Unexpected Error: executing JavaScript/Reference error - xpages

Question

I haven't made any changes to this database, and all of a sudden, I get an (500) error when loading various Xpages. On this one, when I switch to "Display the Xpage runtime error" on xpages tab of the database properties, it displays the errors below web.
If I remove the button that this Client side code is contained (it had worked perfectly to validate an Edit Box before), the error just moves to the next piece of JavaScript on the page and gives a similar error.
I've tried to "CLEAN" project. I've tried to Sign the entire database with the server id.
Any help would be much appreciated!
The runtime has encountered an unexpected error.

Answer 1

The script property of your executeClientScript action looks like it is being computed. The source should look something like this:
<xp:executeClientScript>
<xp:this.script>
<![CDATA[if(XSP.getElementById("#{id:ProjectTitle}").value == ""){...
]]></xp:this.script>
</xp:executeClientScript>
Instead, you have this:
<xp:executeClientScript>
<xp:this.script>
<![CDATA[#{javascript:if(XSP.getElementById("#{id:ProjectTitle}").value == ""){...
}]]></xp:this.script>
</xp:executeClientScript>
That syntax implies that, instead of simply entering client-side JavaScript to execute, you're running server-side JavaScript to compute what the client-side JavaScript should be. Server-side JavaScript does not define a global XSP object like client-side JavaScript does, which is why you're getting a ReferenceError.
Remove #{javascript: from the beginning of your CDATA block and the final } from the end, and your code will execute in the context you intended.
