setting up hashmap key in t:SelectBooleanCheckbox in a dataTable

[vishnu bola]

Hi all,

iam new to JSF and have a problem with my t:SelectBooleanCheckbox tag.

In my dataTable there is a column
<t:column>
<t:selectBooleanCheckbox id="checkbox4" value="#{manageuserscontroller.selectedUserIds[user.id-cols.accountID]}" />
</t:column>

the key is a string with a combination of userID and accountID with hyphen(-) in the middle. eg:"123-456" Iam not sure how to dynamically populate the key in my dataTable column. Please advise.

I already posted this query in sun forums http://forums.sun.com/thread.jspa?threadID=5415508 but didn't get a response.So iam reposting the query here. Please advise.

Hi mallika,

Iam happy to see some response. Ok let me copy my entire code below. I have dataTable :
<h:form id="groupuserlist">
<t:dataTable id="groupuserlist"
var="user"
value="#{manageuserscontroller.userList}"
binding="#{manageuserscontroller.userTable}"
styleClass=" marVertSml"
cellspacing="0"
preserveDataModel="false"
headerClass="topRow"
summary="This table displays list of users for an accessgroup">
<t:column>

<f:facet name="header"><hutputText value="User ID" /></f:facet>

<tutputText value="#{user.ID}" />
</t:column>
<t:column>

<f:facet name="header"><t:commandLink value="Title" /></f:facet>

<tutputText value="#{user.title}" />

</t:column>
<t:columns var="cols" value="#{manageuserscontroller.selectedAGList}">
<f:facet name="header"><hutputText value="#{cols.name}" /></f:facet>



<t:selectBooleanCheckbox id="checkbox4" value="#{manageuserscontroller.selectedUserIds[user.ID-cols.accountID]}" />

</t:columns>

In my backing bean ManageUsersController I have hashmap
private Map<String, Boolean> selectedUserIds = new HashMap<String, Boolean>();

This hashmap get populated from the database and the data in it is something like
("123-456",true) where 123 is the userID and 456-accountID.

Now this key acts as checkbox value in my dataTable. Now my problem is iam not able to construct the key inside EL in this format. Kindly need help.

Hi,

you have selected items in backing bean so concatenate two of them pass it as a string.

If you still not understand this logic..please paste your backing bean code so i can suggest.

Hi Mallika i am not really clear on what you mean by concatenation. Here is my backing bean code.

 private Map<String, Boolean> selectedUserIds = new HashMap<String, Boolean>();
   	for(int i=0; i < userList.size();i++){
	   for(int j=0; j< selectedAGList.size(); j++){
	try {

	 selectedUserIds = AccountDAO.getUserMap(userList.get(i).getID(),selectedAGList.get(j).getAccessGroupID());
					
                 }
My Account DAO:
 ResultSet rs = executeSQL(sql,list);
	    
	    while(rs!=null & rs.next()){
	    	int uid = rs.getInt("iuserd");
	    	int aid = rs.getInt("iaccountid");

	    	String key = String.valueOf(uid) + "-" + String.valueOf(aid); 
	
	    	selectedIds.put(key,true);
}

I am deliberately setting up keys for all the selected checkboxes in that format ("123-456")because i want to extract the userid later for some other processing. I didn't find any other way to to it. Please advise.

Hi,

I am not able to understand by looking at the below code.

I will look in to it if you can please post entire code otherwise it is difficult for me to understand piece of codes which are syntactically not correct...

Why dont you guys use Code tags ??

Please do so, its makes your post easier to read, It is possible to edit post and add code tags too.
