I'm using a custom controller, wrapper, and a visualforce page trying to pass a List of selected items into a Visual Workflow.
I'm able to run the query and make a selection, via the wrapper, in the VF page, and I know that the variable I'm trying to pass is populating values (as I've checked the debug logs) but I am unable to get it to pass into the visual workflow. Can someone help?
Below is my controller:
public class RibbonClauseSearchControllerv2 {
// the results from the search. do not init the results or a blank rows show up initially on page load
public List<RibbonClauseWrapper> searchResults {get;set;}
List<RibbonClause__c> ribbonClauseList;
public List<RibbonClause__c> getRibbonClauseList() {
return ribbonClauseList;
}
// the categories that were checked/selected.
public List<RibbonClauseWrapper> selectedRibbonClauses {
get {
if (selectedRibbonClauses == null) selectedRibbonClauses = new List<RibbonClauseWrapper>();
return selectedRibbonClauses;
}
set;
}
// the text in the search box
public string searchText {
get {
if (searchText == null) searchText = 'Type Value'; // prefill the search box for ease of use
return searchText;
}
set;
}
// constructor
public RibbonClauseSearchControllerv2() {}
// fired when the search button is clicked
public PageReference search() {
if (searchResults == null) {
searchResults = new List<RibbonClauseWrapper>(); // init the list if it is null
} else {
searchResults.clear(); // clear out the current results if they exist
}
// Note: you could have achieved the same results as above by just using:
// searchResults = new List<RibbonClauseWrapper>();
// dynamic soql for fun
String qry = 'Select rc.Name, rc.Id, rc.Text__c, rc.Clause_Name__c, rc.Additional_NST_Details__c From RibbonClause__c rc Where rc.Name LIKE \'%'+searchtext+'%\' Order By rc.Name';
// may need to modify for governor limits??
for(RibbonClause__c rc : Database.query(qry)) {
// create a new wrapper by passing it the category in the constructor
RibbonClauseWrapper rcw = new RibbonClauseWrapper(rc);
// add the wrapper to the results
searchResults.add(rcw);
}
return null;
}
public PageReference next() {
List<RibbonClause__c> ribbonclauseList = new List<RibbonClause__c>();
// clear out the currently selected
// selectedRibbonClauses.clear();
// ribbonclauseList.clear();
// add the selected ribbonclause to a new List
for (RibbonClauseWrapper rcw : searchResults) {
if (rcw.checked)
ribbonclauseList.add(rcw.rc);
}
// // Now we have our list of selected contacts and can perform any type of logic we want, sending emails, updating a field on the Contact, etc
// System.debug('These are the selected Ribbonclauses...' + ribbonclauseList);
// for(RibbonClause__c rcf: ribbonclauseList) {
// system.debug(rcf);
// }
// ribbonclauseList =null; // we need this line if we performed a write operation because getContacts gets a fresh list now
return Page.RibbonClause_Results;
// return null;
}
// fired when the back button is clicked
public PageReference back() {
return Page.RibbonClause_Search;
}
// fired when no clause available button is clicked
public PageReference noclause() {
return Page.clauseKeyPage;
}
public PageReference getListView() {
return new PageReference('https://cs-iris--rksb1.cs17.my.salesforce.com/a1X?fcf=00Bg0000001HSu1');
}
public class ribbonClauseWrapper {
public Boolean checked{get;set;}
public RibbonClause__c rc{get;set;}
public RibbonClauseWrapper(){
rc = new RibbonClause__c();
checked = false;
}
public RibbonClauseWrapper(RibbonClause__c rc2){
rc = rc2;
checked = false;
}
}
}
This is my Visualforce Page that initiates the Flow.
<apex:page controller="RibbonClauseSearchControllerv2">
<apex:form >
<apex:pageBlock rendered="True" >
<apex:pageBlockButtons >
<apex:commandButton action="{!back}" value="Back"/>
</apex:pageBlockButtons>
<apex:pageMessages />
<apex:pageBlockSection title="You Selected" columns="1" collapsible="true">
<apex:pageBlockTable value="{!selectedRibbonClauses}" var="rc2" style="width:100%">
<apex:column value="{!rc2.rc.Name}" headerValue="Name" Style="width:100px"/>
<apex:column value="{!rc2.rc.Text__c}" headerValue="Language" Style="width:600px"/>
<apex:column value="{!rc2.rc.Id}" headerValue="Id" Style="width:1px" rendered="false" />
</apex:pageBlockTable>
</apex:pageBlockSection>
</apex:pageBlock>
</apex:form>
<flow:interview name="Approval_Record_Creation" buttonLocation="top" finishLocation="{!ListView}">
<apex:param name="cv_RibbonClauseId" value="{!ribbonClauseList}" />
<apex:param name="v_UserId" value="{!$User.Id}"/>
<apex:param name="vMId" value="{!$CurrentPage.parameters.Id}"/>
</flow:interview>
</apex:page>
The parameter giving me trouble is
apex:param name="cv_RibbonClauseId" value="{!ribbonClauseList}"
When I hard code an ID for the value here then it passes into my flow fine.
I also ran a System.Debug in the controller for the ribbonClauseList in the controller. I commented it out in the controller that I've pasted here, but the snippet of it is below:
System.debug('These are the selected Ribbonclauses...' + ribbonclauseList);
for(RibbonClause__c rcf: ribbonclauseList) {
system.debug(rcf);
In the Debug logs it shows records of type RibbonClause__c, so i know that the variable is being populated.....
So.. 1) I can hardcode a value in the VF page for the flow variable which comes through correctly in the floe and 2) I know that the variable I'm trying to pass into the flow is being populated with values... Can someone help me understand where the gap is that I'm missing?
