Using custom keyword in custom keyword

This is not supported yet. Actually a custom keyword is presented as a function, so you just call it directly using method call, e.g:

@Keyword

def isElementPresent(TestObject to, int timeout){

//Use Katalon built-in function to find elements with time out 1 seconds

List elements = WebUiBuiltInKeywords.findWebElements(to, timeout)

//Call getHtmlTableColumns custom keyword

getHtmlTableColumns(null, “”)

return elements.size() > 0

}
