Hi All, i already found the caused of the problem it seems in v6.3 the behavior of modify is different than in v6.4. In v6.3 do-all-facts will not exit if the facts are modified. I replaced this with delayed-do-all-facts. I didn't realize that I was using CLIPSIDE v6.4 when I tested the CLIPS construct and CLIPS v6.3 for the embedded part. Thank you very much for your help and time

Modifying fact via call to (modify) action causes CLIPS to hang. I am trying to modify a templated fact. Here is the implementation: RULES: (deffunction reset-allowed-values "Resets allowed values" ; no argument ($?arg) (if (eq (any-factp ((?fact model1)) TRUE) TRUE) then ;T1_1, T2_1, T3_1 (do-for-all-facts ((?fact ar-node)) (eq ?fact:trip 1) (modify ?fact (allowed-values L D R A C S)))) MAIN: nt main(void) { DATA_OBJECT rtn; void *env = CreateEnvironment(); printf("Environment Created!\n"); EnvSetConserveMemory(env,...
