updating rich:dataTable contents
Hi All,
I have created(using jsf1.2 and richfaces) a page which list the students , when the page opens it lists all the students ,
For the purpose of search I have tried to use filterBy but the problem with it , it allows fitlering based on first character , that is why I have added to the page inputtext to search for a particular student name (even so if the typed character is at the middle of the name),
the problem is that when i search for a student i got the desired result for search but the datatable contents will not be updated accroding to the search result
any way to fix this issue ?
