Understand below code, may help. make neccessary changes as required. Below code allows maximum (4) number of attachments.
--Check attachments
public void checkAttachment(com.sun.java.util.collections.HashMap hsMap)
OAPageContext oapagecontext = (OAPageContext)hsMap.get("PageContextObject");
OAWebBean oawebbean = (OAWebBean)hsMap.get("WebBeanObject");
OAApplicationModule am = oapagecontext.getApplicationModule(oawebbean);
String amName = "";
String objectivesAMName = "OAAttachmentsAM"; //-- Standard attachment AM
String objectiveVOName = "FndAttachedDocumentsDomExtensionVO"; //-- Attachment VO
String nestedAMArray[] = am.getApplicationModuleNames();
OAApplicationModule currentAM = null;
OAViewObject vo = null;
currentAM = am;
for(int i = 0; i < nestedAMArray.length; i++)
amName = nestedAMArray.toString();
oapagecontext.writeDiagnostics(this,"Nested AM Name=>"+amName + "and amName.indexOf(objectivesAMName) "+amName.indexOf(objectivesAMName),1);
currentAM = (OAApplicationModule)am.findApplicationModule(amName);
if(!(amName.indexOf(objectivesAMName)==-1))
String[] viewNames = currentAM.getViewObjectNames();
for (int j =0 ;j<viewNames.length ;j++ )
if(viewNames[j].indexOf(objectiveVOName) > 0)
vo = (OAViewObject)currentAM.findViewObject(viewNames[j]);
int attchcount = vo.getFetchedRowCount();
if(attchcount>4)
throw new OAException("XXC","XXC_MAX_ATTACHMENTS");
//return isAttachmentFound;
