The following VF page will not compile with the reRender attribute specified as shown below. The specific error is that cmd is not a property of the standard controller. If I remove the reRender attribute the page compiles successfully. Note that details have been removed for brevity.

<apex:page standardController="MyObj__c" extensions="MyController" > ... <apex:repeat value="{!commands}" var="cmd"> <apex:commandLink action="{!cmd.execute}" value="{!cmd.label}" rendered="{!cmd.enabled}" styleClass="actionLink" title="{!cmd.label}" reRender="{!IF(cmd.isDmlCommand,'myPanel','')}" /> <apex:outputText value=" | " /> </apex:repeat> ... </apex:page> public class MyController {

... public ICommand[] commands {get; set;} } public interface ICommand { String getlabel(); Boolean getenabled(); Boolean getisDmlCommand(); PageReference execute(); }

I have a component that accepts a Boolean attribute. Certain combinations of inline functions generate the error message shown in the subject line. See code below for details:

<!-- this produces the error --> <c:myComponent myBooleanValue="{!LEN(myObj__c.myField__c) == 0}" .../> <!-- this produces the error --> <c:myComponent myBooleanValue="{!LEN(myObj__c.myField__c) = 0}" .../> <!-- this works! --> <c:myComponent myBooleanValue="{!NOT(LEN(myObj__c.myField__c) > 0)}" .../>

Obviously I have a workaround (the last example) but I'm curious to know why the other two do not work.

This doesn't seem to be allowed. I've tried inline functions, controller properties, custom component attributes - in all cases the binding is ignored.

Is there a restriction on using bindings for this attribute?

I can't seem to access this property either through the $ObjectType global variable or through Apex describe calls.

Any suggestions?

Clicking the label in the following VF page does not set the focus to the inputText component. When you examine the generated HTML you observe that the id of the for attribute in the outputLabel is incorrect.

apex:page standardController="MyObj__c"> <apex:form > <apex:pageBlock mode="edit"> <apex:pageBlockButtons > <apex:commandButton value="Save" action="{!save}"/> </apex:pageBlockButtons> <apex:pageMessages ></apex:pageMessages> <apex:pageBlockSection title="Information" showHeader="true"> <apex:pageblockSectionItem > <apex:outputLabel for="typeInput" value="Type"/> <apex:outputPanel id="typePanel"> <apex:actionStatus id="typeStatus"> <apex:facet name="start"> </apex:facet> <apex:facet name="stop"> <c:inputPanel fieldLabel="Type" fieldRequired="true" errorVar="typeError"> <apex:inputText id="typeInput" value="{!MyObj__c.Type__c}" styleClass="{!typeError.errorStyleClass}"/> </c:inputPanel> </apex:facet> </apex:actionStatus> </apex:outputPanel> </apex:pageblockSectionItem> </apex:pageBlockSection> </apex:pageBlock> </apex:form> </apex:page>

If I remove the inputPanel custom component then it works. If I move the inputPanel custom component (and its content) outside of the actionStatus but inside outputPanel (id=typePanel) it also works (which suggests to me that there is not an issue with the custom component).

It almost seems that if the component you want to associate the label with is far enough away the id does not generate correctly.

This behaviour was observed in API 16.

I have a VF edit page where changing one input value affects another (e.g. region and city select lists where selecting the regions filters the selectable list of cities). This was accomplished with actionSupport components as shown:

<!-- region --> <apex:pageBlockSectionItem > <apex:outputLabel for="regionSelectList" value="{!$ObjectType.Gem_Event__c.Fields.Region__c.Label}"/> <apex:outputPanel id="regionPanel" layout="none"> <apex:actionStatus id="regionStatus"> <apex:facet name="start"> <img src="{!$Resource.ActionStatusLoading}"/> </apex:facet> <apex:facet name="stop"> <apex:selectList id="regionSelectList" value="{!region}" size="1"> <apex:selectOptions value="{!regionOptions}"/> <apex:actionSupport event="onchange" rerender="cityPanel,formMessages" status="cityStatus" action="{!clearCity}"/> </apex:selectList> </apex:facet> </apex:actionStatus> </apex:outputPanel> </apex:pageBlockSectionItem> <!-- city --> <apex:pageBlockSectionItem > <apex:outputLabel for="citySelectList" value="{!$ObjectType.Gem_Event__c.Fields.Gem_City__c.Label}"/> <apex:outputPanel id="cityPanel" layout="none"> <apex:actionStatus id="cityStatus"> <apex:facet name="start"> <img src="{!$Resource.ActionStatusLoading}"/> </apex:facet> <apex:facet name="stop"> <apex:selectList id="citySelectList" value="{!Gem_Event__c.Gem_City__c}" size="1"> <apex:selectOptions value="{!cityOptions}"/> <apex:actionSupport rendered="{!ISNULL(region)}" event="onchange" rerender="cityPanel,regionPanel,formMessages" status="regionStatus"/> </apex:selectList> </apex:facet> </apex:actionStatus> </apex:outputPanel> </apex:pageBlockSectionItem>

Then I had need to rerender the entire section when another input field was changed, so I wrapped the entire page block section inside an actionStatus component. Only when I did all this all the start facets of the inner actionStatus components stopped working (the re-rendering continued to work however).

Eventually I had to abandon wrapping the entire section within an actionStatus component.

Is there a restriction on having nested actionStatus components? 

<apex:form> <apex:actionStatus id="loadingFormDefaultsStatus"> <apex:facet name="start"> <apex:image url="{!$Resource.ActionStatusLoading}"/> <apex:outputText value=" loading defaults..."/> </apex:facet> <apex:facet name="stop"/> </apex:actionStatus> ... </apex:form>

In the above VF page snippet only the outputText component of the start facet gets rendered. If I switch the order then only the image component gets rendered.

I eventually got around this by using standard HTML tags but I was wondering if there was some limitation as to what one could include in an actionStatus facet.

This behaviour was observed in API 16.

If you create a pageBlockSection the mouseover help for the show/hide icon should include the section title, as in:

Show Section - My Section, or

Hide Section - My Section

However, after the first mouse click the section title text vanishes and you're left with:

Show Section - , or

Hide Section -

I believe the root cause of this is that the <img ...> tag in the resulting HTML does not include a name attribute which has the value of the title text (e.g. <img name="My Section" ... />)

If you contrast the VF HTML to that of a section on a standard page you'll note this difference.

I was wondering if somebody could help me. I have create a dynamic picklist controller that collects it select list from a custom lookup table

I have a custom field called Municapaly on the Account object and I would like to link and update this field from this new controller 

}

I have a javascript function (using Protovis) that draws a dynamic pie chart in my Visualforce page. The pie chart is contained within an outputPanel, and a button at the top of the page rerenders that outputPanel. The javascript works perfectly the first time the page is loaded. However, after the button is pressed and the section rerenders, the javascript never executes a second time -- the pie chart disappears and the alert on line 16 does not fire. How can I make sure my function executes after the rerender event?

<apex:page controller="devTracking" > <script type="text/javascript" src="{!URLFOR($Resource.Protovis, 'protovis-r3.1.js')}"></script> <apex:form > <apex:commandButton id="goButton" value="Go" action="{!start}" rerender="container"></apex:commandButton> </apex:form> <apex:outputPanel id="container"> <apex:pageBlock title="Sample Protovis Graph"> <script type="text/javascript+protovis"> function renderMe() { alert('debug #1'); var data = pv.range(10).map(Math.random).sort(pv.reverseOrder), w = 400, h = 400, r = w / 2, a = pv.Scale.linear(0, pv.sum(data)).range(0, 2 * Math.PI); var vis = new pv.Panel() .width(w) .height(h); vis.add(pv.Wedge) .data(data) .bottom(w / 2) .left(w / 2) .outerRadius(r) .angle(a) .title(function(d) d) .add(pv.Wedge) // invisible wedge to offset label .visible(function(d) d > .15) .innerRadius(2 * r / 3) .outerRadius(r) .fillStyle(null) .anchor("center").add(pv.Label) .textAngle(0) .text(function(d) d.toFixed(2)); vis.render(); } renderMe(); </script> </apex:pageBlock> </apex:outputPanel> </apex:page>

Is there a way to get description information for a custom object field in Visualforce? I have a need to iterate over fields of a custom object and create a layout in 3 columns, column 1 - Label , column 2 - Input field, column 3- description information for that input field.

Is this possible in Visualforce? I am trying to replicate a 3 column word document in Salesforce.com.

Hi all,

I'm attempting to add to the default page layout of a case object with a Visual Force page.

My supposrt staff have mentioned that case comments require too many clicks and page loads to get done, and would like a simple input field on the case page with a save button under it. Entering text, and then clicking save adds the comment to the case and clears the box for the next comment.

I've attempted to create this but without success. I can't figure out how to put an input field for a new child object on a visual force page.

My page looks like this:

<apex:page standardController="Case" extensions="caseLogisticsPageCtrlr" tabStyle="Case" > <apex:pageBlock> <apex:form > <apex:pageBlockTable rows="5" value="{!case.CaseComments}" var="cCom"> <apex:column> <apex:inputField value="{!cCom.CommentBody}"/> </apex:column> </apex:pageBlockTable> </apex:form> </apex:pageBlock> </apex:page>

 But as I'm sure you can tell... It just shows input fields from existing comments. 

My controller is this:

public class caseLogisticsPageCtrlr{ private final Case cse; public caseLogisticsPageCtrlr(ApexPages.StandardController stdController) { this.cse = (Case)stdController.getRecord(); } public Case getCase() { return [select id, CaseNumber, (select id, CommentBody, ParentId from CaseComments limit 5) from Case where id = :System.currentPageReference() .getParameters().get('id')]; } public String getName() { return 'caseLogisticsPageCtrlr'; } }

 I think I'm on the wrong track... Can anyone please help me out?

Thanks,

Jnic
