I am using GXT4.0 / GAE 1.9.28 / GWT 2.7.
I created a grid, one of the columns is a TextButtonCell.
Here is the code of the button column:
TextButtonCell bcDinamic_ = new TextButtonCell(){
@Override
public void render(com.google.gwt.cell.client.Cell.Context context, String value, SafeHtmlBuilder sb) {
super.render(context, value, sb);
}
};
bcDinamic_.setIcon(images.AspiEnTransito_24());
bcDinamic_.setIconAlign(IconAlign.LEFT);
colDinamic = new ColumnConfig<SerVisit, String>(new ValueProvider<SerVisit, String>(){
@Override
public String getValue(SerVisit visit) {
return visit.getEstatus() + "|" + (visita.isRequerirConfirmacionVisita()?"1":"0")+ "|" + (visita.isRequerirControlEntradaSalida()?"1":"0") ;
}
@Override
public void setValue(SerVisit object, String value) {
// TODO Auto-generated method stub
}
@Override
public String getPath() {
// TODO Auto-generated method stub
return null;
}
},180);
colDinamic.setCell(bcDinamic_);
configs.add(colDinamic);
I need to hide the button in some specific rows, according to its value.
I tried something like this:
@Override
public void render(com.google.gwt.cell.client.Cell.Context context, String value, SafeHtmlBuilder sb) {
if (condition){
super.render(context, value, sb);
} else {
EMPTY:NO BUTTON!
}
}
It seems to work fine, but once in runtime, everytime the cursor highlight the row comes a error message:
Error (TypeError): Cannot read property 'contains' of null
In GXT 2 it was very easy to acomplish this, but now in GXT 4 I cant find a way.
Thanks
