Simple Type Format Validation

Question

Hi,
I have a simple type Buil-In Type double with External Representation->Format as follows: "$ ###,##0.00"
My attribute is binded to an Inputfield and the data is presented correcty, for example "$ 2,000.00".
But my problem is when the user wants to change that value and gives for example "1000" on that same Inputfield, on any action the framework is validating that the input data is in incorrect format, and the user has to enter explicit the format with the currency symbol "$"...
Is there a way I can avoid this validation?
I do want the framework to validate if the value is a Build-in type double and showed as currency on screen, but let the user the capability to enter any number without the format with the sign "$"
Is this possible???
Thanks in advance.

Hi Alan,
You can use the concept of calculated attribute for achieving this. Create a calculated attribute based on this attribute.
Once the user enter something in the input field and some action is called by framework, the caculated setter method will be called and then  you can change the format in which ever way you want.
A calculated attribute is an attribute that is not stored by the element, but calculated each time the attribute is accessed. Therefore it must be marked in the IDE and controller methods must be declared.
Calculated attributes can have getters and (unless they are read only) setters. The getter calls the declared controller method with the following signature:
                      AttrClass getNodenameAttributename(NodenameElement element);
It is expected to calculate and return the value based on other values of the element.
The setter is only generated if the attribute is not marked read only. It has the following signature:
                      void setNodenameAttributename(NodenameElement element, AttrClass value);
This method is expected to modify other attributes of the element based on the given value. It does not mark anything changed by itself. Only the modification of other attributes leads to updates of the GUI.
(The above method names are proposals of the IDE. You may change them.)

No need to remove the validation code. That is actually a good feature provided by the framework. Why to remove that?
I hope that helps!! Please revert back in case you have further issues.
