Hi,

In webdynpro explorer open the project structure. in dictionary->local dictionary->simpletypes

right click and create a simple type. You can set the various parameters like minimum length ,maximum length, basic type etc. if you en you create an attribute give the property type as the simple type you created

the validations will be done when you perform an action in the view

Following your instruction on changing the type: my view context is map to a web services object and Web Dynpro would not allow me to change the type. Any thought?

Christian,

Then this is typical case for calculated attributes.

Say, you have model node MyWs_Request with model attribute MyParam of type string. You want to limit number of characters for MyParam attribute.

Create 1..1 non-singleton value sub-node MyWs_Request_Proxy as direct child of MyWs_Request node. In this node create attribute MyParam_Proxy with your custom simple type defined in Local Dictionary (sure, this custom type must have MaxLength restriction set). Make this attribute calculated and NW IDE will generate getter/setter methods. Fill in the following:

in getter:

final IWDNodeElement real = element.node().getParentElement();
return (String)real.getAttributeValue("MyParam");

in setter:

final IWDNodeElement real = element.node().getParentElement();
real.setAttributeValue("MyParam", value);

Now bind any InputFields to calculated proxy attribute. MaxLength restriction will be applied.

Josue,

To have the length limited in the browser you need to setup a simple type and set its maximum length to what you want. Then on the context attribute you have bound your input field to, set the type to the simple type you setup. When the html is generated it will include a maxlength tag for that input field and the browser will limit the entry to that number of characters.
