advice about dependency injection

I have 3 beans: beanA, beanB and beanC.

Both beanA and beanB uses beanB (ArrayList), from beanA i only remove itens
from beanB and from beanC i add, get and set a item in beanB.

Everything is ok when beanC to these operations on beanB but if i try to
remove an item from beanA i'm getting an IndexOutOfBoundsException.

Note: i'm using saveState in beanA

I'm following this wiki entry:

http://wiki.apache.org/myfaces/AccessingOneManagedBeanFromAnother


Please somebody help me.

I put the code beanB.size() >= myTable.getRowIndex() before remove the item
and now the item in ArrayList is never being removed.

RE: advice about dependency injection

The example isn't very clear but based on the below

public void removeItem(ActionEvent event)
     {
         beanB.remove(myDataTable.getRowIndex());
         return null;
     } 

Have you tried catching IndexOutOfBoundsException in the above method?  Also, why return null?  In any case, I would have an if (beanB.size() >= myTable.getRowIndex()) or so to prevent any such problems.

Hope that helps,

James

hi rogerio,

this is your second message with same text, i think you should describe your
problem more clearly, and give a piece of real java code...
