Table with StyleProvider

Support
#1

Hi
I’m using Cuba Platform Studio 6.10.2 and platform-6.10.7

I need to conditionally format same cells in a grid.
I followed Cuba documentation and tis is my code:

public class Tab1Browse extends AbstractLookup {

@Inject
private Table<Tab1> tab1;

@Override
public void init(Map<String, Object> params) {
    tab1.setStyleProvider(new Table.StyleProvider<Tab1>() {
        @Nullable
        @Override
        public String getStyleName(Tab1 entity, @Nullable String property) {
           // omitted code 
           return null;
        }
    });
}
}

I costantly receveive an NullPointerException error when the screen is open.
I don’t know how to resolve this issue.
Can someone help me?
Thank you

Hi!

It seems you try to inject wrong table id. In the layout you use tab1sTable:

<table id="tab1sTable"
       ...>

so in the controller you should use following code:

@Inject
private Table<Tab1> tab1sTable;

@Override
public void init(Map<String, Object> params) {
    tab1sTable.setStyleProvider(new Table.StyleProvider<Tab1>() {
        @Nullable
        @Override
        public String getStyleName(Tab1 entity, @Nullable String property) {
            return null;
        }
    });
}
