Hi!Are You sure that your ArrayList is not empty? Can you post here your code. It is hard to find possible problem without application.Thanks,Roman.

Hi Roman,

Thanks for replying. For a moment there, I thought I was being blacklisted ;-}

In the application, I have a dddlist and a table. The values in the table are dependent on the ddlist value selected. In other words, if a user chooses ABC in the ddlist, the values in the table would be "A" ,"B" ,"C". However, if the user chooses DEF in the dropdown, then the values in the table would be "D","E","F"

It goes one step further...the selected value in the ddlist is coming from a previous page (passed thru the URL). However, the user can change the value, and the table is populated automatically. There is also a text box and a button if the user wants to search the existing options in the table.

Now for the code:

The pre-renderer method:

//pid: value from url

//SearchParam: value from textbox. It is set to % if user does not enter anything

if (pid != null && (SearchParam != null) ) {

//Sgroup_tblRowSet3: rowset that table is bound to

getSessionBean1().getSgroup_tblRowSet3().setObject(1, pid);

getSessionBean1().getSgroup_tblRowSet3().setObject(2,SearchParam);

getSessionBean1().getSgroup_tblRowSet3().setObject(3,SearchParam);

getSessionBean1().getSgroup_tblRowSet3().execute();

ddPG.setSelected(new Integer(pid));

}

getSgroup_tblDataProvider().refresh();

Any suggestions?

Thanks

Hi!Are You sure that your ddlist had been initialized before You've tried to set selected it's item?Try to debug prerender() method and find out is your ddlist initialized?Thanks,Roman.

I'm trying to do that now....What puzzles me though...is that it works well most of the time...only once in a while I get this error.

I did debug the program, and yes, the list is initalized before the setSelected()

Hi!

Why you perform getSessionBean1().getSgroup_tblRowSet3().execute();?

Why You don't use getSgroup_tblDataProvider().refresh();?

I can't understand where is problem, but try to call getSgroup_tblDataProvider().refresh(); instead of getSessionBean1().getSgroup_tblRowSet3().execute(); and only then call ddPG.setSelected(new Integer(pid));

Maybe something wrong with execution of RowSet.

Thanks,

Roman.

I cannot use the getSgroup_tblDataProvider().refresh(); since at no point in time is the rowset executed.I need to execute it before I can refresh it. This is the rowset that populates the table.

Hi!

I always do like this:

getSessionBean1().getMyRowSet().setObject(myIndex, myValue);

myDataProvider.refresh();

(myDataProvider is bound to myRowSet) and all works fine.

I'm not insist, I just try to figure out where is the problem. I thought maybe it is in execution of RowSet.

Thanks,

Roman.

My main problem is that I don't know when the error will occur, so I don't know if it's fixed or not.

Another runtime error that I am sometimes getting is: javax.faces.FacesException: javax.faces.FacesException: Can't instantiate class: 'consdb.tasu.tasu_menu'

Again, when I refresh the browser, all goes well. I am getting really frustrated with these runtime errors that happen whenever they want to.

Hi!Try to deploy on another server (Tomcat for example). Maybe it's application server problem.Thanks,Roman.

I did deploy on Tomcat, thinking that it was server based error like u.Didn't see the "can't instantiate class error" as yet. However the error: "Index:0, Array:0" , I've seen
