When I choose “Row Mapping” from the Edit Dataset dialog box I get this error:

What can be done? Is there a patch or am I doing something wrong?

What version of MyEclipse are you working with? Can you go to MyEclipse > Installation Summary > Installation Details and paste the information here for me.

mypaldave,
Thank you for bringing this up. I could replicate this at my end. I have filed a PR with the dev team

[mypaldave]

Thank you Shalini, any idea of when I can expect a fix?

Or is there perhaps a workaround I can do in the meantime?
