Hi I have a very basic app in Titanium. There are 3 web views. When there is wifi from the start all three web views will load fine. I have a check in my code where the webview is only added if there is an internet connection. If there isn't, I add a label explaining to connect to the internet and a refresh button. When i click the refresh button, the adding of the web view crashES the app. Code works in iOS, not android. Using SDK 3.2.3. Code below:
refresh.addEventListener("click", function (e){
if(Ti.Network.online){
console.log(" here 1 -----------");
Navbar.remove(refresh);
console.log(" here 2 -----------");
self.remove(NoInternet_view);
console.log(" here 3 -----------");
self.add(shopWebView);
console.log(" here 4 -----------");
}
else{
alert("An internet connection is required");
}
});
The log gets to the printout "here 3 ----------" and then crashes.

EDIT: Code associated with map page:
var removeRefresh = function removeRefresh() {
if(Ti.Network.getOnline()) {
console.log("issue 1-------");
self.remove(NoInternet_view);
console.log("issue 2-------");
self.add(map1);
console.log("issue 3-------");
Navbar.remove(refresh);
console.log("issue 4-------");
}
else alert("An internet connection is required");
};
refresh.addEventListener("click", removeRefresh);
You are destroying refresh (Ti.UI.Button) in an anonymous handler.
You might try this code:
var removeRefresh = function removeRefresh() {
if(Ti.Network.getOnline()) {
Ti.API.info(" Checkpoint 1 -----------");
self.remove(NoInternet_view);
Ti.API.info(" Checkpoint 2 -----------");
self.add(shopWebView);
Ti.API.info(" Checkpoint 3 -----------");
Navbar.remove(refresh);
Ti.API.info(" Checkpoint 4 -----------");
}
else alert("An internet connection is required");
};
refresh.addEventListener("click", removeRefresh);
You must are secured of exist NoInternet_view and shopWebView.
Titanium Studio Console will show the four messages (Ti.API.info)
