B4J Question [SOLVED] [ABMaterial] No Sidebar Icon for Mini Template?

[incendio]

Hi guys,

I have follow the sample from this thread

[ABMaterial/ABMServer] Mini Template for absolute beginners (update 2022/09/08)

Hi all, Since the lockdown everywhere, a lot of B4X users seem to want to learn ABM to make WebApps in B4J. That is great! :) However, some seem to struggle a lot to get started. I understand, as even opening up the template can be quite overwhelming with those Cache, Root, Page etc classes...

www.b4x.com

Sample can run OK, but when tried to add an icon to sidebar which these codes

Sub ConnectNavigationBar(page As ABMPage) 'ignore
    ' Clear the dummies we created in BuildNavigationBar
    page.NavigationBar.Clear
    
    ' add the menus to your sidebar
    ' examples
    page.NavigationBar.AddSideBarItem( "About", "About", "mdi-action-dashboard", "../ABMPageTemplate")
        
    page.NavigationBar.Refresh ' IMPORTANT
End Sub

The item is displayed but the icon didn't.

Is this normal or there is something wrong with my codes?

Works fine here. The only thing I can think of is that you are running it in Release mode before running it at least once in Debug mode: this is needed because icons are put in the .needs files in debug mode as in Release mode, the source code is not available to find which icons you used. So, also when deploying, do not forget to copy the .needs files next to the jar!

Ran in Debug mode, got error, something about access denied to Template.jar.

Ran again in Relase mode, no errors, and worked as expected

Thanks for the hint.
