Issue with opening a bookmarked page when the user is logged out
Hello All,
I faced an issue while trying to open a bookmarked page with OFBiz.
Suppose, the URL of this bookmarked page contains a parameter with multiple
values and the value may have space character. The query string in the URL
looks somewhat like this
"?categoryHierarchy=3%2FCompany+Catalog%2FBrowse+Root%2FCloths%2FMen%2F"&statusId=approved&statusId=created".
The "%2F" and "+" are encoded value of "/", a separator and space
character respectively. The status id parameter appears twice and the
category hierarchy value has space character.
The user is logged out at this instance and this bookmarked page is opened.
Since the user is not logged in, the login page is rendered. I feed in the
credentials and the intended URL is hit. Here, I do not get the required
result.
When I check the URL, the parameter with multiple values just has the last
value of the list and "+" is encoded into "%2B". The URL now is
"?categoryHierarchy=3%2FCompany%2BCatalog%2FBrowse%2BRoot%2FCloths%2FMen%2F"&statusId==created."
I did some digging and found out that LoginWorker.checkLogin() comes into
action and what it does is that it creates a new session object (because
the previous session becomes invalid) and in the session object, it puts
the previous URL parameters. This previous URL parameters are fetched using
UtilHttp.getUrlOnlyParameterMap(request) which internally calls
getQueryStringOnlyParameterMap(). This method returns a map by breaking the
query string into key and value pair. A map can not have duplicate keys (in
this case removes the approved status) and the value is not decoded before
putting it into the map ('+' is not decoded). This map is then used to
create an encoded ('+' is encoded into '%2B' ) redirect target and then
callRedirect() is called on this new redirect target, ending up with
unintended URL (inside RequestHandler.doRequest()).
I could resolve this issue by decoding the already encoded value before
putting it into the Map and if the key is already present in the Map, it
must create a list of the values.
Am I missing something or is this really a bug and needs to be addressed
OOTB?
If this is a bug, is proposed solution the right one?

Re: Issue with opening a bookmarked page when the user is logged out
Posted by Michael Brohl <mi...@ecomify.de>.
OFBiz handles multiple request parameters with the same name well if you
use POST requests.
For GET requests, there seem to be no standard for multiple parameters
with the same name, see [1]. I thinks it would be good to investigate
further and see if we can fix this.
I don't see a problem with REST here, the data will most probably
transferred in some kind of JSON structure.

Re: Issue with opening a bookmarked page when the user is logged out
Posted by Taher Alkhateeb <sl...@gmail.com>.
Hmmm, based on Girish's feedback I think perhaps the next step should be to
open a JIRA and further investigate. Thinking about it some more, maybe
this would have an impact on the REST API project we're working on.

Re: Issue with opening a bookmarked page when the user is logged out
Posted by Girish Vasmatkar <gi...@hotwaxsystems.com>.
Hi Ritesh
It does look like an issue to me.
I believe (correct me if I am wrong) it is not so much about whether GET is
appropriate here, it is more about that the framework is unable to handle
multiple request parameters with same name, which is a common case when we
talk about multiple check boxes on a form representing a single entity. The
fact that GET is doing it's job correctly when the user is logged in (means
when you change the method from POST to GET and the user is already logged
in) and not so much when the user is logged out and the request is made via
bookmark, shows that the code is not working properly.
Then, there is also an issue with URL encoding and decoding that becomes
apparent with executing your scenario. Whether it is correct to change the
form method is arguable, but the code should be able to handle it. If a
form were to be designed with GET method and the only elements present on
the form are two check boxes and a text field and if you were to select
both check boxes and have value with spaces in the text box, this scenario
would still fail.
I think the simplest approach would have been to just store query string
(request.getQueryString()) in the session attribute instead of Map (but I
think it was well pondered upon to use Map) and then just redirecting to
the saved URL once the user loges in. I did it on my local workstation and
it just worked perfectly. May be one reason why a map was used instead of
storing query string was to handle unencoded requests coming from browsers
such as IE. I may be wrong so please correct me if anyone has an idea
around this piece of code as to why Map was used instead of storing the
query string in session to be used later on.
If you can do something to fix the existing code, that would be better
approach, IMO.
May be it is not a major issue but certainly worthy of having a dedicated
JIRA for. Everybody, please chime in and provide your thoughts.
Thanks and Best regards,
Girish Vasmatkar

Re: Issue with opening a bookmarked page when the user is logged out
Posted by Taher Alkhateeb <sl...@gmail.com>.
Okay, I understand this issue. I don't think it is possible to
abstract away a complex search screen with http GET method for
bookmarks. The performFind service is quite complex and it is
difficult to replicate the requirements using GET. GET is not designed
to handle multiple languages, spaces, and other peculiarities that are
needed for such a screen to work.
There are multiple solutions that I can see here. One of them is
simply to create a new entity, let's call it SearchFilter, that saves
search parameters, which can be applied later on. Either way, you need
to customize, your problem is not OFBiz, your problem is http GET
limitations.

Re: Issue with opening a bookmarked page when the user is logged out
Posted by Ritesh Kumar <ri...@hotwaxsystems.com>.
Using the POST method does not append form data to the URL, i.e, the
parameters will not be visible in the URL.
For example, take a Find Screen (say, FindWorkEffort) which send data
through a form with POST method. Apply some filters (say, status). No
applied filters appear in the URL. Bookmark this page. Next time when I
open this bookmark, those applied filters will not be there as this page is
being rendered using data from the URL and since the applied filters were
not there in the bookmarked URL, this page is rendered without the applied
filters. That is why I used GET form method so that I am able to get the
page with applied filters when I open a bookmarked page.
The bug here is (supposing the GET method is used)
1. On opening the bookmark, the page is rendered with double encoding (if
the value had a space character initially, the space character was already
encoded into '+' in the URL and when this bookmark is opened, this '+' is
again encoded).
2. Suppose the bookmarked URL had multiple values from the same filter
(say, Cancelled and Declined status), it renders with just one of the
statutes applied. It is because the request handler prepares a Map of
parameters from the query string and as is the property of Map to replace
the old value if a new value is being added with the same key (in this
example, first Cancelled status is put in this Map and then Declined), only
Declined status is put in this Map.
Hope, this clears the confusion. I will be happy to provide more
information if needed.

Not enough information. What happens exactly? What is the bug? What do you

Re: Issue with opening a bookmarked page when the user is logged out
Posted by Ritesh Kumar <ri...@hotwaxsystems.com>.
Hello Taher,
Changing form method to GET is just to make the query parameters visible in
the URL so that a user is able to bookmark or share it. Using the POST
method does not let us do that.

Re: Issue with opening a bookmarked page when the user is logged out

Just to put my point more clearly, let me add the steps to generate the
above-mentioned case. Please refer demo-trunk
<https://demo-trunk.ofbiz.apache.org/webtools/control/main>.
1. Open this link, FindWorkEffort
<https://demo-trunk.ofbiz.apache.org/workeffort/control/FindWorkEffort>.
Find Work Effort screen will be rendered.
2. Inspect and change the form method to "GET".
3. Apply any of the two statuses (say, Cancelled and Declined). Click on
Find.
4. Records will be fetched according to the applied filters.
5. Check the URL. Cancelled and Declined statuses must be there in the URL.
6. Bookmark this page and log out.
7. Now, open the bookmark.
8. The login page will be rendered. Check the URL here. It will be the same
as it was when the page was being bookmarked.
9. Type in the credentials and log in.
10. The result may be different. Check the URL. One of the statuses is
gone.
Due to business requirement, I need to show query parameters in the URL so
that the user is able to bookmark the page. And, we normally pass Id in the
parameters, but, due to some reason, I may have to pass values with space
characters.
I hope, this demo puts forth my concern.
