InputField problem for negative currency value

Hi All,

I'm new to the forum and to SAP in general but I do have years of programming experience behind me. I'm working on a WebDynpro application that is monitoring promotional funds. The user at times may want to increase or decrease a fund. The initial fund value is stored in one table while all subsequent changes will be stored in another table. The user merely has to input the amount they wish to change the fund by whether it be positive or negative.

The problem is, when I input a negative value into the InputField (e.g. 25000-), my onEnter event gives me the error: "The Sign Is Invalid".

The data type is Currency and I can input negative values directly into the table using the Data Dictionary without a problem.

Any suggestions?
