Template Processes View

[iaktern]

• Template Editor writes into a new "TemplateProcess" table, same columns as in Process table (a new table is faster for search and managing instead of a new column in the Process table)
• add a column "basedOnTemplateId" and "basedOnTemplateVersion" in "Process" AND "TemplateProcess" tables referring to the id of the Template
• add column "templateProcessId" in Version table and link the "TemplateProcess" table
• Create View for Templates (normal list/icon view like in the Editor view)
• Change "Create Process" modal: 1. add a string prop for the component that the modal uses to show what is created in the text title and input labels, e.g. "Create Process" or "Create Template". Default: "Process". 2. use this modal for creating Templates (prop = "Template") 3. Add an input field where you can select a Template which the new Process/Template is based on (yes, also Templates can be based on other Templates). Only Templates should be selectable, which have a defined Version
• Add fields in the BPMN editors property panel about the "Based on Template: " (show Name not Id) and "Based on Template Version:"
• add in the BPMN XML inside the definitions element as attributes: proceed:basedOnTemplateId="_5t...a4ht3" proceed:basedOnTemplateVersionId="_df89...ht43"
• check if everything else works like for the normal process editor

From Lucas- TODOs:

• Currently, the handling of templates and processes in the DB is not ideal, because for the requested process/template both DB tables are searched through until the requested process/template is found. It should be implemented a mechanism to known in which table to search for the requested resource.
• Import of Templates is not implemented
• Currently, Templates can be used even without a published version. This should be changed to only allow to use versioned templates
• Refactoring
