Hi,
My component below is broken after I upgrade from Tap 5.1 to Tap 5.2
snapshot. In the component template FunctionInputWithSelect.tml, there is
Select component which gets all its parameters using inherit binding.
<td> <SELECT t:type="select" style="width:10em" t:id="mode"
blankOption="never"
model="model" value="value"
onchange="javascript:this.form.submit();">
</SELECT>
In FunctionInputWithSelect.java,
public class FunctionInputWithSelect {
@Parameter(defaultPrefix=BindingConstants.PROP, required=true)
@Property
private String function;
@Parameter(defaultPrefix=BindingConstants.PROP, required=true)
private SelectModel model;
@Parameter(defaultPrefix=BindingConstants.PROP, required=true)
private ValueEncoder encoder;
@Parameter(required=false,defaultPrefix=BindingConstants.PROP,value="literal:Compute"
)
private String buttonLabel;
@Parameter(required = true,principal=true)
private Object value;
@Component(parameters =
{ "value=inherit:value", "model=inherit:model",
"encoder=inherit:encoder" }, id="mode")
private Select select;
@Component(parameters ={ "function=inherit:function" },
id="functionInput")
private FunctionInput functionInput;
public String getButtonLabel(){
return buttonLabel;
}
}
In Tap 5.2, I get a null pointer exception.
