Interface ISelectModel

All Known Subinterfaces:

IEnhancingSelectModel

All Known Implementing Classes:

DynamicSelectModel, StringSelectModel

public interface ISelectModel

Same as IPropertySelectionModel in Tapestry 4.x. Implementations of this interface are used to create html-presentable ways to select one (or many) objects from a collection of objects. How this works:
First the ISelectModel is used to render a set of <option> tags. (pseudo code)

 for (int i=0; i < selectModel.getOptioncount(); i++) {
      <option value="selectModel.getValue(i)">selectModel.getLabel(i)</option>
 }
 

When a form is submitted with the value from the selected option tag, its then translated to the selected object with a call to translateValue(valueFromFormSubmit);
