[SalesForce] apex param in apex repeat (pass parameter to controller in repeat) not working

I have an apex:repeat and I want to use and apex:param in it. The repeater shows the userName of the person who liked the feed (like.user.Name). And if this userName is same as the person who has logged in (activeUser.Name) then, I'm showing the outputText as You.

Basically, the rendered condition in outputText shown below is not working. The rendered condition calls a method and checks the param that I passed above is equal to the activeUser.Name and then returns true/false.

I checked the debug logs and found that "LikedUserName" param is getting null. how do I set the param value from the apex:repeat.

<apex:repeat value="{!feedItem.likes.likes}" var="like">
    [{!like.user.Name}] 
    <apex:param name="LikedUserName" value="{!like.user.Name}" assignTo="{!LikedUserName}" />
    <apex:outputText value="You!" rendered="{!LikedByYou}" />                                       
</apex:repeat>

>

public String LikedUserName{get;set{LikedUserName=value;}}

public boolean getLikedByYou(){
    if(activeUser.Name == ApexPages.currentPage().getParameters().get('LikedUserName')){
        return true; 
    }
    else return false;
}

Best Answer

Instead you can use the IF condition in the value attribute of the outputText

<apex:outputText value="{!IF(activeUser.Name == like.user.Name, 'You', like.user.Name)}" />

[SalesForce] ActionFunction working in Chrome but not in IE and Moz

Try to use jQuery to trigger on the keyPress/keyDown events. Additionally i leave the value parameter empty if i want to set it from another javascript function and use reRender to refresh some areas:

<script>
jQuery('[id$=myField]').on('keydown keypress keyup', function(event) {
    if (event.keyCode == 13) {
        event.preventDefault();
        insertOffer(jQuery(this).val());
    }
});
</script>


<apex:actionFunction name="insertOffer" action="{!setNewBidOffer}" reRender="myField">
     <apex:param name="currOffer" value="" assignTo="{!currentOffer}"/>
</apex:actionFunction>

<apex:inputText value="{!currentOffer}" id="myField"/>

But one thing i don't understand: you trying to set the currentOffer variable to the currentOffer variable?

[SalesForce] conditional rendering of apex :repeat element

A wrapper class is useful in this scenario. There is not enough controller code in the question to know for sure, but the implementation may look like something like this:

In the controller, define the wrapper class and change the method to return wrappers rather than sObjects. The controller will build the wrapper and set the isRendered member variable based on whether the sObject is contained in a Set someplace else in the controller.

public class ProposalWrapper {
    public Proposal__c proposal     { get; set; }
    public Boolean     isRendered   { get; set; }
}

public List<ProposalWrapper> getProposalWrappers() {
    List<ProposalWrapper> proposalWrappersToReturn = new List<ProposalWrapper>();

        // iterate over the list of Proposal__c sObjects
    for (Proposal__c proposal : ProposalsFromSomeList) {

        // create a wrapper to allow you to indicate visibility
        ProposalWrapper pWrapper = new ProposalWrapper();

        // stick the sObject into the wrapper
        pWrapper.proposal = proposal;

        // set the boolean field true/false based on whether the item is in the set
        pWrapper.isRendered = yourSet.contains(proposal);

        // add the wrapper to the list being returned
        proposalWrappersToReturn.add(pWrapper);
    }

    return proposalWrappersToReturn;

}

In the page:

<!-- iterate over the wrappers and use the boolean field to control visibility -->
<apex:repeat value="{!ProposalWrappers}" var="item">
    <apex:outputPanel rendered="{!item.isRendered}">
        <li>
            <apex:outputText value="{!item.proposal.Id}" />
            <apex:outputText value="{!item.proposal.Name}" />
    </apex:outputPanel>
</apex:repeat>
