[jboss-user] [JBoss jBPM] - bpel wait for

[pkovgan]

  I try to use <wait for="'PT15S'"/>, but it does not work!

  i have following steps:
   
  wait
  invoke
  wait
  invoke

  I also determined scheduler in web-xml file for 5000msc

  and It(a process) worked once, then repeatedly with interval of 5 sec produces exception:
