Disable a radio button in a radioGroupItem

[nicotik]

Hello,

I would like to disable a specific radio button in a radioGroupItem object. The method "setValueDisable(Object value,Boolean disable)" allows to do that normally, but I can't find how use it. This code returns me a fatal error :

RadioGroupItem groupItem = new RadioGroupItem();
groupItem.setValueMap("radio 1","radio 2");
groupItem.setValueDisabled("radio 2", false);

The begining of returned error is :

com.google.gwt.core.client.JavaScriptException: (TypeError): self.setValueDisabled is not a function
fileName: http://localhost:8888
lineNumber: 3 etc...

Someone have an idea of the problem?

Thanks a lot

What version of smartgwt are you running?

[nicotik]

I run Smart GWT 2.1, the last release.

Currently RadioGroupItem.setValueDisabled(..) can only be called when the DynamicForm that it belongs to has been drawn. For now you can add the line of code
groupItem.setValueDisabled("radio 2", false);

within a DynamicForm.addDrawHandler(..).

Thank you for your aswner sjivan.
Do you know if there is a way to make invisible a radio button?

After one year and with update SmartGWT 2.4 this problem seem to persist yet.
Even with the following code

aDynamicForm.addDrawHandler(new DrawHandler() {
  @Override
  public void onDraw(DrawEvent event) {
      groupItem.setValueDisabled("radio 2", false);
  }
})

seems not not work.

Inspecting ISC_Form.js we can see the groupItem.setValueDisabled(value,disabled) calls itemForValue(value).
Well, groupItem.itemForValue(value) refers to this["_radioItem" + value]; (where "_radioItem" in the minified wersion is "$540" string) but, with firebug, this not contains "_radioItem" + value element.
I've force the item to be isc_RadioItem0 to force the setValueDisabled to call isc_RadioItem0.setDisable(false).
Moreover, analyzing the call stack the radioGroupItem.update seems to put all inner RadioItem's disabled status equals to the radioGroupItem.disabled status.

Using 3.0

for me it is working if you call redraw() once in onDraw handler.

By the way: Would be nice to support API to use on initializing of SectionItem.
Calling redraw after setting disabledValue in addDrawHandler seems not correct to me.

My code looks like the one above.

We've made a change that should resolve this - now calling 'setValueDisabled' before (or after) draw is supported, with no need to call redraw.
This will show up in the 3.1d and 3.0p branches going forward.

RE The request about hiding a radioItem: this would typically be handled by just calling 'setValueMap()' and changing the set of visible options.

RE SectionItems: We're not sure what you're asking for here. There's already SectionItem.setDisabled(...). Is that not behaving as expected for you? Can you post a test case that demonstrates the problem you're experiencing?

Nice, thanks for enhancing API for us !

I meant RadioButton instead of SelectItem, so everything is fine!
