FilterDelay given as "integer" causes NullPointerException

[klopc]

Using dt:filterDelay="10000" will cause a NullPointerException in TableFilterDelayAttrProcessor as it will try to cast the given value, an int, into a BigDecimal.

(from AttributeUtils.processStandardExpression at :
return result == null?null:(clazz.isAssignableFrom(result.getClass())?result:null);

Workaround is to use : dt:filterDelay="10000.0" which will work correctly, but is unintuitive and does not correspond to the documentation.

An easy fix would be to replace line 28 of TableFilterDelayAttrProcessor :
BigDecimal attrValue = (BigDecimal)AttributeUtils.parseAttribute(arguments, element, attributeName, BigDecimal.class);

with :
BigInteger attrValue = (BigInteger)AttributeUtils.parseAttribute(arguments, element, attributeName, BigInteger.class);
