I am currently working on a huge application which exists for many years now, and has a long history with different developers and just a few manuals and\/or documentations. But as often it is a critical business application which is in use across different countries 24\/7. The more danger, the more<\/del> less honor: Every fault is just a further nail in the coffin of the developer…<\/p>\n

Today I had to develop an extension for this application, and this has driven me crazy, because it was a pain to identify to problem: After creating a document from a XPage the workflow stopped. When filling out the form in in the NotesClient the problem did not occur. But using the same form in a XPage (with computeWithForm<\/em>) did not work.<\/p>\n

After investigating I found out that the problem was caused by a required field which was not created. It was just not there, nothing, nada.<\/p>\n

In the form it was defined as a computed field…<\/p>\n

\"\"<\/p>\n

… but even with a simple XPage …<\/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\u00a0\u00a0 \u00a0<xp:this.data>\r\n\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0<xp:dominoDocument var=\"document1\" formName=\"Doc\"\r\n\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0computeWithForm=\"onsave\">\r\n\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0<\/xp:dominoDocument>\r\n\u00a0\u00a0 \u00a0<\/xp:this.data>\r\n\r\n\u00a0\u00a0 \u00a0<xp:button value=\"Save\" id=\"buttonSubmit\">\r\n\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0<xp:eventHandler event=\"onclick\" submit=\"true\"\r\n\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0refreshMode=\"complete\" immediate=\"false\" save=\"true\" \/>\r\n\u00a0\u00a0 \u00a0<\/xp:button>\r\n\u00a0\u00a0 \u00a0<xp:br \/>\r\n\u00a0\u00a0 \u00a0<xp:messages id=\"errMessages\" \/>\r\n\r\n<\/xp:view><\/code><\/pre>\n
… the field was not created:<\/p>\n
\"\"<\/p>\n
[I have tried the computeWithForm parameter with every available option.]<\/em><\/p>\n
Searching for a quick workaround I tried to use an oldschool LS agent, but even then the mystery was not solved. Instead, it grew:<\/p>\n

This was the resulting error message:<\/p>\n
\"\"<\/p>\n
When opening the form in the NotesClient and saving the document, everything works as expected:<\/p>\n
\"\"<\/p>\n
What’s going on here? It was really interesting to find the reason. In the last years I always thought that computed fields have always values defined in the form. But this is not a requirement for author fields:<\/p>\n
\"\"<\/p>\n
Adding a simple @UserName<\/em> to the field, and the issue was solved.<\/p>\n","protected":false},"excerpt":{"rendered":"
