====Frequent errors=====

Various errors can occur while creating a smartform, which prevent that a [[deploy_processdefinition| process definition is deployable]]. Indeed, if the smartform is erroneous, either an error occurs already at deployment and fails, or the smartform is not visible in the client.

===Sources of errors===

  * the syntax of the smartform is incorrect. This can be checked with the following [[http://validator.w3.org/|validator]]. This should display no errors anymore so the syntax can be excluded as a source of error.
  * The same ID was used for multiple elements. Thus, the alocation of the [[en:software:tim:process_variables#Prozessvariablen | process variable]] is no longer correct and the right fields can not be filled with the appropriate information.
  * if the [[smartform_basics#javascript_einbinden | custom.js]] is not loaded, errors are located in the syntax and prevent the smooth functioning.
