OIM GTC Custom Transformation Provider Issue

 Hi Oracle, 

I have some issues about custom transformation provider.

 

Q. I see the Custom transformation provider in the drop-down menu. But when I am selecting the Custom provider it is showing blank page, I am not able to see the input fields.

 

I have property file. (SubStringTransformation.properties)

1. ###### Transformation Provider ######  
2. gc.provider.TransformationProvider.SubStringTransformation=SubStringTransformation  
3. GC.GCPROV.TransformationProvider.SubStringTransformation.REMQUOTES_INPUTSTR_MISSING=Input String Missing  
4. GC.GCPROV.TransformationProvider.SubStringTransformation.REMQUOTES_INPUTSTR_MISSING.description=The input string is missing.  
5. gc.TransformationProvider.SubStringTransformation.Input.label=Input  
6. gc.TransformationProvider.SubStringTransformation.Input.description=Enter Input  
7. gc.TransformationProvider.SubStringTransformation.beginIndex.label=beginIndex  
8. gc.TransformationProvider.SubStringTransformation.beginIndex.description=Enter beginIndex
