Description

Prior to upgrading our Tapestry 4.1.2 snapshot to one that required OGNL 2.7, this snippet found the listener and printed to the console:

.html:
<link jwcid="@DirectLink" listener="listener:theListener" parameters="ognl:

{index + 1}

">test</link>

.java:
public int getIndex()
{
return 2;
}

public void theListener(int idx)
{
System.out.println("listener called");
}

With the latest Tapestry and OGNL snapshots you get the error page and the below stack trace. Note this works fine without the "+ 1" in the listener parameters.
