After our upgrade to Tridion 2011, I was trying to convert Custom URLs code which are written on ASP on Tridion 2009. But in between I stuck with few API's are not available on Tridion 2011.

On **Tridion 2009**, below are working as expected:-

    window.dialogArguments.fieldValue
    window.dialogArguments.fieldType
    window.dialogArguments.isMultiValued
    window.dialogArguments.publicationURI

On **Tridion 2011**, I changed to below format but I didn't get values as expected. And also on **firefox**, I get few values and on **IE** I get values as `undefined`.

FireFox:
--------

    window.dialogArguments.getFields()[0].properties.fieldDefinition.localName = SingleLineTextField
    window.dialogArguments.getFields()[0].isMultiValued = Undefined
    window.dialogArguments.getFields()[0].publicationURI = undefined

IE:
--------
    window.dialogArguments.getFields()[0].properties.fieldDefinition.localName = Undefined
    window.dialogArguments.getFields()[0].isMultiValued = Undefined
    window.dialogArguments.getFields()[0].publicationURI = Undefined

Please suggest me on how to fix this.
