Check the value of the context attribute to which the "selectedKey" property of the drop-down list is bound.

Hi

I have used this code to check context value attribute of type string

wdContext.currentContextElement().get<context_element>().equals(null)

and also

wdContext.currentContextElement().get<context_element>().length()==0

but none of them is working.

Help !!

Thanks

hi ananda,

display the value of wdContext.currentContextElement().get<context_element>()

using

wdComponentAPI.getMessageManager.reportSuccess(wdContext.currentContextElement().get<context_element>())

before the check and see what is coming]

Hi

I have used your suggestion and found that it is returning null.So I checked with following code

wdContext.currentContextElement().get<context_element>().equals("null")

but still it is giving NullpointerException

Please help

Use

wdContext.currentContextElement().get<context_element>() == null
