I'm trying to add a button to the contact form which creates a child activity record linked to the parent contact.I'm using the Ribbon Workbench to attempt this.I've got the button showing successfully but I can't get the child record to be created.The Ribbon Workbench won't publish the below xmlThe XML I have so far is:\[code\] <?xml version="1.0" encoding="utf-16"?><RibbonDiffXml xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <CustomActions> <CustomAction Id="new.contact.Button1.Button.CustomAction" Location="Mscrm.Form.contact.MainTab.Actions.Controls._children" Sequence="19"> <CommandUIDefinition> <Button Command="new.contact.Command0.Command" Description="Send SMS" Id="new.contact.Button1.Button" Image32by32="$webresource:new_sms32" Image16by16="$webresource:new_sms16" LabelText="$LocLabels:new.contact.Button1.Button.LabelText" Sequence="19" TemplateAlias="o1" ToolTipTitle="$LocLabels:new.contact.Button1.Button.ToolTipTitle" ToolTipDescription="$LocLabels:new.contact.Button1.Button.ToolTipDescription" /> </CommandUIDefinition> </CustomAction> </CustomActions> <Templates> <RibbonTemplates Id="Mscrm.Templates" /> </Templates> <CommandDefinitions> <CommandDefinition Id="new.contact.Command0.Command"> <EnableRules /> <DisplayRules /> <Actions> <JavaScriptFunction FunctionName="AddSMS" Library="$webresource:new_WFTrigger"> <StringParameter Name="child" Value="http://stackoverflow.com/questions/11365473/new_sms" /> <CrmParameter Name="parentRecordId" Value="http://stackoverflow.com/questions/11365473/PrimaryItemIds" /> <CrmParameter Name="parente" Value="http://stackoverflow.com/questions/11365473/PrimaryEntityTypeCode" /> <!--The ribbon workbench refuses to fill the Name of this parameter and tries to publish it as blank --> </JavaScriptFunction> </Actions> </CommandDefinition> </CommandDefinitions> <RuleDefinitions> <TabDisplayRules /> <DisplayRules /> <EnableRules /> </RuleDefinitions> <LocLabels> <LocLabel Id="new.contact.Button1.Button.LabelText"> <Titles> <Title description="Send SMS" languagecode="1033" /> </Titles> </LocLabel> <LocLabel Id="new.contact.Button1.Button.ToolTipTitle"> <Titles> <Title description="Send SMS" languagecode="1033" /> </Titles> </LocLabel> <LocLabel Id="new.contact.Button1.Button.ToolTipDescription"> <Titles> <Title description="Send SMS" languagecode="1033" /> </Titles> </LocLabel> </LocLabels></RibbonDiffXml>\[/code\]And the javascript web resource I have is:\[code\]function AddSMS(child, parente, parentRecordId) { var url = Xrm.Page.context.getServerUrl() + "main.aspx?etn= " + child + " &extraqs=%3f_CreateFromId%3d" + parentRecordId + "%26_CreateFromType%3d" + parente + "%26etn%" + child + " &pagetype=entityrecord";open(url, 'Create SMS');}\[/code\]Update: a problem developed in my environment so I've started a new organisation to develop the cusomtisations. When I get back to the same point I'll come back to this thread. Thanks!
