List items do not refresh correctly.

In a form that i have developed there are two list items. I
want among others to chenge their appearance (background color
basicaly) according to witch one has th focus each time.
So I've put this code on the items, in WHEN-NEW-ITEM-INSTANCE
triger:
* LIST1
SET_ITEM_PROPERTY('LIST1',VISUAL_ATTRIBUTE,'SELECTED');
SET_ITEM_PROPERTY('LIST2',VISUAL_ATTRIBUTE,'GREYED');
* LIST2
SET_ITEM_PROPERTY('LIST2',VISUAL_ATTRIBUTE,'SELECTED');
SET_ITEM_PROPERTY('LIST1',VISUAL_ATTRIBUTE,'GREYED');
The Visual Attributes have the colors that i would like to
appear on the items.
This does not work (while it was working on Forms 5.0). It
seems to be a refresh problem, because when you open another
form that covers this one, or you minimize and maximize it the
colors are assigned corectly.
Thanks in advance for your help.

Hi Panagiotis Lygnos ,
I am not able to produce this problem. I create one form with
two list item ,two visual attribute & when-new-item-instance
trigger for these two list item as you have written above.
But List item background color of both list item is getting
changed according to witch one has th focus each time.
Even I tried to call this form from some other form still I am
getting correct result.
Can you just try by adding synchronize in the trigger of
both list item.
SET_ITEM_PROPERTY('LIST1',VISUAL_ATTRIBUTE,'SELECTED');
SET_ITEM_PROPERTY('LIST2',VISUAL_ATTRIBUTE,'GREYED');
Synchronize;
Bye

Large list items are not crawling

Recently we have migrated SharePoint 2007 application to SharePoint 2013. In that we are having a list which contains 40000+ items and each item have unique permissions set based on the business requirement.
After migration, we have ran full crawl on the web application. After the crawl, the list items are not crawled and displayed in the search results. When checked in the crawl log, there is no entry related to the list items.
Based on suggestions from the blog and microsoft we have changed the FilterProcessMemoryQuota and DedicatedFilterProcessMemoryQuota to 500 MB from 100 MB.
Still, the items are not crawled. Later we have modified some of the items in the list and ran the incremental crawl. The list items which are modified are crawled and available in the search results.
We have scheduled the incremental crawl to run on every night and full crawl to run every week end (saturday) night. What happened is the incremental crawl that run after full crawl deletes all the items which are modified and crawled before the full crawl
with a message "Deleted by the gatherer ( This item was deleted because its parent was deleted. )". This happens only with the incremental crawl run after the full crawl, but the subsequent incremental crawls add the items to the
search results until full crawl run.
Please advise on this.

40k items with individual permissions? That's going to have significant performance impact across your content database and is getting close to the hard limit(?) of 50k scopes per list http://technet.microsoft.com/en-us/library/gg128955(v=office.15).aspx
Having said that...
Your full crawl is picking up the items but the first incremental crawl is subsequently deleting them. Are you really using Incremental crawl or is this continuous crawling? Are all list items being deleted or merely some of them?
I'd normally put this down to the crawler not being able to identify the items, which may be the case here, but this sounds a little more interesting.

Login Window: Screen does not refresh correctly after waking 10.7.2 iMac and MacBook.

I have a client who brought to my attention that when we wakes his iMac and MacBook after the screen dims or sleeps at login screen, that sometimes the screen does not refresh correctly and you must use the cursor to basically "clear the screen." I have witnessed this myself and elimiated all third party products and this still happens. I am starting to believe that is is a bug in 10.7.2. Has anyone witnessed this or have any suggestions on how to remedy? Thank you.

Thanks lynque. It turns out I did need a keychain repair, but that didn't fix the problem. I probably should have done this earlier, but I ended up unplugging all peripherals (2 firewire + 3 USB) then powered up without issue.
So I shut down, plugged in one at a time, and ran into the problem again after plugging in an external hard drive (WD My Book Essential). I repaired with disk utility, but the problem remained.
I then rebuilt the partitions with Disk Warrior, and now everything seems to work....

Site Index Portlet is not refreshed correctly

I have deployed the Site Index Portlet in Portal 10.1.4, and it seems to work nicely. However, sometimes the portlet does not refresh correctly, even though other elements on the page (e.g. banner, page path) are updated. Refreshing the page with F5 in Internet Explorer 6.0 (or clicking the same link once more) refreshes the content of the portlet, but this is unacceptable for end users.
The same problem is not possible to reproduce in Firefox 1.5. If only all end users were using Firefox . . .
Any ideas for how to fix this for all browsers?

My browser caching is already set to "Every visit to the page", I'm afraid.
I was suspecting the PPE in Portal, but if that was the reason, then the problem would occur in all browsers, right? Or do you think this could be caused by how IE handles ESI?
Interestingly, the portlet works perfectly in Firefox (the menu is even updated immediately, before the new page loads!). And in Opera, the menu doesn't show up at all! What's going on here?

Cascading List Item does not work proprely

In HTMLDB 2.0
I have two list item
The first one: :P7_TYPE (select list with branch to page)
The second: :P7_PERIOD (select list)
The Query of the :P7_PERIOD use a where clause on :P7_TYPE
There is also two button at the bottom of region that will work once the two list (P7_TYPE and P7_PERIOD) are filled.
Note: Both Query are based on shared compenent LOV.
So I would like the page refreshed once the P7_TYPE values is choosed so the P7_PERIOD show only the valid values.
The problem is when I select from the P7_TYPE List, the page is refresh but instead of displaying the page 7 again, it display another page of the application.
I realise it always display the page number according to the value of the P7_TYPE.
For exemple, if in P7_TYPE is choose (type desc 4, value 4) then the page 4 is displayed.
I want the page 7 to be resfresh, not another page. So I can have a cascading list that work with P7_PERIOD.
??

Ok, I change the list for list with submit instead and it work.

Discoverer List of Worksheets not displaying correctly

We are having problems with the list of of worksheets portlet not displaying correctly every time.
Sometimes the portlet displays the the list of worksheets on a white background with all the grid lines missing, other times it displays correctly.
The portal is 10g and it is running over https, running over a load balancer.
Has anyone come across this before?
Thanks in advance

If you use a private connection then they should be able to see their own list of worksheets.

&ITEM. syntax not working correctly in logout_url

Hello all,
I have made my own logout procedure (which is part of a package) and am calling it from logout url as follow:
web_tool_authentication.logout?p_username=&APP_USER.&p_this_flow=&APP_ID.&p_next_flow_page_sess=&APP_ID.:1:&SESSION.
When I run the htmldb app, the &APP_USER. item is not correctly substitued in the logout url. It treats &APP_USER. as a literal value. This, however, is not the case for &APP_ID. and &SESSION. Does anyone know why this is occurring? Thank you for any suggestions.

The problem is that &LOGOUT_URL. is a substitution item that might itself contain other substitution items. We don't do recursive substitutions on that particular name, we just replace the occurrences of the commonly used items in a logout url. Perhaps APP_USER should be one of those, but it presently is not.

Hi,
The built-in cascading LOV does not work with a Multi-Select parent. It works only with single Select Items.
Multi-select items store a colon separated list of return values.
You will need to write your own DA to accomplish this requirement.
Note, even the WHERE clause in the child LoV will have to change for handling the colon separated values from the parent.
Cheers.

Cascading LOV in af:table will not refresh correctly

Jdeveloper version 11.1.1.5.0
I have spent quite a bit of time trying to understand why 2-level cascading LOV won't work in a particular situaion. I still haven't been able to fix it and so I turn to the ADF gurus on this forum.
Here's the scenario:
1. I have a ViewObject called AdjustDeltaValuesView. This VO contains attributes from its entity. It also has transient attributes called CategoryId and CodeId.
2. There is LOV defined for CategoryId for VO CodeCategoryMasterView
3. There is LOV defined for CodeId for LimitedCodeMasterView.
3. View Criteria is created for LimitedCodeMasterView which sets a bind variable value from CodeCategoryMasterView.CodeCategoryId.
4. I have wired all the LOVs correctly and it is working properly in ADF BC tester.
5. In the UI, I have dropped AdjustDeltaValuesView data control as ADF Table where CategoryId and CodeId are displaying as af:selectOneChoice.
6. CategoryId has autoSubmit=true and CodeId has partialTrigger set to component ID of CategoryId.
7. The LOV inside editable af:table is working fine except one scenario that when user selects same categoryId from the category LOV in the second row, the CodeId LOV will not populate.
Here's the code snippet of jspx:
        <af:table value="#{bindings.AdjustDeltaValuesView1.collectionModel}"
                  var="row" rows="#{bindings.AdjustDeltaValuesView1.rangeSize}"
                  emptyText="#{bindings.AdjustDeltaValuesView1.viewable ? 'No data to display.' : 'Access Denied.'}"
                  fetchSize="#{bindings.AdjustDeltaValuesView1.rangeSize}"
                  rowBandingInterval="0"
                  selectedRowKeys="#{bindings.AdjustDeltaValuesView1.collectionModel.selectedRow}"
                  selectionListener="#{bindings.AdjustDeltaValuesView1.collectionModel.makeCurrent}"
                  rowSelection="single" id="t1" editingMode="editAll"
                  rendered="false">
          <af:column sortProperty="CategoryId" sortable="false"
                     headerText="#{bindings.AdjustDeltaValuesView11.hints.CategoryId.label}"
                     id="c25">
            <af:selectOneChoice value="#{row.bindings.CategoryId.inputValue}"
                                label="#{row.bindings.CategoryId.label}"
                                required="#{bindings.AdjustDeltaValuesView11.hints.CategoryId.mandatory}"
                                shortDesc="#{bindings.AdjustDeltaValuesView11.hints.CategoryId.tooltip}"
                                id="soc3" autoSubmit="true">
              <f:selectItems value="#{row.bindings.CategoryId.items}" id="si3"/>
            </af:selectOneChoice>
          </af:column>
          <af:column sortProperty="CodeId" sortable="false"
                     headerText="#{bindings.AdjustDeltaValuesView11.hints.CodeId.label}"
                     id="c27">
            <af:selectOneChoice value="#{row.bindings.CodeId.inputValue}"
                                label="#{row.bindings.CodeId.label}"
                                required="#{bindings.AdjustDeltaValuesView11.hints.CodeId.mandatory}"
                                shortDesc="#{bindings.AdjustDeltaValuesView11.hints.CodeId.tooltip}"
                                id="soc4" partialTriggers="soc3">
              <f:selectItems value="#{row.bindings.CodeId.items}" id="si4"/>
            </af:selectOneChoice>
          </af:column>For example, where it DOES NOT Work
1. User selects Category A from dropdown from the first row.
2. code Id dropdown populates with corresponding values in the list based on CategoryId user selected.
3. user selects Code X from the dropdown.
4. User selects Category A from the dropdown from the second row.
5. PROBLEM: In the second row, Code Id dropdown does not populate. Code dropdown is empty.
Where it works:
1. User selects Category A from dropdown from the first row.
2. code Id dropdown populates with corresponding values in the list based on CategoryId user selected.
3. User selects Category A from the dropdown from the second row.
4. In the second row, Code Id dropdown populates correctly.
Where it works:
1. User selects Category A from dropdown from the first row.
2. code Id dropdown populates with corresponding values in the list based on CategoryId user selected.
3. user selects Code X from the dropdown.
4. User selects Category B from the dropdown from the second row.
5. In the second row, Code Id dropdown populates correctly.
Has anyone come across this scenario? It's a very weird problem.
I hope I have explained this well. If it's not clear please let me know.

Dynamic query built from items is not refreshing state

Hi. I'm generating a report table using the Pl/SQL function returns SQL query report region. My region source is:
declare
v_tbl varchar2(500);
v_sql varchar2(32676);
begin
v_tbl := v('P7_STUDENT_TBL');
v_sql := 'select b.grade,
b.lastname,
b.firstname,
b.middlename,
b.permnum,
a.student_attended,
a.parent_attended,
a.num_assoc_w_student,
a.ea_id
from event_attendance a right outer join ' || v_tbl || ' b
on ( lpad(a.permnum, 12, '' '') = b.permnum
and a.event_id = ' || v('P7_EVENT_ID') || ' )
where b.status = '' ''
order by b.lastname, b.firstname ';
return v_sql;
end;
As you can see, the query relies on a dynamic table name and event id. These 2 items are hidden items, although i've checked them and they are correct, as is the sql query supposed to generate the report.
It seems i have to go back and forth between the event page and this page in order for the report to "catch up" to the items (event id, table name).
It's almost like it's cached the old report, and won't discard it and bring up the current report unless the page is repeatedly accessed. There's no place to designate the source to be "Always, replacing any existing value in session state" like other items.
My dynamic tablename is accessing a remote database using a dblink. It's working, and shouldn't be remarkably slower, but i'm wondering why my report is not current with the items its using to generate the report?
I hope this is clear... any ideas?

Thanks for the reply, Scott.
I am indeed using bind variables in my query. The page before the "event attendance" page is "events" where you can search for an event. A link for attendance is there for each event record, which passes on the event id to the event attendance page, where you are recording the attendance for that event, which is for a particular school.
The query uses the event id and the school id in the query. The school table is dynamic, so i get the table's name from a function call. This query generates the list of students and some form elements for each student so you can record their attendance at an event.
Now i've verified that the table name, school id, event id, and even query are correct, by creating items i can see displayed on the page with their values. And the report is correct, but it seems a step behind.
For example, i may have an event for school 100. If i go back and select an event for school 200 to edit the attendance, my students are still from school 100. If i go back and select an event for school 300 to record attendance on, my students are from school 200. So you see, it's like the bind variables are hanging around. Yet if i look at the items (which are the same pl/sql source, but are items, not regions) they are correct.
My item query (which shows proper substitutions) is:
select b.grade,
b.lastname,
b.firstname,
b.middlename,
b.permnum,
a.student_attended,
a.parent_attended,
a.num_assoc_w_student,
a.ea_id
from event_attendance a right outer join schema.school015@dblink b
on ( lpad(a.permnum, 12, ' ') = b.permnum
and a.event_id = 91 )
where b.status = ' '
order by b.lastname, b.firstname
This item has EXACTLY the same pl/sql function returning sql source as the region, but it's an item, not a region. So what you see is the parsed query.

Dates not refreshed correctly

Hi,
We are using service contracts BT112H_SC from Web UI. From this component we are calling SAP GUI actions (using transaction launcher) to make changes to the contract u2013 like cancellations, date changes and so on.
We now have a problem with refreshing the Dates assignment block from service contract. The Dates assignment block is handled within a separate component called BTDATES and is called from BT112H_SC using component usage.
When running an action that should change the dates (due to for example an Annulation of contract), the status is set to Cancelled but the dates Contract end date is not changed. I am calling function module CRM_ORDER_READ_OW after the action is executed in some places and see that the dates are updated correctly in the buffer, but they are not showing up in the Web UI.
It seems as the dates are set correctly if I donu2019t expand the assignment block Dates before running the action. So if I expand the assignment block after running the action the dates are set correctly. If expanding the Dates assignment block before running the action, the dates are not updated.
The dates are also set correctly after saving the contract so it is just a matter of visibility.
Also if I (after running the action), go to one of the items and expanding the Dates assignment block on item level and then go back to header level the dates are displayed correctly.
I have enhanced component BTDATES/Dates u2013 Method DO_PREPARE_OUTPUT where I use the following commands that should refresh the values.
me->typed_context->btdate->collection_wrapper->publish_current( ).
lr_ent ?= me->typed_context->btdate->collection_wrapper->get_current( ).
lr_ent->reread( ).
I have also used the command modify without success.
Somehow the BTDATES component must be refreshed to read the dates from the buffer correctly after the action is executed.
Do anyone have any suggestions on how to handle this?
Regards Andreas

Hi,
Thanks a lot for your answers. I need all input I can get.
Kathirvel: I can see that event 0002_expand_link is triggered (from class ZL_BT112H_S_MAINWINDOW_IMPL I believe) when expanding the Dates assigment block. But I cannot figure out what is happening next.
But after expanding the assignment block once, the event is not triggered if I expand/collapse the assigment block again.
I see that in CL_BSP_WD_VIEW_MANAGER ~ DO_FINISH_INPUT when expanding Date assignment block, a BOL_CORE->MODIFY statement is made. This code is triggered when expanding the Date assignment block (but only first time).
Do you know which event I could call to trigger the update again?
asen2222 : I entered the code lr_core->modify( ) in ZL_BT112H_S_OVVIEWSET_IMPL ~ DO_PREPARE_OUTPUT which is called after my action is executed and the dates are modified in the buffer. But it doesn't work. When debugging the modify( ) method it seems as it have no delta-information to save.
I have also tried setting the statement in component BTDATES - ZL_BTDATES_DATES0_IMPL ~ DO_PREPARE_OUTPUT without success.
In the same place - component BTDATES - ZL_BTDATES_DATES0_IMPL ~ DO_PREPARE_OUTPUT - I also put the following code:
lr_ent ?= me->typed_context->btdate->collection_wrapper->get_current( ).lr_ent->reread( ).
This do not work either. But if I debug the reread method and go into
method REREAD_ENTITY of CL_CRM_BOL_CORE I see following code:
lv_relation_cacheable = me->object_model->relation_is_cacheable(
lv_parent_relation_name ).
If I then set lv_relation_cacheable = ' ', it seems to bypass the buffer and read the data from underlying layers. And then the values is showingcorrectly updated!.
I believe it is reading the relation from table CRMC_ORLSTA_BTIL but this
table do not include field DO_NOT_BUFFER so I assume this field should
never be set for business transactions. But in this case it wouldhave worked for us.
Regards Andreas

UWL do not refresh correctly when leave request change status

hi
I implemented the standar workflow of "Leave Request"(succesfuly), and the leave request appareced in UWL in MSS, I approved the leave request, but Leave Request is not change the status. But The employee of the leave request watch the new "status" with approved in the ESS option (Leave Request).
I refresh the UWL but Leave request stills appears with status "new", I clicked in the Leave Request (it had already approved in the previous step) and the new window open with error "index 0,0".
My questions are:
1. How I can refresh my UWL? and that I displayed the request approved
2. Why not change your status to approve the leave, if I do not get any error?
thanks for your post and answers
Ivan

implement the note 1501377 which was created to clear the leave request workitems
ensure it is done
and then following settings, In SWU3 schedule background jobs
in uwl administration you can set these
Default Execution Mode: Optimistic
Webflow User Format: Full Name
Default Cache Validity Period, in Minutes: 2
Maximum Number of Threads Created in the Thread Pool: 10
Timeout Value for the Connected Systems, in Seconds: 60
Please check how frequent you refresh your cache
1.,,Open task in the same window in the portal - rather than opening in
a new window when approving and rejecting tasks. This is so that the
actions will be controlled through the UWL UI rather than an external
window.
2.You can configure an additional column on the UWL UI called
isLaunched to mark an item that were already executed and may have been
completed already. This is very similar to the marked as read
functionality contained in an email client. If a user opens a task the
item will be marked as launched. If refresh happens either manually or
automatically then the workitem may be completed (marked as launched)
and disappears from the inbox. If it has been opened but not completed
the launched icon disappears.
3. Is Delta Pull enabled in your system?
Steps to clear the UWL cache
please go to "System Administration" "System Configuration" ->
-> Universal Work list & Workflow
-> Universal Workflow Administration
-> Click on cache administration page
-> Click "Clear Cache" button.

Windows and icons are black, menu items are not showing correctly

Hello!
Well just doing my normal routine today browsing the Internet, watching videos on vlc, my computer suddenly started to glitch. Icons were disappearing, Safari turned black.
So i did a restart but the problem is still there. I cant even choose the user properly because the avatars are not there it's just all dark gray. Remembering where my user avatar is, i do a click and type in my password and I do and able to get in to my system but all windows menu items and icons are black.
Basically what I'm saying is the system seems to be working fine except for that I can't see the icons and windows properly displayed.
I've already tried to reinstall of Mavericks hoping that it's a software thing. You guys think it's a problem with the graphic processor?
Any help or suggestions will be appreciated thank you.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It changes nothing, and therefore will not, in itself, solve your problem.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The procedure will help identify which such modifications you've installed, as well as certain other aspects of the configuration that may have a bearing on the problem. Don’t be alarmed by the apparent complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode, if possible. If you’re now running in safe mode, reboot as usual before continuing. If you can only boot in safe mode, you can still use this procedure, but not all of it will work. Be sure to mention that in your reply, if you haven't already done so.
Below are instructions to enter UNIX shell commands. The commands are safe and do nothing but produce human-readable text output, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects. I am not asking you to trust me. If you can't satisfy yourself that these instructions are safe, don't follow them.
The commands will line-wrap or scroll in your browser, but each one is really just a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. Step 1 should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click anywhere in the line of text below on this page to select it:
{ echo "Loaded kernel extensions:"; kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}'; echo $'\n'"Loaded user agents:"; launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)|\.[0-9]+$/{print $3}'; echo $'\n'"Inserted libraries:"; launchctl getenv DYLD_INSERT_LIBRARIES; echo $'\n'"User cron tasks:"; crontab -l; echo $'\n'"System launchd configuration:"; cat /e*/lau*; echo $'\n'"User launchd configuration:"; cat .lau*; echo $'\n'"Login items:"; osascript -e 'tell application "System Events" to get name of login items' | sed $'s/, /\\\n/g'; echo $'\n'"Safari extensions:"; /usr/libexec/PlistBuddy -c Print L*/Saf*/*/E*.plist | awk -F'= ' '/Bundl/{print $2}' | sed 's/\..*$//;s/-[1-9]$//'; printf "\nRestricted user files: %s\n" $(find ~ $TMPDIR.. $ -flags +sappnd,schg,uappnd,uchg -o ! -user $UID -o ! -perm -600 $ | wc -l); echo $'\n'"Extrinsic loadable bundles:"; cd; find -L /S*/L*/E* {,/}L*/{Ad,Compon,Ex,In,Keyb,Mail/Bu,P*P,Qu,Scripti,Servi,Spo}* -type d -name Contents -prune | while read d; do /usr/libexec/PlistBuddy -c 'Print :CFBundleIdentifier' "$d/Info.plist" | egrep -qv "^com\.apple\.[^x]|Accusys|ArcMSR|ATTO|HDPro|HighPoint|driver\.stex|hp-fax|JMicron|print|SoftRAID" && echo ${d%/Contents}; done; echo $'\n'"Unsigned shared libraries:"; find /u*/{,*/}lib -type f -exec sh -c 'file -b $1 | grep -qw shared && ! codesign -v $1' {} {} \; -print; echo; ls -A {,/}L*/{La,Priv,Sta}* L*/Fonts; } 2> /dev/null | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.
The command may take up to a few minutes to run, depending on how many files you have and the speed of the computer. A TextEdit window will open with the output. Post the contents of the TextEdit window (not the Terminal window) — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
Step 2
Remember that you must be logged in as an administrator for this step. Do as in Step 1 with this line:
{ echo "Loaded system agents:"; sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix\.cron)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; echo $'\n'"Login hook:"; sudo defaults read com.apple.loginwindow LoginHook; echo $'\n'"Root cron tasks:"; sudo crontab -l; echo $'\n'"Log check:"; syslog -k Sender kernel -k Message CReq 'GPU |hfs: Ru|I/O e|find tok|n Cause: -|NVDA\(|pagin|timed? ?o' | tail | awk '/:/{$4=""; print}'; } 2> /dev/null | open -ef
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
You can then quit Terminal.
To prevent confusion, I'll repeat: When you type your password in the Terminal window, you won't see what you're typing.
Note: If you don’t have a login password, set one before taking Step 2. If that’s not possible, skip the step.
Important: If any personal information, such as your name or email address, appears in the output of these commands, anonymize it before posting. Usually that won't be necessary.
Remember, Steps 1 and 2 are all copy-and-paste — no typing, except your password. Also remember to post the output as text, not as a screenshot.
Please post the contents of the TextEdit window, not the Terminal window.

Datagrid Item Renderer not displaying correct data

I have a datagrid that displays information from a web service, which is refreshed every 60 seconds.
When the status is no 0 for a line a corresponding color is used to fill in the background. I created a Item Renderer to fill in the background color.
When the table is initially created, the colors are correct. After the data is refreshed, then the background color value is carried over to the next row.
The Spark DataGrid works better than the MX AdvancedDateGrid or DataGrid. This was working in Flex 3, but I used an function which replaced the DataGridColumn that doesn't work in Flex 4.
protected function init(event:FlexEvent):void
                var showBackground:Boolean = false;
                var backgroundColor:uint = new uint();
                var labelTextColor:uint = new uint();
                var dgListData:DataGridListData = listData as DataGridListData;
                var dataGrid:DataGrid = dgListData.owner as DataGrid;
                // comment this out if you want to see the background over the
                // selection and highlight indicators
                if (dataGrid.isItemSelected(data) || dataGrid.isItemHighlighted(data))
                    // clear the background so you can see the selection/highlight colors
                    showBackground = false;
                    return;
                switch(data["MessageLevel"])
                    case 0:
                        showBackground = false;
                        backgroundColor = 0xFFFFFF;
                        labelTextColor = 0x000000;
                        break;
                    case 1:
                        showBackground = true;
                        backgroundColor = 0x00FF00; // light green
                        labelTextColor = 0x000000;
                        break;
                    case 2:
                        showBackground = true;
                        backgroundColor = 0x015F00; // dark green
                        labelTextColor = 0xFFFFFF;
                        break;
                    case 3:
                        showBackground = true;
                        backgroundColor = 0xFDFF00; // yellow
                        labelTextColor = 0x000000;
                        break;
                    case 4:
                        showBackground = true;
                        backgroundColor = 0x7F6E3F; // tan
                        labelTextColor = 0xFFFFFF;
                        break;
                    case 5:
                        showBackground = true;
                        backgroundColor = 0xFF8A00; // orange;
                        labelTextColor = 0x000000;
                        break;
                    case 6:
                        showBackground = true;
                        backgroundColor = 0xFFDFE0; // rose
                        labelTextColor = 0x000000;
                        break;
                    case 7:
                        showBackground = true;
                        backgroundColor = 0xFF0000; //red
                        labelTextColor = 0xFFFFFF;
                        break;
                if(showBackground) {
                    var bgFill:SolidColor = new SolidColor();
                    bgFill.color = backgroundColor;
                    dataContainer.setStyle("backgroundColor",backgroundColor);
                    lblData.setStyle("color", labelTextColor);

I added an "else" statement to make sure that a color was always added, even if the level was 0. I also added a backgroundAlpha style to both, to turn the value off or on.
So far, this seems to be the solution.
if(showBackground) {
var bgFill:SolidColor = new SolidColor();
bgFill.color = backgroundColor;
dataContainer.setStyle("backgroundColor",backgroundColor);
labelDisplay.setStyle("color", labelTextColor);
dataContainer.setStyle("backgroundAlpha",1);
} else {
dataContainer.setStyle("backgroundColor",backgroundColor);
labelDisplay.setStyle("color", labelTextColor);
dataContainer.setStyle("backgroundAlpha",0);

List items do not refresh correctly.
