How to wait for an object exists for till custom timeout?

Manish, this is one of the issues that bothered me as well. I don't like using .exists with mapped objects for that very reason. I've found that the Find method is significantly more reliable. Unfortunately, it doesn't have a built-in wait functionality either. So, I ended up writing my own wait function:

function waitWhile(condition, msg, timeout)
    dim t
    t = 0
    do While eval(condition) and t <= timeout 
        delaytext = t & " of " & timeout & " seconds passed waiting for " & msg
        delay 1000, delaytext
        t = t + 1
    loop
    if t <= timeout then 
        waitWhile = true
    else
        waitWhile = false
        log.event "Timeout expired waiting for " & msg
    end if
end function

 An example call to this would look like:

call waitWhile("aliases.pageObj.find(""name"", ""elementname"", 4, true).exists", "element to appear", 30)

 So this waits for up to 30 seconds for the object "elementname" to exist within for first 4 tree levels from pageObj. It will also change the indicator to say what it's waiting for (msg) and for how long. In the end, it returns a boolean for whether it hit the timeout period or not.

Hope this helps.
