Error when receving int from Pure Data via OSC

simorlabrasse

Hello

I'm new here, I am compositor artist/tool developer for Nuke and Maya. I work in Berlin and I'm discovering the fascinating world of real time and interaction withs images :D

I'm trying control my processing sketch with Pure Data. It works very well with floats, but if I want to receive a string or a int, it doesn't work and display this error :

[2015/10/20 21:47:21] ERROR @ OscP5 ERROR. an error occured while forwarding an OscMessage

to a method in your program. please check your code for any possible errors that might occur in the method where incoming OscMessages are parsed e.g. check for casting errors, possible nullpointers, array overflows ... . method in charge : oscEvent java.lang.reflect.InvocationTargetException

The weird thing is that even if I receive float, if I received for example 1.0, I get this errors. Did you ever seen something like that ?

this is my code : of course, when I try to receive int or string, I change the oscEvent function :)
