Taylor,

Add a validating action for the inputfield which would check if its numeric or not,

here is how to check,

public void checkIfNumeric( java.lang.String fieldName )
  {
    //@@begin checkIfNumeric()
	IWDMessageManager msgMgr = wdComponentAPI.getMessageManager();
	String fieldValue = wdContext.currentVaSearchFiltersElement().getAttributeAsText(fieldName);
	IWDAttributeInfo attributeInfo = wdContext.nodeVaSearchFilters().getNodeInfo().getAttribute(fieldName);	
	try{	
	Integer.parseInt(fieldValue);		
	}catch(NumberFormatException nfe){
		msgMgr.reportContextAttributeMessage(wdContext.currentVaSearchFiltersElement(),attributeInfo,IMessageSecurityReportComp.ROB__VER__NOT__NUMERIC,
		null, true);
	}
    //@@end
  }

In the fieldName - pass the context attribute name and modify the node and sttribute info as required..

Hi,

Create Context attribute and type is integer

and write the java code for numeric restriction

If the "value" property is bound to some numeric dictionary type, you don't need to write any validation code, this happens automatically.

Armin,

If you bind the attribute to a dictionary type, can you validate numbers wiht decimal digits e.g. 5.6?

Thanks

As Armin said, WebDynpro framework will validate the data types in the next server round-trip (if it is a validating action).

In the numeric dictionary data type it can be defined the number of decimal digits, so you can also validate it.

Hope it helps,

Use "float" or create your own DDIC type with built-in type "float".
