_sourcePage passed request parameter via Javascript is having some exception on
server side validation during getSourcePage
---------------------------------------------------------------------------------------------------------------------------
Key: STS-555
URL: http://www.stripesframework.org/jira/browse/STS-555
Project: Stripes
Issue Type: Improvement
Components: Validation
Environment: Tomcat 6.0.16,
jdk1.6.0_05,
Stripes 1.5b1.
Eclipse 3.3.2.
Windows XP.
Internet Explorer 6.0
Reporter: J G
Hi,
Currently having an error during validation with errors and calling the
getContext().getSourcePageResolution() in an ActionBean.. The exception trace..
Bad Base64 input character at 0: 47(decimal)
15:14:30,117 DEBUG ExecutionContext:150 - Transitioning to lifecycle stage
RequestComplete
15:14:30,117 WARN DefaultExceptionHandler:39 - Unhandled exception caught by
the Stripes default exception handler.
java.lang.IllegalArgumentException: Null input buffer
at javax.crypto.Cipher.doFinal(DashoA13*..)
at net.sourceforge.stripes.util.CryptoUtil.decrypt(CryptoUtil.java:188)
at
net.sourceforge.stripes.action.ActionBeanContext.getSourcePage(ActionBeanContext.java:249)
at
net.sourceforge.stripes.action.ActionBeanContext.getSourcePageResolution(ActionBeanContext.java:226)

This only happens after a first load of my page. I have an href that have an
image that has an onclick that triggers a javascript. Then in my javascript
function I have Ajax.Updater method
var params = 'initVar&id=' + nId
+ '&_sourcePage=\/bugMaintenance.jsp';
new Ajax.Updater( "",
"${pageContext.request.contextPath}/ctrlr/BugMaint.action",
{ method: 'post',
postBody: params,
onSuccess: successAddFunc,
onFailure: errorAddFunc
});
I know this might is not the clean way, but do you have any ideas what is
wrong? Or any suggestion how to do this via Ajax to pass the _sourcePage?
I tried to debug the source code of stripes. The problem is on the
ActionBeanContext.getSourcePage(). during the call to
CryptoUtil.decrypt(sourcePage), since I did not encrypt the _sourcePage which I
just tweaked and passed as request parameter during an Ajax call, the
processing throws a Null pointer somewhere inside the decrypting of the source
page.
Inside the decrypt(String) method of CryptoUtil, the Base64.decode(input,
BASE64_OPTIONS) returned null.
Thanks,
