Hello everyone, I have a problem with bbcodeview. The error is below:

B4X: 
Error occurred on line: 201 (BBCodeView)
java.lang.NullPointerException: Attempt to invoke virtual method 'anywheresoftware.b4a.objects.collections.List com.aam.us.crg.bbcodeparser._parse(com.aam.us.crg.bbcodeparser, com.aam.us.crg.bbcodeparser$_bbcodeparsedata)' on a null object reference

I already initialized the TextEngine before I add a text in BBCodeView. The error occurs in BBCodeView.Text

Hi Chris,
I'm having the same issue. How did you fix it?

I set the Engine inside the Activity_Create

B4X: 
    bcEngine.Initialize(Activity)    
    bbAccounts_Delete_CSV.AutoUnderlineURLs = True
    bbAccounts_Delete_CSV.Text = $"[url]Delete CSV File[/url]"$       'crashes here
    bbAccounts_Delete_CSV.Redraw

It seems this is the answer/fix to the issue I was having...

B4X: 
    bcEngine.Initialize(Activity)
    bbAccounts_Delete_CSV.TextEngine = bcEngine    'make sure you add this here
    bbAccounts_Delete_CSV.AutoUnderlineURLs = True
    bbAccounts_Delete_CSV.Text = $"[url]Delete CSV File[/url]"$       'will not crash now
    bbAccounts_Delete_CSV.Red
