[java-dev] Re: experience with stockwatch anyone?

Ok, so i managed to do the first part (getting more info from the SE) myself (however, still have to compile it) but another problem is, I want to get the numbers hat i get in number boxes to use those numbers as a source for my composition. Apparently you have to create an outlet for that, but what should i write
	declareOutlets(new int[]{DataTypes.ALL});
this is alrteady there, but i now i only get <END> in a message box. What do I have to write to get a separate outlet for numbers?
Thanks in advance
