%CSP.LogError %CSP.StudioTemplateError


• classmethod DisplayError(ByRef ErrorInfo As %String) as %Status
Output in HTML the error information in ErrorInfo which is the array provided by DecomposeError.
• classmethod HyperEventError()
If an error occurs while processing a HyperEvent then this method is called. This method will write out javascript code that will be executed on the browser. Note that the variable 'CSPPage' refers to the 'self' of the page on which the Hyperevent was called as this may be different to the current 'self'.

You could use this javascript to redirect the browser to another page:

	Write "CSPPage.window.location='/csp/samples/menu.csp';",!
Or you could popup an alert box with the error message in it:
	Write "alert('An error occurred');",!
• classmethod OnPage() as %Status
Output the error page as HTML. This makes use of the ##class(%CSP.Utils).DisplayAllObjects() call to display as much information as possible about the state of the %request, %response, %server objects when the error occurred.
