WPC Web Pages Approval

Hi
     We currently have a working approval workflow for "Site Content Folder" ( Author -> Editor) but now we want to implement a similar concept in "Web Pages" Folder (Editor -> Admin) . We have same settings apart from the approval steps but nothing seems to work. When we click on a web page details box we cant see "submit for approval".
   After some web search i could find that some versions of WPC don't support Web Pages Approval.
   We are using the following version: KMC-WPC 7.01 SP8 (1000.7.01.8.1.20110131042600)
   1) Does this version support Web Pages Approval? If affirmative what can i be doing wrong ?
   Another Question related to Publish. Our editor role does not have permissions to Publish any web page , but he can still see the Publish button in the "Edit Page Toolbar". If he clicks this button the following exception appears:
com.sapportals.portal.prt.component.PortalComponentException: Error in service call of Resource
Component : com.sap.nw.wpc.designtime.Publisher
Component class : com.sap.nw.wpc.publisher.Publisher
caused by: com.sapportals.portal.prt.component.PortalComponentException: Cannot find JSP file: error.jsp
He does not really publish anything but he still have access to the button witch is probably causing this exception.
2) Is it possible to hide this Button from Editors? or i am missing a Error.JSP file that would tell the editor he does not have permissions to Publish.?
Thanks in Advance

Thanks Tobias.
I believe you are right. But from what i can read about WPC 7.3( Not the version i am using) it is possible to approve Web Pages now am i right? Currently if i publish any page ( even if all the content is approved) it will just reset all the content Approval Status (i would have to send every content to approval again).
Still looking for a answer on the exception error.
thanks

Web Page Composer (WPC) – Web page - Approval process

We have requirement with our web publishing environment where we want to stage the web pages for review before they are published for public. Currently, if you develop a web page in Web Page Composer ( WPC ) and click publish to review the content/layout. The page is published for public and included in TRex and can be searchable.
We thought KM Approval process will help resolve this issue. The approval process work very well with the u2018Site Contentu2019 where once author develop the content (article, paragraph etc.) and submit for approval in this case Editor (role). The content under site content folder is not published (not available for public) until approved by Editor.
This same approval process does not work on the Web Page folder. We have exactly same permission/ Service permission setup on the Web Page folder. Even though the u2018Approvalu2019 is turned on the Web Page folder it does not inherit the same to new web pages created or existing web pages in that folder. If we go and turn on the u2018Approvalu2019 on a page then we see a u2018Approvalu2019 button in WPC but when you submit the page for approval it pops up another screen with below message.
Confirm that you want to publish the page. A new version of the homepage will be created and, if appropriate, submitted for approval. Changes to pages not subject to approval are active immediately.
When you confirm this message nothing happens (no workflow kicks off).
I would like to hear if any one has tried the approval process on WPC web pages. If you are not using this process how you are staging the web page for review before publishing to public.
Thanks.

Hi Bertina,
We encountered the same problem couple days back in our environment. There is a SAP note (# 1294833) which details the issue but affected version indicated in this note is different then what we are on so we decided to create a note for SAP.
Below is SAP response for this issues
13.09.2010 - 08:52:12 CET - Reply by SAP
Dear customer,
I can confirm that the issue described in SAP Note 1294833 is indeed
present in EP 7.01 SP4 and is the reason you are currently experiencing
this problem.
Unfortunately, as outlined in the note, there is no workaround
available but our developers have advised me that the fix will be
included in the next patch for KMC WEB PAGE COMPOSER 7.01 SP04.
Hope this helps.

FPN (Federated Portal) and WPC (Web Page Composer)

Hi all,
We implemented various web sites based on WPC (Web Page Composer) and now we need to federate this instance with other consumer nodes.
I read on SAP 880842 note that it's not possible to federate WPC.
Is there any options to federate sites developed in WPC?
What can I do in this scenario?
Thanks!

Thanks again Marcus.
But we can't use this option because we'll loose the WPC structure... It will need to be rebuild all site navigations...
We are working now with WPC content mirror (copying content from one server to another).
But we still need some help. We need to automatic copy KM content. Can you help us in this case too?
I opened a thread at this link:

Access to WPC Web Pages by Anonymous Users?

Hello,
i want to give anonymous users access to Web Pages that were created with the Web Page Composer.
In did the following:
1. create the Web Pages,Site Navigation etc....
2. edited the permissions of the site: grant anonymous users Read Access.
3.included the site navigation into the navigation of the anoymous users
When i access the portal as anonymous users and try to open a Web Page, i get a logon screen for Authentification.
I think that there is a problem, that i didn't find any way to set the Authentification Scheme for these Web Pages to "Anonymous". This is the way it has to be done with other iViews.
When i am accessing the page with an authenticated users, i have no problem with displaying the same Web Pages.
Is there anywhere an attribute i need to set? Or is it currently not supported?
Regards,
Marcus

1. Configuration in PCD - go to Content Administration -> Portal Content-> Portal Content -> Web Page Composer -> Container iViews -> WPC
Default Containers. All of the iViews in this location should have the
"anonymous" authentication scheme. The next location which should be
checked is Content Administration -> Portal Content -> Portal Content ->Web Page Composer -> iView Templates. Again all of the iViews should
have the "anonymous" authentication scheme. The same applies to all the
templates which reside in Content Administration -> Portal Content ->
Portal Content -> Web Page Composer -> Page Layout Templates. Finally
check if all the pages which reside in Content Administration -> Portal
Content -> Portal Content -> Web Page Composer -> Page Layouts have the
"anonymous" authentication scheme.
2. Configuration in KM - make sure that all the pages, which should be
displayed to an anonymous user have in their permissions the Anonymous
Users Group.
3. Security zones - if you go to System Administration -> Permissions ->Security Zones -> com.sap.nw.wpc -> wpc -> no_safety and you open the
permissions of this object, the Anonymous Users group must be added in
the list.
If all mentioned objects have their setting as described and you still
experience problems (e.g. you see a browser dialog window for
authentication), the reason most probably is, that the KM is not
configured for anonymous access. A full description of the needed steps
is provided with note 837898.

Permissions Issue with displaying WPC web page

Hi All (and Eric Heilers!)
I created and published a web page using web page composer. I added the web page to an iView and in turn the iView to a role. I assigned the role to myself and I was successfully able to see the Web Page....all was well.
Next I created a new test user and assigned a bunch of roles to a user group (one of the roles contained the web page iview). The role doesn't render the web page inside of the iView for the test user. I have given the test user Read/Write and also resorted to giving the user Owner permissions in almost everything but still I cannot render the web page!! I have tried permission in Security Zones in page builder (no_safety, and medium_safety), i have tried in, Portal Content Directory and also tried adding the test user full control permission from within the Web Page Composer role at the web site owner level. Still nothing. At best I was able to render the little toolbar which contains 'Edit" and 'RSS Feed' options on the top right, but not the web page itself.
Any helpful hints, suggestions, tips greatly welcome.
Kind regards,
Tony.

Thanks for your reply Eric,
So I'm just going to step thru this with you,
Prerequisites:
URL generator service -> I do not want to make the web pages externally accessible yet.
MIME handler service -> Is active.
Procedure
1) CM Repository Manager (this is optional so I didnt do it)
2) Folder Structure (Check)
3) Global Entry Points (this is optional so I didnt do it)
4) Configuring Entry Points for iViews (this is optional so I didnt do it)
5) I have created iViews to display the Web Pages
6) I have given relevant permission in security zones. (This is also where you advised me to do it for com.sap.nw.wpc -> wpc)
7) Although optional I am using this strategy to create group for roles and iViews created in Step 5 above.
8) I have assigned the relevant roles and group to users.
9) I have defined permissions in the web content repository.
10) I haven't configured search for web pages
11) I haven't configured localisation for languages and regions.
12) I haven't done any performance optimizing.
Now, from this you can see why I feel like I have done all that is necessary so far.
Any further suggestions?
Also, is there a way to upload a html page to the Web Pages folder and just publish that instead of using the WPC layout? As I want to keep all the javascript and stylesheet information? *
Kind regards,
Tony.

WPC Web Page Composer Change Component Layout

Hi,
how can I change the component layout in a Web Page Composer template.
For instance, I want to change the fonts and color for the title in the "Teaser" form.
Or I want to change the color of the links and the font size in the "Link List".
I have already created a new Layout, but I can't see anything to change the CSS-Parameters for the component layout.

Karl,
To answer your question, you will have to create your own web forms and then drag and drop to the container of the page layout to have the page rendered in the required style. This involves you creating the xml and xsl files corresponding to the new webform and refering the style(present in your own css file) in the XSL file associated wtih the new webform. Not only that there are quite a few configurations to be done.
Refer to the following sdn help to create new webforms - http://help.sap.com/saphelp_nw70/helpdata/en/45/599b78b0aa3bdde10000000a1553f7/frameset.htm Hope it helps.

Indexing of WPC Web Pages

On SPS13...
Indexing of WPC content works fine in our dev system, but it is not working in the Production environment.
I am not seeing any difference between the setup of the WPC index.
Obviously, there are differences in TREX architecture.
I am not too sure what to look at to figure out this problem.
The info file output from the crawler shows that the pages were filtered by the resource filter, but it says this in the environment that works fine.
Does anyone have any idea what I need to look at?
Regards

Hi Eric
You could start the troubleshooting by using the standard crawler instead of the wpc-crawler on the system that isn't working.

Migration of an existing web site to Web Page Composer

Hello,
I am investigating the options and the feasibility of the migration of an existing web site to a Web Page Composer (WPC) site. The web resources of the site can easily be copied to KM and used afterwards in WPC containers. However, they can neither be integrated to the WPC site navigation nor edited through the WPC UI. For example, only WPC Web Page or Web Sites can be WPC navigation nodes.
Has anyone ever done or tried such a migration? Do you know where I could find a description (or the javadocs) of the WPC API? Any suggestions or hints will be much appreciated.
Thank you
Youlian Dimitrov

Hi Youlian.
If I understand correctly you have rebuilt only a few hundreds of the old pages using WPC forms. Did you do this manually or you have found a way of migrating them programmatically?
Yes, we did it manually for a two reasons:
1. short timetable;
2. 20 intranet sites with variety of used technologies and tools, styles, navigation structures.
Did you leave the rest of the pages as HTML (non-WPC) files?
Yes. But we imported them into KM.
Does it mean that you have implemented only part of the navigation structure through the WPC/portal navigation?
Yes and no.
Firstly, in our case it would be a bad idea to bring all legacy, sometimes cluttered, navigation structure to a new platform as is.
Secondly, keeping in mind that in a common scenario portal already has own top level navigation you should carefully decide how deep is your site navigation structure will be.
Finally, migration it is a good time for information architecture redesign based on standards and guidelines.
Assuming that you have adjusted properly the links to all resources, have you encountered any particular navigation or display issues following this approach?
I could remember two limitations concerning a navigation:
1. you should avoiding links to navigation nodes inside non-wpc html files, because in this case a target page opens without DLN;
2. first linked non-wpc html page, which placed outside wpc container, should be opened in new window.
As for design, all our display issues caused by inline styles within source html files.
Did you notice any noticeable performance degradation after the migration?
We didn't have any degradation of performance. However, it is highly individual and depends on your portal infrastructure.

Aliaksandr Zhukau

Links Web Page Composer

Hi!
How can i get the link of a page in web page composer.
I´m going to details of page and Settings - Properties - Access Links - Content Link. But when i use this link in "href" it show the page in full browser and i lost my area of masthead (that is in framework)..
Thanks

Hi Leo,
The direct access link for each WPC web page is dynamically constructed after you publish your site and assign the value of the site navigation path to your role folder property External Connector.
So to answer your question, you can not take the portion of the URL I indicated and derive the complete WPC page path as it depends partially on your role PCD path, and also the web page path in the KM WPC repository (i.e. <PCD_PATH_TO_PAGE_OBJECT> does contains a PCD path and a KM path to web page in the WPC KM repository).
Once you are able to get the correct access link of a WPC web page from its property Content Link, your should see the web page displayed within the entire portal layout framework you configured for your system (i.e. includes masthead, top level and detailed navigation).
Hope this clarifies a bit.
Best Regards,
Joseph

Approval in Web Page Composer

hi Gurus,
We are trying to use Web Page Composer and created some web pages, now we have enabled the approval process.
Once we submit for appoval, the approver does not get any notification/mail rergarding the approval.
How do we enable the notification/mail triggering part to the person who has to approve it.
Thanks in advance.
Kris

Hi Paul,
I am following the same document to implement the approval process for web page composer. When submit the wpc page for approval, its not going to the approers' UWL instead its getting published. End users are seeing the modifications on the wpc page.
Am I missing any settings on the system to enable for workflow on the wpc page?
P.S: I enabled approval process on the wpc page (settings->Approval->Enable Approval Process). After enabling the approval process, I see a button (Approval) coming up on the wpc page properties beside the "Publish" button in the design time. When I use this button to submit the wpc page for approval, the wpc page is not staged for approval.
We are on EP7.0 EhP1 SP4.
Please advice.

Cannot Add Approved App To A Web Page - App Does Not Show in the App Part Section.

Hi all,
I have successfully add an App from the SharePoint App Store to my SharePoint Site which was developed using SharePoint 2013. The added app was successfully Approved then when I try to add that app using the App Part to a web page I cannot Find it
in the App Part section. I looked in the Site Collection Features & Site Features I couldn't find the app to activate. I don't think I have done some kind of mistake. So then what else I have to do to add that App part to the web page.
Could someone try to solve this matter?
Thanks,
Regards,
Chiranthaka

First, are you sure the App contains an App Part? Not all Apps are written to have app parts. Second, did you add the app to the site collection from Add an App in the Site Contents page? Apps that are added and approved from the Store
are added to the App Catalog for the Web Application. You would normally add them to the Site Collection from there after they are approved.
