Non Serializable Exception and Illegal State Exception in ExtendedDatatable

[iegle]

Good morning!

I've been working with Richfaces for a just little time yet, and encountered that problem I couldnt solve. Im loading data from a mysql db, words with some number attributes. Im trying to list them in an extended data table and on click show some detailed information about them. I keep getting NonSerializableException and IllegalStateException. If I use a simple model with only 2 strings and put it in the extendeddatatable-> no problem. but as soon as i take a little more complex model 1 string, 5 ints i get these errors. Can anyone tell me where they get thrown or how to resolve them. thanks in advance

Hello Philip,

make Word and ResultTableBean implements serializable, then test it again.

regards.

hi abrahim, very useful advise thanks! before i made the mistake to make only resulttablebean serializable, but not word. now it works with a small amount of words in the table, but i passed on about 40.000 words to the list/table, and then keep getting the

SEVERE: javax.faces.FacesException: Cannot create a session after the response has been committed

javax.faces.FacesException: Cannot create a session after the response has been committed

error.

fixed illegal state exception by making all instance variables in resulttable bean transient and worddao serializable
