[Acceleo] Problem with String replaceAll [message #557182]

When calling the replaceAll service on a string I get the following error. I'm calling it like so:

getProperty('basePackage').replaceAll('.', '/')

I'm not sure if this has something with the getProperty method or what, but when I take out the replaceAll service the error doesn't happen. I'm setting the basePackage property string to "org.domain", so there should be a '.' to replace.

Thanks, here is the error:

I figured out that I had the properties set up wrong. All fixed now...

Hi,

Happy to see you fixed it, though your first post does point to an error
we need to fix in the core.

Could you raise a bug about the "replaceAll(..)" operation throwing an
exception when called on an undefined String?

Hi Tom,

What version of Acceleo are you using ? 3.0 or 3.1M1 ? You can see it in "Help -> About Eclipse -> Installation Details -> Plugins"
And for your bug, well I think I solved it with another bug few days ago that was similar, because I can't reproduce it in my developement version so the fix should be available in Acceleo 3.1 and Acceleo 3.0 SR1 or SR2.
