Postback problem for SerialClob object bound to a TextArea component
by John Baker

Rate this Message:
I have an application that uses a converter to convert a CLOB type to String. The converter works and when executing the application, the converted value appears in a TextArea component. However, if I do a postback then I get an ambiguous error message in a message component. It seems that TextArea does not support *LOB types Is there any way to display the value of the CLOB in a TextArea? Or, I should bind the TextArea to a String then cache the CLOB value and use the converter to set the TextArea value?

John,
Having lurked on this list for several months, it appears lately that team members are very selective on posts they respond to. /David John Baker wrote: > > Does anyone reply to messages sent to this group ? > > John > > John Baker wrote: >> >> I have an application that uses a converter to convert a CLOB type to >> String.

This is because "we" (the former Woodstock development team) are no
longer assigned to Woodstock development. I have remained on the alias, in case I can be of help in my spare time. This means that if I am familiar with a problem I will usually respond. If I am not familiar with a problem and it will require as much investigation for me as the reporter, then I usually do not respond. In particular I don't respond to email that I cannot understand like this one that refers to "CLOB" which I do not feel like trying to figure out ;) -rick HandyGeek wrote: > John, > Having lurked on this list for several months, it appears lately that > team members are very selective on posts they respond to. > > /David > > John Baker wrote: > >> >> Does anyone reply to messages sent to this group ? >> >> John >> >> John Baker wrote: >> >>> >>> I have an application that uses a converter to convert a CLOB type >>> to String.

Thank you for posting, Richard. Until now, I had no idea that anything
happened to the team, other than a sudden and obvious silence. I would further suppose that you cannot elaborate on what we as users can expect with the future of Woodstock? No offense taken if you choose to ignore that question. Regarding the Character Large Object type (CLOB), John Baker is the Sun technician working this issue for me. The table component's Text Area will display CLOB data - but issues an obscure message on post back (for example, trying to edit, then post back the CLOB data). Refer to issue http://www.netbeans.org/issues/show_bug.cgi?id=148194 Best regards, David richard ratta wrote: > This is because "we" (the former Woodstock development team) are no > longer assigned to > Woodstock development. > > I have remained on the alias, in case I can be of help in my spare > time.

There seems to be some serialization issue with container session. at java.io.ObjectInputStream.<init>(ObjectInputStream.java:277) at org.apache.catalina.session.StandardManager.doLoad(StandardManager.java:428) at org.apache.catalina.session.StandardManager.load(StandardManager.java:372) Make sure that any ManagedBeans like SessionBeans can be serialized and resurrected correctly after being serialized. One sanity check my be to turn off session persistance in the container. This point I believe is well before the request is being processed by JSF, at least from the minimal stack trace shown. -rick > > Best regards, > David > > richard ratta wrote: > >> This is because "we" (the former Woodstock development team) are no >> longer assigned to >> Woodstock development. >> >> I have remained on the alias, in case I can be of help in my spare >> time.

I've resolved this. The object type returned by getAsObject() in the converter was not compatible with Oracle. Oracle JDBC APIs should be used.
