Hi there,
I saw that if I have errors and warnings under the Problems tab, like below:
And then switch to Advice tab:
And at last switch back to Problems view, the errors and warnings had disappeared!
I can only get back my errors and warnings after I click somewhere on my project or the text editor:
I have checked the Configure contents menu, the scope says"on any element in same project". Because I have got only one project, I think this behavior is a BUG... I have also checked eclipse's behavior for switch between Problems tab to another tab, and switch back, but the errors and warnings is still there...
