Modeler Release 5.1

Available since March 18, 2026

This Modeler Release is only for Modeler - Runtimes are not affected. The fact remains that using new features or new expressions may cause issues when they are used in runtimes that do not support the specific feature. In most cases the Runtime should show a friendly informative message about non-supported feature, but in some cases it may display a technical error. This is definitely the case in Preview...

WARNING: if new features are used in Preview, hard crashes can happen.

Use Conditional blocks or nodes and the IsPreview() function to exclude new features from being accessed in Preview.

The NEW Preview on Kubernetes will become available soon and that will be the solution going forward for all new features.

New features

• The function IsDirty() has been added. This returns true if a database row or field has a value that has not been saved to the database yet. In other words, there is a value that will be written to the database if a "Save changes" node is invoked. Note that this value could be the exact value that is already stored in the database.

• The function GetFlowchartID() and GetFlowchartName() have been added. They return the ID or name of the current flowchart.

• The function GetNodeName() has been added. This function returns the name of the current node.

• The function Sha512(text) has been added. This is similar to the Sha256(text) function.

• Limit source to parent flag for loop node, goto row list node, and data export node. This flag applies to nodes that work on nested lists and is enabled by default. The default behavior in WEM is that the parent row position is taken when working with lists. If the flag is switched off, all rows of the nested list considered in the operation. Switching off this flag is similar to the all keyword in WEM script.

• Skip and Take for data export nodes (for JSON and XML find them in Mappings on array objects).

• WEM Script keyword order by added.

• Combo-box presentation for select-input based on Lists (reference fields) - to combine auto-completion / filter options on the list-item-selector.
