NPE periodically

[jimpil]

HI all,
I'm using the latest IDEA (community) and the latest cursive plugin (0.1.16). Every time I type something I get the following NPE...Idea doesn't crash and seems to continue to work fine, but the exception messages are rather annoying!

java.lang.NullPointerException

any ideas anyone? I 've spent a good 2-3 hours looking for a similar issue but was unsuccessful. Thanks in advance...

Hmm, this looks like you have a symbol defined somewhere in your project in a file with no namespace. Clearly you should be able to do that. By lucky chance, this bug is fixed in the next build anyway (no namespace now defaults to "user", which is what scripts do).

this is strange as I am opening a proper .ipr project and navigating to a particular namespace...in any case, it is good news that is has already been addressed.

I've got some news...it turns out that as soon as I load a file the NPE stops occurring. This morning I spent close to an hour without a single one. My guess is I should close this issue and wait for the update. Frankly, it wasn't a big issue in the first place since it's not leading to a crash of IDEA.
