ComboBox with Vaadin Grid and ComponentRenderer and the Empty Grid
I hope this post can help me.
My problem that when I use ComponentRenderer, then the grid appears empty.
The used vaadin version 7.6 and the used ComponentRenderer is 1.0.3 as it is recommended to be.
If I did not use ComponentRenderer, then the grid appears but the combo box is not appear.
What could be the reason?
Below is the used code:
Object itemId = container.addItem();
container.getContainerProperty(itemId,"ID").setValue("1");
container.getContainerProperty(itemId,"Dependent MPI").setValue("200.300");
container.getContainerProperty(itemId,"MPI Type").setValue("Antenna");
container.getContainerProperty(itemId,"Approval").setValue(ApproveReject);
this.getColumn("Approval").setRenderer(new ComponentRenderer());
Regards

Object itemId = container.addItem(); //1
container.getContainerProperty(itemId,"ID").setValue("1");//2
container.getContainerProperty(itemId,"Dependent MPI").setValue("200.300");//3
container.getContainerProperty(itemId,"MPI Type").setValue("Antenna");//4
container.getContainerProperty(itemId,"Approval").setValue(ApproveReject);//5
this.getColumn("Approval").setRenderer(new ComponentRenderer()); //6
I believe you are trying to add a column "Approval" in line 5. Shouldn't it be:
Column approvalColumn = container.addColumn(...);
approvalColumn.setRenderer(...);
