InvalidElementStateException: invalid element state Error while using setText

Yes please , Thanks

@kazurayam
This is working for me now.
I used 2 objects.
td_Registration 1 : //td[(text() = ‘Registration 1’ or . = ‘Registration 1’)]
textarea_Input_Registration name : //div[4]/textarea

WebUI.doubleClick(findTestObject(‘path/td_Registration 1’))
WebUI.waitForElementVisible(findTestObject(‘path/textarea_Input_Registration name’), 10)
WebUI.setText(findTestObject(‘path/textarea_Input_Registration name’), “testRegistration”)

Thanks for your inputs, it really helped.
