Error description

• In Rational Business Developer 9.0.x, when submitting a value
  via JSP, the following error (or similar) is generated:
  
  'EGL0731E J2EELib SessionAttr function failed with key, mykey.
  Error: For input string: ''
  EGL0002I The error occurred in index processing the
  onConstruction function.'
  
  This happens when the attribute submitted is numeric.
  
  bstract: ATTEMPTS to submit a value via JSP may result in a
  J2EELib SessionAttr error.
  
  Sample code:
  ------------
  function onConstruction()
   rec arrayRec;
   rec.array[1].myfield = 123;
   SysLib.writeStdout(rec.array[1].myfield);
   SysLib.writeStdout('before setSessionAttr');
   j2eeLib.setSessionAttr('mykey', rec.array[1].myfield);
   SysLib.writeStdout('before getSessionAttr');
   j2eeLib.getSessionAttr('mykey');
   SysLib.writeStdout('after getSessionAttr');
  end
  
  Output:
  -------
  before setSessionAttr
  before getSessionAttr
  EGL0731E J2EELib SessionAttr function failed with key, mykey.
  Error: For input string: ''
  
  Using rec.array[1].myfield in j2eeLib.setSessionAttr is the
  cause, since, if rec.array[1].myfield is saved to a string
  variable faa that
  is given as the parameter for j2eeLib.setSessionAttr, then no
  error occurs.
  
  Local fix:
  A workaround is to store the attribute as a string before
  calling j2eeLib.setSessionAttr.
