I got. First, I created a rule using the above DSL expressions in the BRL editor. While the rule looked ok in the editor, and it validated fine, only when I checked the source I noticed is wrong. So, the rule source looks like this: rule "test_dsl" dialect "mvel" when asset:Asset( eval(StringUtils.isBlank(name, eval(StringUtils.isBlank(tag)) )) ) then asset.setStatus("INVALID") end It looks that the conditions are parsed incorrectly, and the second eval condition is added as a parameter to the StringUtils.isBlank from the first eval. Also, all the right parenthesis are added at the end of the expression. If I add one condition at a time, it all works fine. The error is when I have more than 1 condition. So, I created a new DSL, that contains both conditions into one line, eliminating the hyphen between conditions: [when] There is an asset with name empty AND tag empty =asset:Asset(eval(StringUtils.isBlank(name)),eval(StringUtils.isBlank(tag))) Using BRL editor, I created a second rule using the DSL above. The rule validated ok, and the rule source looks fine: rule "test_dsl_1" dialect "mvel" when asset:Asset(eval(StringUtils.isBlank(name)),eval(StringUtils.isBlank(tag))) then asset.setStatus("INVALID") end I created a test for this rule, that ran correctly.
