my app has nstextfields input; purposely not use nsnumberformatter in order special handling of input. app implements "full screen" mode. when app in full screen, , focus in text field, , press esc key resume windowed mode, instead pop-up spelling suggestions/completions. don't want either of these behaviors when esc key pressed: completions pop-up, nor not being able exit full screen mode. suggestions? thanks. you need setup nstextfielddelegate handle command, , set delegate on textfield. here's example: @property (weak) iboutlet nswindow *window; @property (weak) iboutlet nstextfield *textfield; @end @implementation appdelegate - (void)applicationdidfinishlaunching:(nsnotification *)anotification { // insert code here initialize application self.textfield.delegate = self; } - (bool)control:(nscontrol*)control textview:(nstextview*)textview docommandbyselector:(sel)commandselector { if (commandselector == @selector(canceloperation:)) {

in organization have decided use kieserver running drools. not using kieworkbench, because need more control on deployment , should aligned related application. ask externalize condition check. for example in rule below, check "2008" stored in database when $customer:customer(membersince <= "2008") $customer.setofferpercent("50%") i have figured out way value 2008 database/inmemory cache implementation , change below. allow operations/business change such values without deployment in kie server , reduce lot of efforts when $customer:customer(membersince <= cache.get("member_since_elite")) $customer.setofferpercent("50%") my question is, there other way declare global , auto populate values when changed in database. hoping below using annotations, , need help. declare properties member_since_elite : string @property("member_since_elite") end when $customer:customer(membersince &l
