Indeed. It seems that, from 5.2.0 on, when there is a DRL file containing a function with a signature that contains a parameter that is an array of some simple type foo (int, double,...) and a scalar parameter of the same type and another function with a similar signature, an inappropriate syntax error is flagged: [ <functionname> : unable to resolve type while building function ] E.g. function nextPoint( int[] a, int n ){ } function prevpoint( int[] a, int n ){ } @ru: Splitting the DRL might be a workaround, but this might not be easy as this is generated code. -W On 16 August 2011 17:10, ru <sorokin(a)oogis.ru&gt; wrote: > Situation definitely treaky - I am working as author on DroolsTab plugin > to > Protege (http://protegewiki.stanford.edu/wiki/DroolsTab).

Maybe this should be reported as a new bug to Drools team? -- View this message in context: http://drools.46999.n3.nabble.com/Functions-with-array-parameters-double-...
