TreeByNestingTableColumn - NullPointerException

[former_member194668]

Hi Gurus,

I'm trying to display a tree inside the table. For this purpose, I used TreeByNestingTableColumn. We are on 7.0.13.

Scenario: In the first, when search results are empty it is working fine. Once the table is loaded with data and I search again, if the data is empty then it is throwing up NullPointerException.

The stacktrace doesn't point to any of the custom code (what I've written).

Following is the stack trace...

Kindly help me.

Arthi,

I am using TreebyNestingTableColumn in my present application, without any problems. Can you invalidate the table node before you re-fill it and see what happens.

Hi Raj,

Thanks for the reply. I always invalidate before proceeding to fill it up.

As I said, as long as the data (even one record is shown) comes up out of the search, it works fine.

After receiving the data, if at any point of time the search return is null, then it throws the above error.

Hi,

is this table nested in a couple of layout managers?

[former_member194668 · Accepted solution]

Hi Ayyapparaj,

Yes, it is inside a group (Grid Layout) of RootElement (Grid Layout).

That's a bug. Open an OSS message on component BC-WD-JAV-RUN.

Hi Armin,

I'll try to open one.

Thanks for the suggestion.
