storeXPath() fails with version 2.6
-----------------------------------
Key: WT-408
URL: http://webtest-community.canoo.com/jira/browse/WT-408
Project: WebTest
Type: Bug
Versions: 2.6
Environment: Debian lenny on 2.6.24.3 Linux Kernel
JDK 1.6.0_10
Groovy 1.5.1
Reporter: Florent Blondeau
Attachments: jaxenexception.html, jaxenexception_test.groovy
I'm facing a problem that didn't appear with the last version I used (2.5)
I have a storeXPath() step (sorry for the method formulation, but I'm using
groooooovy) that works really well with the 2.5 version.
I use the same script with an other webtest path (which points to the 2.6)
My 53th step raise this exception (I put only the relevant information that
doesn't come from the webtest exception treatment):
<error exception="com.canoo.webtest.engine.StepExecutionException"
message="Unexpected exception caught: java.lang.NullPointerException">

]]></stacktrace>
</error>
It seems to come from Jaxen contains() evaluation within the xpath which is
storeXPath(xpath:
"//td[contains(child::text(),'Webtest')]/following-sibling::td[position()=2]/child::text()",
property:"webtest")
I've found something interesting. You can see the minimal html that rise the
exception attached.
There is an HTML comment line 20. If I delete this comment, the script doesn't
raise any exception and retreive the good value
Hope that helps to improve webtest ;-)
