TRUE or FALSE Fails in %Evaluate Conditional Formula

Metastorm

The information in this article applies to:

Product: Metastorm BPM
Version: 7.0.1 7.5 7.5.x

Issue

• A dynamic role formula uses the %Evaluate function with a condition that evaluates a checkbox as TRUE or FALSE. For example,

  %Evaluate("(( (%Check1 = TRUE) )?("%User.Name"):("%system.users"))")

  This fails and an error similar to the following is written to the Designer log:

  Metastorm engine script evaluation call failed, reason <0x4f8e6a4>. Procedure Evaluate call failed. Position: 74

  A warning similar to the following may be written to the Windows application event log:

  Failed to evaluate the following - ,%Evaluate("(( (%Check1 = FALSE) )?(%"%User.Name%"):(%"%system.users%"))"),.

Resolution

• This is a known issue.

• Use 0 instead of FALSE and -1 instead of TRUE in the conditional formula with %Evaluate. The example above should be

  %Evaluate("(( (%Check1 = 1) )?("%User.Name"):("%system.users"))")
