Notes: Ein- und Ausblenden von View-Actions

Heute mal ein kleiner Tipp für Standard-Notesclient Anwendungen.

Ich hatte die Anforderung bekommen dass in einer kategorisierten View die Actions ein- und ausgeblendet werden sollen, je nachdem ob ich eine Kategorie oder ein Dokument ausgewählt habe. Langes Suchen brachte nichts und auch ein Kollege war der Meinung es geht nicht. Ein anderer Kollege brachte dann aber doch die Lösung:

In den View-Einstellungen gibt es eine Option namens “Evaluate actions for every document change”. Das funktioniert deshalb weil auch ein Wechsel der Selektion als Change aufgefasst wird.
Schlussendlich muss man in der Hide-When Formel nur noch auf die Form abfragen. Wenn sie leer ist verstecke den Button, wenn nicht dann zeige ihn an, denn Kategorien haben keine Form.

Darüber hinaus kann man so natürlich noch sehr flexibel entsprechende Actions anzeigen, beispielsweise wenn man in der View mehrere Forms hat.


XPages: Collection of advices

Hi folks,

here is a small collection of some hints which were written by my colleagues and myself throughout time.

Naming of attributes in Internet Explorer

It seems, in the Internet Explorer, Dojo has some problems finding the correct element, while usingattribute selectors, if there is a string reserved by the system in the attribute. (e.g. name or id). Because Dojo uses the selector engine “Sizzle” like JQuery, the same phenomenon can appear using JQuery.

An example for that is an input-field with the name “username”. If you select dojo.query(‘input[id$=”WFApprovalVFL”]’) the field “username” will be selected, too, although it doesn’t end with WFApprovalVFL.

The same happens with keynames in JSON-objects.

Not rendered datasources will always be computed

If you use a datasource in a custom control, the code of the datasource will always be computed, no matter whether you set rendered or loaded to false. The code will always be computed. This could lead to errors hard to track down.

Furthermore, if you use several datasources in different custom controls, which point to the same document, all these datasources will be saved and, eventually, the document is saved more than once with saveing conflicts. To avoid this, you can reference the datasource in your custom controls directyl via the name, or you can pass on the datasource via a parameter of the custom control (compositeData). Therefore you have to select the class of the datasource, which doesn’t appear in the list of available types. The name of the class of a datasource is

Check whether a viewPanel is categorized

If we have a view control in our XPage which name is viewPanel1 the following code:

var = getComponent("viewPanel1").getDataModel();
return model.getCategoryIndentLevel();

returns the value 0 if view is categorized, it returns -1 if not.

Use case: If you sort a view, the content of a categorized column gets lost. With that you can check whether the view was sorted and reset the view.

Avoid the onChange bug in Internet Explorer when clicking on a CheckBoxGroup

If you use RadioButtonGroups or CheckBoxGroups in an XPage or a custom control, you could face the problem in the Internet Explorer, that after a partial refresh the submitted values of the group are the values from a previous request. This occurs if you click the label of instead of the box, directly. The reason is that the IE submits the partial refresh before setting the new value from the UI.



There is a CheckboxGroup with the options A, B, C and D. In the onChange event, a partial refresh will be fired on another panel, which hides or shows some elements in dependence of the chosen value. If you click the label for Option A, there is no submitted value. If you click the label of option B, the value A is submitted. If you click after that on the label of option C, Ab and B will be submitted.


You can fire the partial refresh a second time in the onComplete event of the onClick event.


The workaround above doesn’t work if there are additional actions or server-side code. The code will be executed only on the first refresh. To get this event-handler working again, you have to hang out the click-event from the standard-action and execute it by yourself. You can achieve that with a scriptblock (The name of the control is Output-Script, you can find it if you open the list of other controls in the sidebar of the Domino Designer) Because the checkbox itself is inside the label, you have to seperate it from the own execution.

 <xp:scriptBlock id="scriptBlock1"
            if ( != "checkbox") {

Another advantage of this method, compared to workaround 1, is that you don’t need a second request.

Validation of two dependen input-fields

While validating two fields dependent of each other, you have to read the value of the field which is validated. If you compare the value of the second field, validation will not be fired after the first fail and the validation error persists.


 <xp:inputText id="recipientNotesID"
   disableClientSideValidation="true" required="true">
      <xp:validateRequired message="Required value."></xp:validateRequired>
<xp:inputText id="recipientNotesPW"
   disableClientSideValidation="true" required="true">
         <xp:this.message><![CDATA[#{javascript:"Values must not be equal."}]]></xp:this.message>
      <xp:validateRequired message="Required value."></xp:validateRequired>
