I am using using Vaadin 6.7.0 for my web application.
I found out that TreeTable removeAllItems() method does not work.
I came across a forum which said that this bug has been fixed in version 6.7.1.
I cannot switch from Vaadin 6.7.0 to Vaadin 6.7.1 as this decision does not lie in my hand.
I tried to override the removeAllItems() within my TreeTable but it gives me a NullPointerException somewhere in the removeItem(Object) method.
Following is the code-
@Override
public boolean removeAllItems() {
for (Object itemId : getItemIds()) {
super.removeItem(itemId);
}
return true;
}
What can be the possible work-around which will let me clear the TreeTable?
Help is very much appreciated.
Thanks.
I took a quick look at the ticket and the patch and as far as I can see, there’s no simple workaround. I guess the simplest way without updating the Vaadin version would be to just remove your TreeTable completely and create a new one (and replace the old one with it) whenever you need to remove all the items.
Another option is to create your own custom version of treetable with a corresponding client-side class that would then include the fix. This might be quite a bit more work, since the fixed code seems to be in a private method of VScrollTable class.
Removing the TreeTable and replacing it with new one was the last thing on my mind.
But it seems thats the only potential solution now.
I tried it and it works fine. I had to re-create the TreeTable, replace old one with the new one and also had to set a new empty container to it.
Thanks for the help.
I did not have to spend time finding some other workaround.
