Displaytag not WSRP compatible - Dynamic url parameter causes WSRP rewrite to
fail, generates invalid portal url
----------------------------------------------------------------------------------------------------------------
Key: DISPL-595
URL: http://jira.codehaus.org/browse/DISPL-595
Project: DisplayTag
Issue Type: Bug
Components: Container Compability
Affects Versions: 1.1.1
Reporter: Dale
Portlet is being provided by a WAS 6.1 server and consumed by Websphere Portal
6.0 via WSRP. Using spring portlet MVC and displaytag 1.1.1.
Issue is that all renderUrls generated by displaytag that append a parameter to
the url are invalid and can not be encoded by the container. When you click on
the link the portal server will redirect you to the landing page (navigational
state is not preserved in the url). The same code will work without issues in a
non-WSRP environment (everything running in portal container).
This is the code that will generate urls that cant be encoded with WSRP:
<portlet:renderURL var="myUrl">
<portlet:param name="action" value="detail_page"/>
</portlet:renderURL>
<display:table name="searchResultList" sort="external" defaultsort="1"
pagesize="10" class="display_table">
<display:column property="myObject.myObjectId" href="${myUrl}"
title="foo" sortable="true" class="display" />
</display:table>
This is the error thrown when the container tries to generate the urls:

This is the invalid (non-encoded) url that can't be parsed by portal when you
click on it:
http://localhost:10078/wps/myportal/!ut/p/c1/04_SB8K8xLLM9MSSzPy8xBz9CP0os3ingBCnMEdPY0N_IxNTAyO3sGAzVyMzAwN3Q6B8pFm8n79RqJuJp6GhhZmroYGRmYeJk0-Yp4G7izExunHJGxgQ0B0Oci1-20HyBjiAowFEHo_9fh75uan6BbmhEQaZAekAgMbcIA!!/dl2/d1/L0lDU0NTQ2xDbElKSmdrS0NsRUEhL29Kb1FBQUlRSkFBTVlwQ2pJTXhqbk1RRkpVbENrQSEhL1lCSkp3NDU3Rl9ONDUwLTVENGtzcnludy83X0JQVEJWQUkzMU8yNDUwMkZWUzZFMjYwMEgyL3ZpZXcvbm9ybWFsLzFvWjpJMTY0L3dzcnAtaW50ZXJhY3Rpb25TdGF0ZS9NVEoyTVRFeE1UWmhZM1JwYjI0eE1VRXhNVEl4Tlcxa1psOWtaV0ZzWDNObFlYSmphQSoq/wsrp_rewrite?wsrp-windowState=wsrp%3Anormal&wsrp-secureURL=false/wsrp_rewrite&wsrp-urlType=render&wsrp-navigationalState=MTJ2MTEyMjEyc3VibWl0YnV0dG9uMTFBMTExNnNlYXJjaDE2YWN0aW9uMTFBMTEyMTVtZGZfaGVhZGVyX3NhdmU*&myObjectId=10001&wsrp-mode=wsrp%3Aview
A proper url should look something like this (page and sort links work, oddly
enough):
http://localhost:10038/wps/myportal/!ut/p/c1/hY3LcoJAEEW_JV8wzdNhCchjwgADAkE2FEFFiIOUBlLx68VKVqmQ9F11nXvroALN6aupbar39txXJ5SjQi0dx8eet5EAh3gFog1RxOIUAEsz36plEIqpLRNBwKolgKi6skEzAs5a-mf98vD9vX9wWDgdvviSwRFR4J75Hm1RsVpsuQJKUA5yuelg8Om1929ayBJfIUmthJ_XkglN7Q1jU_GBVzzsuAp1RQ4-1Uw_eDv0NnHV8Zg7Y_zKO9IYIOHWQvnU7j9-mMFYa7M509MIZ_Mrf7d-8VNLCah1CVurpDfz9Ex3lO2yODV004wnBmjgObTseJE4eboD94HH2w!!/dl2/d1/L0lDU0lKSmdvS1VRIS9JSFNBQ0lpTXlDb3FiRUFvSUEhIS9ZQTQ1NDUwLTVGMHN0eWp3LzdfR0dNOEtLUzMwMEJEOTAyRlZBVVE4VjMwMDQvdExXN28xNzYvZmlsdE1zdHJJZC81NQ!!/#7_GGM8KKS300BD902FVAUQ8V3004
As a workaround, I have had to create the links in the controller and then pass
in on the display binding object and use the displaytag "Value" property to
render in the jsp...this way there is no chance that displaytag mucks around
with the url. I can't even get scriptlets doing the same thing using
object_rowNum to create the renderUrl to work. I do not have this issue
anywhere else in the application so I suspect that displaytag is doing
something non-orthodox when it comes to generating these urls.
This is probably an issue with the order or manner in which displaytag is
appending the parameter to the url which prevents the portal from being able to
encode the wsrp part of the url properly. I would like to get this fixed and
contribute to the project but am not sure where to start looking. Please advise.
