Selenium click() or isSelected() are not executed on RadioButton's input element - xpath

Question

I have radio buttons that are located inside a table, such as:
<tr id="radiofield-1080-inputRow">
<td class="x-form-item-body" id="radiofield-1080-bodyEl" colspan="3">
<input type="button" id="radiofield-1080-inputEl" class="x-form-field" autocomplete="off">
<label id="radiofield-1080-boxLabelEl" class="x-form-cb-label">My Label</label>
</td>
</tr>
I do find the input element, by the following code:
xPath = String.format("//tr/td[contains(#id,'%s')][contains(label,'%s')]/label", xType, text);
webElement = webDriver.findElement(By.xpath(xPath));
but isSelected() or click() doesn't seem to work on it.
Do you have any suggestion?

Answer 1

Haven't used selenium in a while but from a quick google it looks like you should try the isChecked and check/uncheck methods.
Here's the Javadoc but for some reason can't get a decent link, obviously check on the Selenium object. If you're using a different version or if I misunderstood something sorry.

Answer 2

In your code snippet problem with locator.
Use any of the below below locators
By.cssSelector("input[id*='radiofield-']");
By.id("radiofield-1080-inputEl")
By.xpath("//tr/td[contains(#id,'radiofield-')]/input")

Answer 3

Try clicking on the "input" instead of the "label".
xpath of input:
"//input[#id='radiofield-1080-inputEl']"
If the input id is not always the same, you can try this, the location of input will be based off the label:
//label[text()='My Label']/preceding-sibling::input

Answer 4

Thanks for all your answers.
My finding concluded with the following:
ExtJS implement radiobutton and checkbox as button, therefore the selenium isSelected() is not functioning.
There is a need to implement isSelected(), as suggested at:
How to check if extjs checkbox is selected in selenium?
The click() does the work, as it is a button.
