It then returns. It expects its own filter to remain in effect until the compiler responds. Ordinarily this would be the case but in your case you invoke bsh-eval immediately after jde-compile returns. This reinstalls the standard bsh-eval filter before the compiler has a chance to respond, thus short-circuiting the compile-finish hook processing. I think the only reliable way to work around this problem is to do everything that depends on the compilation having finished, including a bsh-eval, in a jde-compile-finish-hook function. If you don't want your hook function to apply to every compilation, it could include a test for the specific cases that you do want it to handle, e.g., you could use a global flag variable, set the global variable before you call jde-compile and have your compile-finish hook function test the variable before it does anything. - Paul
