Is Rendered Item Valid XHtml Document Could not find schema information warnings during publish item Sitecore 7.2

Note: Since we now live in the HTML5 world, the simple resolution to any XHtml validation errors is to remove the XHtml validation rules on  System->Settings->Validation Rules->Global Rules item. Sitecore should update it's validation rules to be relevant to HTML5. This make the rest of this post obsolete :). I created a simple approval workflow in Sitecore 7.5 and tried to approve an item for publishing and found a bunch of validation errors in the Validation Results. Most of them were related to the "Is Rendered Item Valid XHtml Document" section which looked like this: The problems were related to violations of the W3C HTML5 recommendation An important note here is: The element containing the character encoding declaration must be serialized completely within the first 1024 bytes of the document.

The idea is to go from this: To: The approach is promising with a few updates: Tried implementing it by inheriting from SelectRenderingForm and it did not work. No rendering items were being listed. Had to decompile Sitecore.Client.dll and copy the code from Sitecore.Shell.Applications.Dialogs.SelectRendering.SelectRenderingForm Had to comment the following line in OnLoad  this.Renderings.InnerHtml = this.RenderPreviews((IEnumerable<Item>)renderingOptions.Items); Found a few issues with the styles, could have be an updated style sheet for Sitecore 7.5, but had to add the following attributes to the tabstrip Background="white" Padding="0px" style="position:absolute; width:100%;top:0px" Here is a detailed description of my implementati

RESOLVED: Solr Exceptions - Document contains at least one immense term in field

If you implemented Solr with Sitecore using Solr 5.x, you may run into the following error when indexing extremely large content in string fields: org.apache.solr.common.SolrException: Exception writing document id <xxxuniqueid> to the index; possible analysis error.
