This behavior appears if the following operations are done.
1)Display Workspace page or Commonspace page on embedded browser in Creo Parametric.
2)Search only one CAD object with only CAD Document type of the search UI . (This issue doesn’t occur if selecting All types.)
2)If only one CAD object is searched, the information page of the searched CAD object is loaded automatically instead of the Workspace or the Commonspace.
According to CS257858 and CS264332(this is helpful to understand this issue although it is written for other issue), it seems that it works to product specification for Windchill PDMLink 11.0.
However customers don’t hope such a function. Please don’t load the information page even if there is only one result in search result table.
