RE: RE: Failed to invoke: Javascript function
Maybe there is a javascript error on the page causing problems. I don't see one in the browser. I've tried running the SL4 app in debug and non-debug modes but I get no extra information from anywhere, just the same Failed to Invoke error. No helpful diagnostic information is anywhere that I can find via any trick I can think of so far. Even if the JavaScript function doesn't exist I get the same error. InvalidOperationException is all I get and nothing else to help me, so it's not even getting as far as the browser. It's like a typical security roadblock, but there are no hints that it is one in this case. This is just a perfectly normal SL4 app with no weird things happening, it's just calls a WCF service to send XML back and forth and that's all working fine. I will now compare the html an scripts generated by the VS2010 wizard and my live ones.

RE: RE: Failed to invoke: Javascript function
HtmlPage.Window.Alert(Test); as per this thread http://forums.silverlight.net/t/211409.aspx/1 Alert works. I have spent another two hours trying to get the Invoke working. I looked back to June 2010 in version control to see who I did a similar testing technique then. I used GetProperty() to get a ScriptObject and then InvokeSelf. That code no longer works and I get null back from GetProperty. I have tried dozens of script functions signatures and nothing changes. I have moved the script to different places but nothing changes. I tried calling OnSilverlightError (the function generated by the wizard) and I get a different error Object doesn't support property or method 'getHost', but that gives me no clues. I also tried renaming my function to OnSilverlightError but I get no clues. So after 4 man-hours of trying to get any JavaScript function work (even an empty one) I only get the Failed to Invoke error and I have no clues. I only know that a fresh wizard generated SL4 app does Invoke okay and my real one doesn't. So here we are well into the 21st century in the age of science fiction and I'm still spending half of my working life trying to get hello world scripts to run. Even on mainframes I had core dumps to analyse, now I usually have nothing but sorry for the inconvenience. Silverlight, WPF, WCF and security blocks are fucking killing me, I'm wasting time, losing money and going mad and losing sleep, and this has been going on for years now with absolutely no sign that anything will improve. Oh well, now I will waste another hour up until 1:30am trying to get script debugging working in VS2010 (as John just suggested), but I'm sure if I do get it working (I thought it already was?!) then I will learn nothing and be right back where I started two days ago.
