Index of class on empty string

[CinnamonMetal]

I'm hung on a problem, with python.  hou.ui.readInput() produces a tuple; I have a while loop but I can't get the index item of the tuple which is the "OK" button of the class not to disappear if the string is empty ?

In other words, if the user clicks "OK" the dialog should not disappear.

Not clear what are you trying to do. Post your code example here so I could help.

nodeName = hou.ui.readInput("what do you want",buttons=('OK',"Cancel"),default_choice=0,title="Name the sphere",close_choice=1)
if nodeName[0] == 0 and nodeName[1] !="":
    intro = hou.node("/obj").createNode("geo","geometryA")
    superGeo = intro.createNode("sphere",nodeName[1])
    superGeo.setPosition([2.3,4.5])
    superGeo.setParms({"radx":2.3,"radz":4.2,"type":"bezier","rows":54})
    fileNode = hou.node("/obj/geometryA/file1")
    fileNode.destroy()
    superGeo.setRenderFlag(True)
else:
    while not nodeName[0] == nodeName[0]:
        hou.ui.displayMessage("You must supply a valid node name")
        break

while True:
    btn, nodeName = hou.ui.readInput("what do you want",buttons=('OK',"Cancel"),default_choice=0,title="Name the sphere",close_choice=1)
    if btn == 0 and nodeName:
        intro = hou.node("/obj").createNode("geo","geometryA")
        superGeo = intro.createNode("sphere",nodeName)
        superGeo.setPosition([2.3,4.5])
        superGeo.setParms({"radx":2.3,"radz":4.2,"type":"bezier","rows":54})
        fileNode = intro.node("file1")
        fileNode.destroy()
        superGeo.setRenderFlag(True)
        break

I one more question. 

How do I get the "OK" button to loop repeatedly if strictly the "OK" button is pressed ? I'm hacking away at this and I hope, that I solve this before hopefully your reply.

Do not use break keyword inside the if statement and you'll get an infinite loop.

If I make an infinite loop when the user enters some text instead of the rest of the script executing; the else statement is executed and the variable = nodeName does an infinite loop completely ignoring to execute the script ?  

I want the infinite loop strictly for the OK button, although not for the CANCEL button.
