question on the page source element

Hello

in 'source' at the point of the text box, what is the deffrenet between the options: "only when the current value in session state is null" and "Always, replace the value that exists in the session state.

Thanks in advance

Nasser,

This is an excellent question and understand the difference is essential to develop pages that use the way you want.

The Source of a page element attribute works in conjunction with the Type of the Source attribute. When you see a form displayed on the page element, she got its value using the method that is identified in Type of Source (and the associated Source attribute). Let's say your item on page 10, P10_PROJECT_STATUS text field, use the Type of Source SQL Query and the Source attribute is Select the status of the projects where project =: project. Assume that project is a component of demand that determines the projects and that it is set by the user somewhere earlier in the session. The first time that the user goes to page 10, item gets its value from the SQL query (because it has no value in session state yet). Suppose that the user decides to enter a new value in the editable field. That page has a Next > button that causes a branch on page 11, where the user can make additional choices and can also save the changes to the database, using among other values, the changed value of the item P10_PROJECT_STATUS. But then on page 11, the user sees something that does not look right and wants to return to page 10 to check or change something if the user used by the <> button what branches back to page 10. Now we have new page 10 in front of the user. Waiting for the user to see for P10_PROJECT_STATUS? The value obtained by the Source of the element, for example, the SQL query, or the value is modified, the user has typed in the last time the page was posted? Of course, the user expects to see the recently registered value, not the original value of the query. To get this behavior, attribute of the element Source used must be on only when the current value in session state is set to zero. Value of the element in the session state is not null, the value just entered so that the value is retrieved to fill in the text field on the session state page by the user. Now, say the user proceeds to the transaction and gets on page 11, and applies the changes to the database. At this point, you can have page 11 taking the user back to page 10 to start a new transaction. But maybe you want to display the page just the way it was shown originally with the value of P10_PROJECT_STATUS obtained by using the SQL query in the Source attribute of the element. It's easy, that the branch page simply must include a clear-cache directive either to page 10 in sound together, or for the P10_PROJECT_STATUS element more precisely. Anyway, when rendering page 10, the value of the element in the session state will be zero so the Source of the item query will be used to fill.

Now consider the case where the Source setting still, by replacing the value that exists in the session state is the best choice. Page 20 is a Contacts page of current project which can be reached in a parent tab. If page 20 has a screen in the form of text (saved state) point P20_PROJECT_MANAGER with the attribute Type of Source SQL Query and Source Select project_manager projects where project =: project, it's pretty clear that the posted project manager name should come from the current value of the project ID. With the help of the current value in the session state for P20_PROJECT_MANAGER would show an incorrect value if project had changed from page 20 has received for the last visit. So still, by replacing the value that exists in the session state would be the best choice for the Source in this case.

Hope that helps.

    Hello Michelle,.

    You have a virus, here's what you need to do. Download and install malwarebytes of: http://malwarebytes.org/products/malwarebytes_free, be sure to update before running a full scan. If you cannot run the program at all, you will need to download a few programs of this site: http://www.bleepingcomputer.com/combofix/how-to-use-combofix it, you should get back on track.

    Also, you may have a browser redirection problem. Go to your IE tools--> internet options--> Connections tab, then click lan setting and make sure that the only box to checked in it is automatically detect settings.

  • Metadata not added to the page source

    I spent hours to update each dialog box page darned on my site, which has versions of phone, Tablet and desktop.  Each page has its own title (which added to the source code), keywords and description (or are added to the source code.  I found that the metadata did not appear in the source when I began to submit to search engines and was immediately informed that my site has no description of metadata or keywords.  I went to the http://truehdfitness.com/site and seen my source code.  Not a single keyword or an anywhere.on description

    What the devil I'm doing wrong?  I could have created the code of metadata in a Notepad file and made a copy page for versions of html on my site, but I don't want Muse clear every time I do a little change on the site... so, how in the world to get to add keywords and descriptions to the source for pages?

    Thanks for your help!

    Deltombe

    Okay, I don't know what happened, but some of my pages stored metadata and some did not.  Whatever it is, I saw that hand over the information in the page properties box, save the site, and do an ftp transfer (after each page is set) is loading the metadata about the site.  There may be a workaround, but it works.

  • A Question on the Pages MPOOL Allocation

    Hello
    I have a question about the allocation of pages in MPOOL.
    I noticed that for BDB2.7.7, if there are open an environment with DB_MPOOL_PRIVATE, a block of memory will be awarded for cache MPOOL (size is N * PAGESIZE). Pages requested by the access method are allocated from this memory block important, no bunch of other memory is allocated for the pages. Allocated pages from and free of MPOOL are implemented by __db_shalloc and __db_shalloc_free.
    However, for BDB4.6.18, if it is open a DB_PRIVATE environment, it seems that this page requested by the access method are allocated from the memory of heap on request. I don't know if my interpretation is right or wrong, but if allocating memory on demand will cause decreased performance?

    Thank you!
    Woody

    Hey Woody,

    Change to use ordinary malloc / free for the memory management in a private (in DB 4.3, 2005) environment was an improvement in the net return. One of the reasons are that allocateurs system are more sophisticated than the code shared Berkeley DB used to use for managing memory (our code has improved in this area in the meantime).

    However, concurrency is the main victory: we previously locked the mutex for the region in which we allocate or free memory. This blocked other operations in addition to the memory management. When you use malloc and free, this is obviously not required, and most systems have a multi-threads available allocators who perform better than simple simultaneous load, single-threaded allocator.

    Also, note that Berkeley DB tries to avoid the release of most of the objects allocated in the regions: there are pools of free objects for the most part, that greatly reduces the load on the allocator.

    Of course, there may be situations where our code of simple allocation would beat malloc/free of a particular system: If you have results of performance indicating a significant difference, please let us know.

    Kind regards

    by "link for a user to verify progress", I meant like my boss who will not change anything, just to see how things work so far.

    You can create a user account for a profile of portal for your boss. This user must have the group membership of the administrator of the portal or content portal editors.

    This portal I build is intended to be open to all on the internet.

    All content on portal with PUBLIC access privilege will be open to visitors to your site (unauthenticated user). They will not connect.

    the connection will only be for the future directors of the content of this portal, so that they can manage and other things.

    They will require user accounts / profiles and access to all pages. They should have membership in the groups portal developers and administrators of the portal. In addition, they should have to Manage privileges for groups of pages, pages and objects of the provider. To do this, go to Portal Builder / administer tab / and use the portlet to change their profiles of Portal. Once it appears on the screen, click the privileges tab and now grant privileges to them accordingly.

    but there will be guests who will only watch and for these people O don't know what connection can be established or user =)

    If these customers simply to watch content that is accessible to the public they do need user accounts. They will see all the public marked content above.

    Those who have a user account on your portal are authenticated users. These users need to enter to enter the portal. Those who do not require it are called unauthenticated users.

    hope that helps!

  • Question about the fast display element

    I'm playing with the new features and have found something I thought was weird/unfinished. In the item Quick View, you can rearrange your html quite easily by drag-and - drop tags in other areas of the list and moves of a given element in the code. It seems quite interesting for those who have a little sloppy with Cut and Paste and/or are not really all that only familiar with the code.

    All this seems to work, except in tables well.

    I can't move a table tag related to a table in the quick view of the item. I do not understand is not able to move a < tr > or < td > out < table > which causes a few problems of validation, but that move a < tr > in the < table > reorganize your lines appear as obvious as well as usefulness goes. Only one < td > leaving the front of < b > all the way to rearrange the order of the cells also seems that it would be a "given".

    Was there a reason moving the table rows in the table or cells in the row is not possible within EQV or is supposed to be possible and I need to take a look at my cache or Pref?

    The tables are quite surprisingly complex considering the addition of colspans and rowspans in your way of thinking. I'm pretty sure that tables were left out of the thing slide / move because of this complexity and their rare use for page layout.

    This is a known issue that has been resolved in version 9 of the designer. I think that there is a service pack where the patch went to version 8.2. If you cannot or do not want to upgrade your designer then if you validate your form I can 'clean up' and send it back.
