Dear sharepoint developers, I am facing a weird issue when updating an item in a custom list. One filed I have in a list is of type HTML; I have some CSS classes associated with java script that read certain HTML tags and produce a tool tip by a mouse over; the structure of this HTML script is XML-wise as follows: <snippet> <a href="#" class="tt"> keyword<div class="ttcontainer"> <span class="tooltip"> <span class="bottom"> <span class="middle">definition</span> <span class="top"></span> </span> </span> </div> </a> </snippet> My List Item; let's call it 'item' gets updated in a similar way as follows: <snippet> item["field_name"] = "<a href=\"#\" class=\"tt\">keyword<div class= \"ttcontainer\"><span class=\"tooltip\"><span class=\"bottom\"><span class=\"middle\">definition</span><span class=\"top\"></span></span></ span></div></a>"; </snippet> During debug time and before updating, I trace the value and it's as expected, I confirm that the saved value inside the item["field_name"] matches exactly the one above; however, after updating: <snippet> item.Update(); </snippet> The value gets changed automatically from sharepoint; my HTML code above misses two span closing tags and the surrounding double quotes of the classes are missing as well as follows: <snippet> <a href="#" class=tt> keyword<div class=ttcontainer> <span class=tooltip> <span class=bottom> <span class=middle>definition</span> <span class=top></span> </div> </a> </snippet> Concerning the surrounding double quotes, it's not that bad, I can live without them! but the missing span closing tags! offfff ..., I had some rough time figuring out how it happens and I had been reviewing my code for weeks doubting my logic and finally it seemed that sharepoint changes it from its own! Any idea on how to fix this? Is this a bug? do I need to pay extra attention when dealing with fields of HTML type? I'm puzzled! Regards
