Java – XPath for finding ancestor nodes containing CSS classes

I'm writing some selenium tests. I need to be able to find the ancestors of the webelement I've found

This is what I'm trying, but it doesn't return any results

// check@R_339_2419@ is also a WebElement
WebElement container = check@R_339_2419@.findElement(By.xpath(
    "current()/ancestor-or-self::div[contains(@class,'x-grid-view')]") );

The image below shows the dark blue highlighted div I selected and the one I want to point to with an arrow

Update tried prestomanifesto's suggestion and got the following error

[cucumber]       org.openqa.selenium.InvalidSelectorException: The given selector ./ancestor::div[contains(@class,'x-grid-view']) is either invalid or does not result in a WebElement. The following error occurred:
[cucumber]       [InvalidSelectorError] Unable to locate an element with the xpath expression ./ancestor::div[contains(@class,'x-grid-view']) because of the following error:
[cucumber]       [Exception... "The expression is not a legal expression."  code: "51" nsresult: "0x805b0033 (NS_ERROR_DOM_INVALID_EXPRESSION_ERR)"  location: "file:///C:/Users/JUAN~1.MEN/AppData/Local/Temp/anonymous849245187842385828webdriver-profile/extensions/fxdriv

Update 2 is really strange, not even ID

[cucumber]    org.openqa.selenium.NoSuchElementException: Unable to locate element:{"method":"xpath","selector":"./ancestor::div[@id='gridview-1252']"}

Update 3

The following XPath is effective but fragile

../../../../../../../*

Solution

This should select the element you want

./ancestor::div[contains(concat(' ',@class,' '),' x-grid-view ')][1]

In simple English: choose the first (closest) element among all ancestor div elements with 'x-grid-view' in their class
