PK32705: CWBA TRANSACTION ABEND AWBM WHEN USING WEB STARTBROWSE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• CWBA transaction abend with dump code AWBM.
  .
  A WEB RECEIVE NOTRUNCATE does not receiving all the data.  This
  causes the position in the data to be maintained for subsequent
  receives.
  .
  The next command is WEB STARTBROWSE FORMFIELD which has to get
  the message body in order to process the forms data. This uses
  the same receive routine as the WEB RECEIVE. The saved position
  means that it gets part of the data.
  .
  This leads to a transaction abend in CWBA.

  * RECOMMENDATION:                                              *
  ****************************************************************
  An EXEC CICS WEB RECEIVE NOTRUNCATE is issued followed by an
  EXEC CICS WEB STARTBROWSE FORMFIELD. Both these requests utilize
  the proc webrequest_get_message_body. The RECEIVE NOTRUNCATE
  sets an offset which the STARTBROWSE erroneously picks up.
  DFHWBAPF assumes it has been called as a continuation of the
  RECEIVE and extract data from the saved continuation point.
  Later processing of this partial data, to extract form fields,
  fails and leads to transaction CWBA abending with dumpcode
  AWBM.

Problem conclusion

• The code used to process the WEB STARTBROWSE FORMFIELD has been
  amended.
  
  Prior to calling the common code, used to obtain the inbound
  data, any fields that may have been set by a previous WEB
  RECEIVE will be stored and their values set appropriately.
  This will prevent the common code from misinterpreting this
  command as a subsequent WEB RECEIVE, thus preventing any
  erroneous move of data.
  
  Upon return from the inbound data retrieval the stored field
  values will be restored.
