Error with @taskImage in main menu button

[Jeff]

I am trying to use the new feature to put a task image on the selected main menu button, but it causes GBPVR to crash with an unhandled exception for an object reference not set to an object error.

My skin file has this in it.

Code:

        <CompositeImage name="SelectedButtonImage" size="450,145">
            <DrawImage filename="..\resources\menu_list_focus.png" loc="4,5" size="208,32"/>
            <DrawText text="@buttonText" loc="15,9" size="200,34" textStyle="ButtonText" align="Left"/>
            <DrawImage name="@taskImage" loc="225,5" size="126,140"/>
        </CompositeImage>

And the gbpvr.exe.log file shows this error:

Code:

12/3/2005 5:55:29 PM.630    ERROR    [2]    Error: msg=0x18 (WM_SHOWWINDOW) hwnd=0x260a80 wparam=0x1 lparam=0x0 result=0x0  :  System.NullReferenceException: Object reference not set to an instance of an object.

This feature isnt widely tested, so I would be surprised if there is some bugs in there.

My initial thought was maybe its not gracefully handling the situation where a task returns a null task image? Check that all the tasks seem to have them. Maybe also try temporarily removing any plugins so you're testing initially a against a smaller set of task that could potentially cause this problem.

Everything had a task image, so just to be safe I removed and reinstalled GBPVR. since this is my development machine it has had all the GBPVR prereleases on it and I though maybe something was off. I also removed everything from the plug-ins directory and all taks other than the TV Guide. It still crashes. Can you post an example main menu skin that works? Maybe I have something wrong with my syntax.

Ok. I just tried it here. It works fine for the default plugins.

I just edited the .\skin\blue\mainmenu\skin.xml, and set the two button definitions to:

Code:

        <CompositeImage name="SelectedButtonImage" size="166,45">
            <DrawRoundedRect loc="4,5" size="155,30" radius="10" borderWidth="4" borderColor="White" fillColor="DarkBlue"/>        
            <DrawText text="@buttonText" loc="15,7" size="155,34" textStyle="ButtonText" align="Left"/>            
            [b]<DrawImage filename="@taskImage" loc="0,0" size="50,45"/>[/b]                
        </CompositeImage>
        
        <CompositeImage name="NormalButtonImage" size="166,45">    
            <DrawRoundedRect loc="4,5" size="155,30" radius="10" borderWidth="2" borderColor="Black" fillColor="DarkBlue"/>
            <DrawText text="@buttonText" loc="15,7" size="155,34" textStyle="ButtonText" align="Left"/>            
            [b]<DrawImage filename="@taskImage" loc="0,0" size="50,45"/>[/b]                
        </CompositeImage>

I had to change a couple of task images to make them show up though, since the default ones are mostly transparent, and far too large for this usage.
