Re: [WDSCI-L] Radio Button Troubles

[Mike Hockings <hockings@xxxxxxxxxx>]

The cheap solution would be to simply put a try-catch around the if 
statement as if it is blank then it ain't an 'X' ! 

<%try{if(SCRN01.getFieldValue("SELPO").charAt(0)=='X'){%>SELECTED<%}}catch(Throwable
 
t){}%>

Otherwise you could check to see if the field is non-blank before getting 
the first char.

Re: [WDSCI-L] Radio Button Troubles






That worked but when I added the same thing for the other button when I 
come
back to the screen I get the following:

 javax.servlet.ServletException: String index out of range: 0
It seems to have a problem with with one of the values being blank.  Any
suggestions?
