In the eventlisting, clicking on an IP address and selecting 'Filter on this Target' will result in a crash (see backtrace below).

The crash is caused by the fact that in the created filter string alert.target.node.address is used instead of alert.target.node.address.address.

The attached patch fixes this.

Backtrace:
