The @ClientType<\/em> formula provides an interesting behaviour: If you add the value to a label, the result will be as expected. It returns \u201cWeb<\/em>\u201d in Browser and returns \u201cNotes<\/em>\u201d in XPiNC.<\/p>\n

<?xml version=\"1.0\" encoding=\"UTF-8\"?>\r\n<xp:view xmlns:xp=\"http:\/\/www.ibm.com\/xsp\/core\">\r\n   <xp:label value=\"#{javascript:@ClientType()}\" id=\"label1\" \/>\r\n<\/xp:view><\/pre>\n
But if you add it to a computed field on a form and use this form in a datasource, the result in XPiNC is not „Notes<\/em>„, it is „None<\/em>“ instead. In the following example, the form „Test<\/em>“ has a computed field named „ClientType<\/em>„. The value of the field is @ClientType<\/em>.<\/p>\n
<?xml version=\"1.0\" encoding=\"UTF-8\"?>\r\n<xp:view xmlns:xp=\"http:\/\/www.ibm.com\/xsp\/core\">\r\n\r\n   <xp:this.data>\r\n\u00a0\u00a0    <xp:dominoDocument var=\"document1\" formName=\"Test\" \r\n         computeWithForm=\"onload\">\r\n\u00a0\u00a0 \u00a0  <\/xp:dominoDocument>\r\n   <\/xp:this.data>\r\n\r\n\u00a0\u00a0 <xp:label value=\"#{javascript:@ClientType()}\" id=\"label1\" \/>\r\n\u00a0\u00a0 <xp:br \/>\r\n\u00a0\u00a0 <xp:label id=\"label2\">\r\n\u00a0\u00a0    <xp:this.value>\r\n\u00a0\u00a0 \u00a0\u00a0    <![CDATA[#{javascript:\r\n            document1.getItemValueString(\"ClientType\")\r\n         }]]>\r\n\u00a0\u00a0 \u00a0 <\/xp:this.value>\r\n   <\/xp:label>\r\n<\/xp:view><\/pre>\n
[The computeWithForm<\/em> property of the datasource has to be set to „onload<\/em>“ or „onsave<\/em>„. If set to „onboth<\/em>“ this will not work.]<\/p>\n
This behaviour gives you control about the subforms which are used in the form, depending of the client and\/or technology. Just add a computed subform to your form and add a @Formula like this:<\/p>\n
@If(\r\n\u00a0\u00a0 \u00a0@ClientType=\"Web\";\"WebAccess\";\r\n\u00a0\u00a0 \u00a0@ClientType=\"Notes\";\"NotesAccess\";\r\n\u00a0\u00a0\u00a0 \"XPiNCAccess\"\r\n)<\/pre>\n
This allows you to add specific fields to a document, or can help to identify the way how the document was created. If you add a field in the querySave<\/em> event on the XPage, you can identify if this document was created in the web by XPage or old-school web access of the form.<\/p>\n
<xp:this.data>\r\n   <xp:dominoDocument var=\"document1\" formName=\"Test\"\r\n\u00a0\u00a0    computeWithForm=\"onsave\">\r\n      <xp:this.querySaveDocument>\r\n\u00a0\u00a0 \u00a0\u00a0    <![CDATA[#{javascript:\r\n            document1.replaceItemValue(\"ClientTypeXPage\", \"1\"))\r\n         }]]>\r\n\u00a0\u00a0 \u00a0\u00a0 <\/xp:this.querySaveDocument>\r\n\u00a0\u00a0 <\/xp:dominoDocument>\r\n<\/xp:this.data><\/pre>\n
By extending the subform computation, you can use a subform for every type of access:<\/p>\n
@If(\r\n\u00a0\u00a0 \u00a0@ClientType=\"Web\" & ClientTypeXPage=\"1\";\"XPageWebAccess\";\r\n\u00a0\u00a0 \u00a0@ClientType=\"Web\";\"WebAccess\";\r\n\u00a0\u00a0 \u00a0@ClientType=\"Notes\";\"NotesAccess\";\r\n\u00a0\u00a0\u00a0 \"XPiNCAccess\"\r\n)<\/pre>\n","protected":false},"excerpt":{"rendered":"
