Get link to process of another project

ahatius — Thu, 27 Nov 2014 08:25:46 -0500

ivy.html.startref allows me to get a link to another process starts. Unfortunately this only seems to work within the same project.

Is there any way I can get a link to the process start of another project? Using ivy.html.startref("Projectname/Processname/startName.ivp") or ivy.html.startref("../Projectname/Processname/startName.ivp") don't seem to work.

Access IHttpRequest object

ahatius — Wed, 26 Nov 2014 14:23:22 -0500

Is there any way I can gain access to the object that implements IHttpRequest so that I can eventually get the HttpServletRequest object?

I'd like to be able to read HTTP-Headers from within the application (I'm not talking about GET or POST parameters, I want the HTTP Headers). The ivy.request object only enables me access to the GET parameters.

Labels in process title

ahatius — Mon, 24 Nov 2014 18:10:49 -0500

Is there any way I can use labels from the cms as process title? When I insert a label, it'll just show the plain code, instead of getting the actual value.

We have users that speak German, French and Italian - I had this issue already on Ivy 4.3 but I was hoping that there would have been a solution for this issue with 5.1. Do I have to do something special in order to get it working?

Mail simulation on server

ahatius — Mon, 24 Nov 2014 15:06:52 -0500

The Designer provides the function to test the mail step - it always sends the mail to the developer but shows to who it should have been sent.

Is there any way I can get this behaviour on the server? After testing everything on the designer, I'd like to test everything on the server - unfortunately this would send each mail to the real person which would be a bit annoying.

selectOneMenu: Value will not be set

ahatius — Thu, 13 Mar 2014 10:29:21 -0400

I've got a dropdown menu, which gets the persons from our LDAP server. What I basically did was copying the SelectOneMenuDemo from the Demo files.

However, it's displaying all persons correctly in the dropdown, but it won't set the selected person to my data.manager.

This is the code from the demo:

<p:selectonemenu value="#{data.selectedPerson}" converter="ivy.ListItem">
<f:selectitem itemlabel="Select One" itemvalue=""/>
<f:selectitems value="#{data.persons}" var="it" itemvalue="#{it}" itemlabel="#{it.name}"></f:selectitems> <f:selectitems value="#{data.morePersons}" var="it" itemvalue="#{it}" itemlabel="#{it.name}"></f:selectitems> <f:selectitem itemvalue="#{data.onePerson}" itemlabel="#{data.onePerson.name}"></f:selectitem> </p:selectonemenu>

And this is what I wrote:

<p:selectonemenu id="manager" value="{data.manager}" converter="ivy.ListItem" style="width: 200px;"> <f:selectitems value="#{data.managers}" var="it" itemvalue="#{it}" itemlabel="#{it.cn}"></f:selectitems> </p:selectonemenu>

Is there something I've forgotten? This looks exactly the same to me. Do I have to do something when I submit? I've got a multiview HTML dialog.

How to authenticate a user that is provided by a Single Sign On (SSO) proxy.

ahatius — Sat, 25 Jan 2014 15:28:14 -0500

We've got a SSO-Proxy for most of our web applications. I'd like to make use of the SSO-Proxy instead of requiring the user to login with his Windows credentials.

I've figured out how I can read the HTTP header containing the user-id. Now I'd like to authenticate as this user, but all provided methods require a password. Is there anyway I can authenticate a user only by his user-id?

This is what I've got to get the user-id:

package ch.company.ivy.security;

import java.util.Map;

import javax.faces.context.FacesContext;

public class Auth {
    Map<String, String> headers;
    String userId;

    public Auth() {
        headers = FacesContext.getCurrentInstance().getExternalContext().getRequestHeaderMap();
        userId = headers.get("UID").toString();
    }

    public String getUserId() {
        return this.userId;
    }
}

Dynamic amount of fileuploads: file not uploading

ahatius — Tue, 21 Jan 2014 20:34:00 -0500

I'd like to give the user the ability to choose the amount of attachments he'd like to provide. To do this I created a datatable with buttons to add and remove attachment-lines:

<p:dataTable id="attachments" var="attachment" value="#{data.attachments}">
    <p:column headerText="#{ivy.cms.co('/labels/vendor')}"><p:inputText value="#{attachment.vendor}" /></p:column>
    <p:column headerText="#{ivy.cms.co('/labels/description')}"><p:inputText value="#{attachment.description}" /></p:column>
    <p:column headerText="#{ivy.cms.co('/labels/amount')}"><p:inputText value="#{attachment.amount}" /></p:column>
    <p:column headerText="#{ivy.cms.co('/labels/attachment')}"><p:fileUpload value="#{attachment.file}" mode="simple" /></p:column>
    <p:column headerText=""><p:commandButton value="delete-row" update="attachments" action="#{logic.deleteAttachment(attachment)}" /><p:commandButton value="add-row"  update="attachments" action="#{logic.addAttachment()}" /> </p:column>
</p:dataTable>

The only problem is, that it seems to not upload the specified file. The submitted form is beeing processed by this script, the output of in.test beeing false:

for(Integer i = 0; i < in.attachments.size(); i++) {
    in.test = in.attachments.get(i).file.exists().toString();
}

The Simple-Fileupload-Demo works, so I guess it can't be a problem with my installation / computer. I just cleared all of the attachments and uploaded only one. So while this is a foor loop, it just iterates through 1 time. Data is stored in my own Data Class Attachment, containing 4 attributes (Vendor, Description, Amount and File).

Autocomplete ignores itemValue attribute

ahatius — Sun, 19 Jan 2014 18:43:57 -0500

I'd like to build an input field with the autocomplete widget, so the user can search for one of our dealer locations.

To do this, I've created a class Dealer and a class AutocompleteSource which should provide the data structure and the data itself. They look like this:

AutocompleteSource.java

package ch.company.ivy.investitionsantrag;

import java.util.ArrayList;
import java.util.List;

import ch.company.ivy.investitionsantrag.Dealer;
import ch.ivyteam.ivy.environment.Ivy;

import com.unboundid.ldap.sdk.LDAPConnection;
import com.unboundid.ldap.sdk.LDAPException;
import com.unboundid.ldap.sdk.LDAPSearchException;
import com.unboundid.ldap.sdk.SearchResult;
import com.unboundid.ldap.sdk.SearchResultEntry;
import com.unboundid.ldap.sdk.SearchScope;

public class AutocompleteSource {
    public LDAPConnection ldapServer;

    public AutocompleteSource() throws LDAPException {
        this.ldapServer = new LDAPConnection(Ivy.var().get("LDAPHost"), Integer.parseInt(Ivy.var().get("LDAPPort")));
        ldapServer.bind(Ivy.var().get("LDAPUser"), Ivy.var().get("LDAPPassword"));
    }

    public List<Dealer> searchDealers(String query) throws LDAPSearchException {
        List<Dealer> dealers = new ArrayList<Dealer>();
        SearchResult searchResult = this.ldapServer.search("dc=COMPANY,dc=CH", SearchScope.SUB, "(&(|(imDealerNetwork=CHE001)(imDealerNetwork=CHE017)(imDealerNetwork=CHE003)(imDealerNetwork=CHE010))(|(cn=*" + query + "*)(imCity=*" + query + "*)))");

        for (SearchResultEntry entry : searchResult.getSearchEntries()) {
             dealers.add(new Dealer(entry.getAttributeValue("cn"), entry.getAttributeValue("imCity")));
         }

        return dealers;
    }
}

Dealer.java

package ch.company.ivy.investitionsantrag;

public class Dealer {
    public String id;
    public String city;
    public String label;

    public Dealer(String id, String city) {
        id = id.replaceFirst("^0+(?!$)", "");
        this.id = id;
        this.city = city;
        this.label = id + " " + city;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }

    public String getLabel() {
        return label;
    }

    public void setLabel(String label) {
        this.label = label;
    }

}

I've created a method dealers which takes the query string and executes the following code:

import ch.company.ivy.investitionsantrag.*;
AutocompleteSource source = new AutocompleteSource();
in.dealers = source.searchDealers(in.query);

And finally, my call of the autocomplete in the view:

<p:autoComplete id="dealer" completeMethod="#{logic.dealers}" required="false" var="dealer" itemLabel="#{dealer.label}" itemValue="#{dealer.id}" forceSelection="true" value="#{data.dealer}" />

The autocomplete works, it takes the query and gets the results from the LDAP server. But when I select one of the suggestions it puts the whole label into the input field instead of only the id. Am I doing something wrong?

Update: I just noticed that it in fact does use the value specified in itemValue - it's just in the background. Anyway to tell primefaces to make the visible value in the input field the same as in the background?

PrimeFaces: Autocomplete using user dialog method

ahatius — Sat, 09 Nov 2013 21:53:19 -0500

Hi there

I've created some workflows in Ivy 4.x, using the Web Page component in the designer. Most of the functionality was coded with jQuery.

Now I'd like to switch to Ivy 5. On my old workflow I used jQuery-UI autocomplete to get a list of organization units from our LDAP server. According to the PrimeFaces documentation there is a autocomplete tag. While there are examples on how to use the functions with a regular Java-environement, I couldn't figure out how to use it in Xpert.Ivy.

What I've got is an user-dialog, consisting of one start method and another method, which should retrieve the results from the LDAP server, based on the query-text in the input field.

I'd be happy if someone could explain to me, how I'd have to setup the autocomplete tag and what format my method has to return, in order for the autocomplete to work.

Thank you :) Ahatius
