Opera Browser issue in JavaApplet Mode (Read 4795 times)

	Hello, I know you guys have stated that only IE and firefox are supported in javaapplet mode. Yet, when I test other browsers, such as Chrome, work as well. I just thought it might be worth mentioning that if you select some node in the diagram and then postback, accessing the selected objects server-side is not there for Opera as it is with other browsers. The selected item count always comes back as 0. I am not sure if you guys have plans on supporting Opera or not, but it might be nice:). In any case, if you do, this is an issue. Thanks, jay

	Hi Jay, Is postback done from the NodeSelected script you posted a few weeks ago, or through some other ui element? Stoyan

	Hey Stoyan, Here is the code: aspx: <body> <form id="form1" runat="server"> <asp:ScriptManager runat="server" ID="scriptmanager"> </asp:ScriptManager> <div style="width:600px; height:600px"> <ndiag:DiagramView runat="server" ID="diagView" AutoScroll="true" Height="100%" Width="100%" ClientSideMode="JavaApplet" > <Diagram AllowSelfLoops="false" AutoResize="RightAndDown" RouteLinks="true" /> </ndiag:DiagramView> </div> <asp:Button runat="server" ID="btnPost" Text="Post" /> </form> </body> aspx.vb: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not IsPostBack Then Dim onode1 As MindFusion.Diagramming.DiagramNode Dim onode2 As MindFusion.Diagramming.DiagramNode onode1 = diagView.Diagram.Factory.CreateShapeNode(10, 10, 25, 25) onode2 = diagView.Diagram.Factory.CreateShapeNode(50, 50, 25, 25) diagView.Diagram.Factory.CreateDiagramLink(onode1, onode2) diagView.Diagram.Selection.AllowMultipleSelection = True End If End Sub Private Sub btnPost_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnPost.Click Dim iCnt As Integer iCnt = diagView.Diagram.Selection.Items.Count End Sub Notice that icnt is always zero even if one or more nodes have been selected and you then postback by clicking the button. jay

	The problem is much worse than that The code that saves the diagram to send it to the server when doing postback is not executed at all under Opera, and for example if you draw some new items on the client side, they will disappear after postback. We'll investigate this as soon as possible. Stoyan

	This version should fix the Opera postback problem: https://mindfusion.eu/_beta/netdiag103beta.zip Opera does not allow accessing fields of Java classes from JavaScript, but only methods, so we have updated a few scripts that access fields to call methods instead. The changed scripts are a part of the assembly resources, and might require you to clean the browser and server caches again until the correct version appears... I hope that helps, Stoyan

	Hey Stoyan, I am getting a script error with the new dlls. It breaks on the following: function WebForm_OnSubmit() { MindFusion.onFormSubmitApplet('diagView', '_mfusion_diagView_Data'); return true; The error states 'Mindfusion' is undefined. I reset iis, deleted all of my temporary asp.net files, deleted all temporary internet files, and even rebooted. I still seem to get that error. I even created a new web app and referenced the new dlls but still get that script error. Below is my code, when I postback by clicking btntest I get the error: <body style="background-color:#CCCCCC"> <form id="form1" runat="server"> <asp:ScriptManager runat="server" ID="scriptmanager" AsyncPostBackTimeout="300"> </asp:ScriptManager> <asp:UpdatePanel runat="server" ID="up1"> <ContentTemplate> <ndiag:DiagramView runat="server" ID="diagView" AutoScroll="true" Height="500px" Width="500px" ClientSideMode="JavaApplet" > <Diagram AllowSelfLoops="false" TextColor="White" DefaultShape="Rectangle" AutoResize="RightAndDown" LinkCrossings="Arcs" RouteLinks="true" /> </ndiag:DiagramView> <ndiag:Overview ID="ovw" runat="server" DiagramViewID="diagView" Height="100px" Width="100px" /> <asp:Button runat="server" ID="btntest" Text="test" /> </ContentTemplate> </asp:UpdatePanel> </form> </body> This error also seems to be happening in all browsers.

	Have you also replaced the applet's .jar file with the one from the archive?

	Oh yeah. I definitely did that. I think it had something to do with this: http://dotnetslackers.com/JavaScript/re-57918_ScriptResource_axd_and_and_assemblies_built_in_the_future.aspx It seems if the dlls are compiled in the future, there can be problems. When I set the date on my computer to a future date, I no longer get the script error. Because you are in a different time zone than I, the dlls were compiled in the future. I think tommorrow everything will be working fine. I'll keep you posted. Thanks. jay

	yep, we've tried it from a past date and seems that's the problem; so you have solved this longstanding mystery
