How do I get the location bar drop-down list to show the most recently visited page at the top? I have no idea how it's deciding what to display.

In IE when you show the drop-down list from the location bar, it show you all of your most recently visited pages in descending order with the most recent at the top. Firefox is showing me a list that I have no idea where it's getting the pages from or how it's ordering them. It doesn't update the pages or the order when I go to a new page. I have recently switched from IE to Firefox and cannot figure out how to get Firefox to do this; very annoying.

That drop down list doesn't show recently visited pages, but shows list list of most visited sites sorted by what the Mozilla devs call frecency (frequency and recency) and is based on bonus points. It is not possible to have much influence on what shows on that list.
If you want a list of recently visited sites then you can use a smart bookmark e.g. on the Bookmarks Toolbar with the location set to this smart folder.<br />
Name: <b>Recently Visited</b><br />
Location: <b>place:queryType=0&sort=4&maxResults=30</b><br />
You need to close and restart Firefox to make that folder work as intended.

Problems with populating Drop Down List (WD ABAP)

Hi,
I am trying to populate two Drop Down fields CARRID and CONNID (Type Table SPFLI) on an Adobe Interactive Form in a Web Dynpro ABAP Application.
In the WD Context I have a node "Flights" with those attributes.
In the WDDOINIT I populate the Context elements (just for test purposes with all entries of SPFLI).
[code]
DATA:
     node_flights                        TYPE REF TO if_wd_context_node,
     elem_flights                        TYPE REF TO if_wd_context_element,
     stru_flights                        TYPE wd_this->element_flights,
     it_flights TYPE TABLE OF spfli.
SELECT carrid connid FROM spfli INTO TABLE it_flights.
navigate from <CONTEXT> to <FLIGHTS> via lead selection
   node_flights = wd_context->get_child_node( name = wd_this->wdctx_flights ).
node_flights->bind_table(
    new_items            = it_flights
    set_initial_elements = ABAP_FALSE
[/code]
According to this
Re: adobe form/reader error I bound the element values property of the Enumerated Drop Down List to [code]$record.sap-vhlist.CARRID.item[*][/code], whereas <i>Object Text</i> is "Text" and <i>Object Value</i> is "Key".
Unfortunately the DDLs on the Adobe Form are not populated with the values read from the table. I debugged the application and the values are written to the Context node.
Do you have any further hints?
Best regards,
Robin

Problem with InputRender drop down lists

Basically, everytime i go through a particualar .particular, which initializes several View Objects for displaying various information to the system's user, in all my other .jsp forms, all the drop down lists that i create, loose all the data they should have displayed but one. That is, if they were to display 5 choices, they display only one of them.
Clearly this is something nobody wants, and i was wondering if anyone has come across this before and if yes, then what would you recommend to me to do?
Cheers for all you help

Make sure you upload your spry css file too.

Dynamic drop down list in jsp

Hi -
I have written a piece of code to dynamically include data in the drop down list after querying the data base. I can print the values using out.print().. but they do not show up in the drop down list. Below is the code -
Please lemme know the mistake i am committing. Thanks you!
<form name="browse" method = "POST">
<select name="uid">
<%
//out.write("before vec");
unit.setCid(user.getCid());
     Vector unitNumbers = unit.getUnitNumbers();
     ListIterator iter1 = unitNumbers.listIterator();
          while ( iter1.hasNext() ){
               Integer num = (Integer)iter1.next();
//               out.print(num.intValue());
//               out.print("Hellooooooooo");
%>
<options> <%= num.intValue() %>
<% }
%>
</select>
</form>

The correct tag should be <option value="val">Val</option>, like this:
<form name="browse" method = "POST">
<select name="uid">
    <%
      unit.setCid(user.getCid());
      Vector unitNumbers = unit.getUnitNumbers();
      ListIterator iter1 = unitNumbers.listIterator();
      while ( iter1.hasNext() )
        Integer num = (Integer)iter1.next();
    %>
    <option value="<%= num.intValue() %>"><%= num.intValue() %></option>
    <% } %>
</select>
</form>

How to display information from database using drop down list in JSP?

How to clear/delete drop down list of web pages visited?

When I type "www." in the address block, a drop down menu with a long alphabetized list of previously visited websites appears, going back for months. This list is not erased by Clear History or by quitting Safari. Is there any way to clear or delete this list for the sake of privacy? Thanks
iMac G5 Mac OS X (10.3.8) Safari 1.3.1 (v312.3.3)

I use OnyX and have it open at the moment so I can inspect the various panes while I make this reply. It will let you empty browser caches, including the ones for downloads, searches, form values, cookies, bookmark icons as well as the regular cache that holds urls.
In the Safari section, you can adjust the number of history items and the number of history items in the History menu. Unlike Safari Enhancer, there is no toggle to disable the cache. Most importantly for this topic, there is no toggle for Safari's url autocomplete.
Just clearing caches and history will not get rid of url autocomplete because autocomplete also uses your bookmarks, plus, the cache and history will refill as you use Safari.

The back/forward button no longer has a drop-down list of previous pages visited in that tab: or is this accessible some other way?

The question says it all, really. I just installed Firefox 4, and noticed a significant (for me) reduction in utility: in the previous version, the back button used to have a drop-down arrow which showed the previous pages visited in a particlular tab, and allowed you to go back several pages in one go, if you wanted to (say, when browsing a series of sites to buy something or other). Firefox 4 no longer has this facility, which I personally found very useful from time to time.
Is it available by some other means? If not, maybe I should consider reverting to the previous version, which suited me better, in this regard at least.

Just put the little arrow back into the system. Fix this now. I don't want 2 other options. Get this right for "nontech" people.

Drop Down list issues in jsp

Hi,
I am facing an issue with drop down list in jsp pages on page postback. Let me explain in detail. I have a client.jsp page which has a drop down list and a text box. The drop down list is populated from an Action class (lets say testAction.java). In the client action form class there is a validation which requires the user to enter some value in the text box.
So here is the problem, when the client.jsp page loads, the drop down list is populated perfectly, but then the user clicks submit button without entering anything in the textbox, the page loads again with an error message ("Please enter some value in the textbox"). At this point the drop down list does not contain any value. Any ideas what could I do?
I am posting the code here for individual pieces,
Struts-config.xml_
<action path="/client" type="com.myapp.struts.testAction" scope="session">
<forward name="success" path="/createClient.jsp"/>
</action>
<action input="/createClient.jsp" name="ClientActionForm" path="/createClient" scope="session" type="com.myapp.struts.ClientAction">
<set-property property="cancellable" value="true" />
<forward name="success" path="/loginSuccessful.jsp"/>
<forward name="cancel" path="/Welcome.do"/>
</action>
index.jsp_
<h5><html:link action="/client" styleClass="purplelink">Create a new client</html:link></h5>
testAction.java_
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
ArrayList<String> arrList = new ArrayList<String>();
arrList.add("sports");
arrList.add("music");
arrList.add("test 1");
arrList.add("test2");
request.setAttribute("mylist", arrList);
return mapping.findForward(SUCCESS);
createClient.jsp_
<select name="droplist">
<c:forEach var="itemName" items="${mylist}">
<option><c:out value="${itemName}" /></option>
</c:forEach>
</select>
<html:text property="clientName" />
ClientActionForm_
public ActionErrors validate(ActionMapping mapping, HttpServletRequest request)
ActionErrors errors = new ActionErrors();
if (getclientName() == null || getclientName().length() < 1) {
errors.add("name", new ActionMessage("error.name.required"));
return errors;
Here is the process/page flow.
index.jsp is the first page which is loaded.
Link on index.jsp calls action="/client"
This pulls mapping from struts-config and calls testAction.java
This populates the arraylist and returns to the createClient.jsp page (mapping from struts-config.xml)
Now createClient.jsp page has two fields (dropdown list and textfield=clientName) and a submit button
if user clicks submit, clientActionForm is called and does not enter anything into clientName text field, error message is returned.
At this point, the drop down list in createClient.jsp is not populated and is returned as empty, even though the scope=session in struts-config.xml
Please provide some inputs on how can I handle this issue.
Thanks
Ashish

I think one solution would be instead of putting the list in the request, but it in your ActionForm.
Add a field to the ClientActionForm with getters and setters.
Then change your action.
ArrayList<String> arrList = new ArrayList<String>();
arrList.add("sports");
arrList.add("music");
arrList.add("test 1");
arrList.add("test2");
ClientActionForm frm = (ClientActionForm)form;
frm.setMyList(arrList);
return mapping.findForward(SUCCESS);

Using getElementById() to get values from drop down list

Hi, I am using Netbeans to write this program. I have this .java page that gets the url of the HtmlPage from the .properties page. And when this page is opened in the browser, there are drop down lists that have values I want to get from the user when he/she has selected, and save it to a database. I'm actually using mozilla firefox to open this page, and using firebug to inspect the drop down list element.
I know getElementById is a javascript code, however, my friend told me to use it in the .java page. This is how part of my code looks like. What I'm not sure is how to implement getElementById() and where.
HtmlPage pageMain =EBPage;
WebRequest postRequestSettings = new WebRequest(
new URL(getProperties("trustAdmin")), HttpMethod.POST);
*// Set the request parameters*
postRequestSettings.setRequestParameters(new ArrayList());
postRequestSettings.getRequestParameters().add(new NameValuePair("component", "edit"));
postRequestSettings.getRequestParameters().add(new NameValuePair("formids", "unixTime,instance,time,description,message"));
postRequestSettings.getRequestParameters().add(new NameValuePair("page", "Status"));
postRequestSettings.getRequestParameters().add(new NameValuePair("service", "direct"));
postRequestSettings.getRequestParameters().add(new NameValuePair("session", "T"));
postRequestSettings.getRequestParameters().add(new NameValuePair("submitmode", "submit"));
postRequestSettings.getRequestParameters().add(new NameValuePair("submitname", ""));
*// Insert instance of message here*
postRequestSettings.getRequestParameters().add(new NameValuePair("instance", instance));
*// Insert content of message here*
postRequestSettings.getRequestParameters().add(new NameValuePair("message", message));
*// Insert description of message here*
postRequestSettings.getRequestParameters().add(new NameValuePair("description", description));
*// Insert time of message here*
postRequestSettings.getRequestParameters().add(new NameValuePair("time", time));
*// Convert time to unix seconds*
postRequestSettings.getRequestParameters().add(new NameValuePair("unixTime", String.valueOf(System.currentTimeMillis() / 1000)));
HtmlPage newPage1 = pageMain.getWebClient().getPage(postRequestSettings);
WebRequest requestSettings = new WebRequest(
new URL("http://www.google.com"), HttpMethod.GET);
requestSettings.setRequestParameters(new ArrayList());
requestSettings.getRequestParameters().add(new NameValuePair("page", "Preview"));
requestSettings.getRequestParameters().add(new NameValuePair("service", "page"));
newPage1 = newPage1.getWebClient().getPage(requestSettings);
And I'm told to insert page.getElementById() in the place shown below:
HtmlPage page = null;
page.getElementById()_
*try {*
*// Login proxy*
page = (HtmlPage) jsonBrowser.getPage(getProperties("jsonBrowser"));
String proxyUrl = page.getForms().get(0).getAttribute("action");
System.out.println("Proxy Url" + proxyUrl);
WebRequest requestSettings = new WebRequest(
new URL(proxyUrl), HttpMethod.POST);
requestSettings.setRequestParameters(new ArrayList());
requestSettings.getRequestParameters().add(new NameValuePair("PROXY_SG_PASSWORD", password));
requestSettings.getRequestParameters().add(new NameValuePair("PROXY_SG_PRIVATE_CHALLENGE_STATE", ""));
requestSettings.getRequestParameters().add(new NameValuePair("PROXY_SG_REQUEST_ID", ""));
requestSettings.getRequestParameters().add(new NameValuePair("PROXY_SG_USERNAME", userID));
*// Get the page*
page = page.getWebClient().getPage(requestSettings);
Logger.getLogger(postTrustMessage.class.getName()).log(Level.INFO, "===================================Login in Trust");
Logger.getLogger(postTrustMessage.class.getName()).log(Level.INFO, page.getWebResponse().getContentAsString());
*} catch (IOException ex) {*
Logger.getLogger(postTrustMessage.class.getName()).log(Level.SEVERE, null, ex);
*} catch (FailingHttpStatusCodeException ex) {*
Logger.getLogger(postTrustMessage.class.getName()).log(Level.SEVERE, null, ex);
return page;
Any help would be greatly appreciated. Thanks.

Drop-down list formattedValue returning value, not text

Hi all,
I'm having a problem with a drop-down list. I can get the information I want in Reader 9, but we only have Reader 7.0.5 distributed at the moment.
I need to pull out its text value and its specified value, but everything I try just pulls out the specified value.
In Reader 9 formattedValue gives me the text and rawValue will give me the specified value.
Anyone able to help me please?
Thanks,
Tom

Tom:
It's possible, but complicated. You need to look into the field definition where we store the listbox contents. Then you can correlate the display item from the bound item. I've done this before in another context. I've appended the script I used.

Infopath Drop Down List not showing all items in a list

I have an Infopath form where I have a vendor drop down and then I filter the product list based on the vendor. The problem is the drop down list is only filtering through the first 100 records. I added a second drop down with the model#'s and no filter and there is only 100 values showing. I checked the All Items view and it is set to display all records. Does anyone know how to fix this?

Hi all,
If I want a drop down list in InfoPath (data coming from a SharePoint list) to be in a particular order I query the SharePoint list via this method
http://blogs.msdn.com/infopath/archive/2007/01/15/populating-form-data-from-sharepoint-list-views.aspx
You can create a data connection to a particular view in SharePoint - make sure that view is sorted how you want it to be and the item limit is set to 9999.
You do not need code for this method and it works in browser enabled forms.
The people picker (which also works in browser enabled forms) http://metahat.blogspot.com/2007/05/people-picker-control-for-infopath-2007.html can help with those of you trying to get a list of users.
Cheers.

Refreshing drop down list in a web template based on a query view

Refreshing drop down list in a web template based on a query view
I have just developed my first set of portal pages displaying the results of Bex queries and query views in the SAP Netweaver portal. I developed the pages using web application designer. Each web template created with W.A.D is using a query or query view. In one template I have that is using a query view I am using a variable in my Bex query. This variable is of type customer exit, is set to variable is ready for input and calls some ABAP code which returns the current fiscal week number and year. When I run the query or query view in isolation through Bex analyzer the variables gets populated correctly. In my web template I have associated my variable from my query view to a drop down list box. However when I run the Iview created from this template the query results get refreshed but my drop down list box does not, it still shows last weeks week number. How do I get the drop down list box to refresh with the latest result from my customer exit variable?
Regards
Collin

Hi ,
According to your description, my understanding is that you want to filter a calendar based a look up column in SharePoint 2013.
Calendar View not support OOTB filters connection. it is disabled for calendar view, you need to change view(not calendar view) so OOTB filters works and get connected to your view.
You can achieve this using combination of jQuery and SharePoint OOB techniques.
For jQuery filters refer to the blog: enter SharePoint List Filters using jQuery
Also you can filter Calendar View Web Part using JQuery and SPServices:

http://spservices.codeplex.com/discussions/258846
Another way, you can have a look at the SPFilterCalendar :
