How to avoid special charecters in create user form

I BPE, "allowed values" property,i browsed and choosed isAlpha rule. In the isAlpha rule i mentioned global.firstname instead of "teststr"its throws the below mentioned exception

ERROR:Couldn't find method setAllowedValues(int) in class com.waveset.ui.util.html.Text ==> java.lang.NoSuchMethodException: com.waveset.ui.util.html.Text.setAllowedValues(int)

Have i made any mistake in invoking the rule,please let me know.
