Element not visible sometimes with Robot Framework

Question

I am working with Robot FW for the first time and am facing an issue - one of the test cases requires a modal confirmation dialog to open, after which a button "Delete" is pressed. The keyword for the test case is given below:

Delete Test Data
    [Arguments]    ${name}  
    Wait Until Element Is Visible    xpath=//tr[@item_name='${name}']  
    Click Button    xpath=//tr[@item_name='${name}']//button[@class='btn btn-sm btn-danger']
    Wait Until Element Is Visible    id=deleteItem    timeout=10
    Click Button    Delete    
    Wait Until Element Is Not Visible    xpath=//tr[@item_name='${name}']

The line Wait Until Element Is Visible id=deleteItem timeout=10 is causing all the problems. Sometimes the element is visible within the time limit, at other times it is not. I increased the timeout to 10 seconds, but it does not fix the problem. How can I make the dialog appear each time without failing? Any help is appreciated, thanks!

Solution

My approach is to change the 'Wait Until Element is Visible' to Wait Until Page Contains Element like below..

${check_element}=  Run Keyword and Return Status   Wait Until Page Contains Element    locator    10s
Run Keyword If      '${check_element}' == 'True'     Click Element  locator

The reason to change to this keyword is that sometimes, the element is already loaded and available in DOM or page but the visibility is hidden. This intermittent weird thing happen to me some times.
