    ### **Bug fixes**

    <Card title="Bug fixes" icon="bug" iconType="duotone">
      <Tabs>
        <Tab title="Customer fixes">
          Issues resolved based on customer feedback:

          <Accordion id="ZD-982" title="Task Manager View Not Updating">
            **Problem:**\
            When using a view with dataset config where assignee is set to blank, after assigning a task (or self-assigning), the view appeared unchanged. Similarly, when assignee is set to not blank and you unassign a task, the view did not update.

            **Resolution:**\
            Fixed view refresh behavior after assign/unassign operations to properly reflect the updated task state and provide visual feedback to users.
          </Accordion>

          <Accordion id="ZD-913" title="Forms in Collections - Backend Keys Calculation">
            **Problem:**\
            When saving data from outside a collection with forms to submit, the backend calculated keys for UUID entries in formsToSubmit. These keys were only partial (relative to the collection array) and could overwrite existing process values.

            **Resolution:**\
            Added a flag on PATCH /actions requests to notify the backend to exclude backend keys calculation for forms in collections UUIDs from formsToSubmit.
          </Accordion>

          <Accordion id="ZD-1002" title="Variables Reset on Config Update">
            **Problem:**\
            Updating parameters in the config page caused existing parameters to be replaced with new ones, generating new flowxUuids. This caused variables in database nodes to no longer match, losing all references.

            **Resolution:**\
            Fixed to always send id and flowxUuid for existing params when saving the operation, preserving variable references.
          </Accordion>

          <Accordion id="ZD-773" title="Build Export Timeout">
            **Problem:**\
            When exporting builds with multiple resources, some resources remained in EXPORTING status, others got EXPORT\_TIMEOUT without the build export receiving the status, and others had EXPORTED status. This was caused by Kafka messages being processed before the MongoDB transaction was committed.

            **Resolution:**\
            Fixed the export function to ensure proper sequencing of database transactions and Kafka messages during build export operations.
          </Accordion>
        </Tab>

        <Tab title="Designer fixes">
          <Accordion title="Table Row Deletable with Backspace in RUT">
            **Problem:**\
            In Reusable UI Templates, selecting a table row and pressing backspace would delete the row, even though table rows should not be deletable.

            **Resolution:**\
            Fixed keyboard handling to prevent accidental table row deletion via backspace key.
          </Accordion>
        </Tab>

        <Tab title="Renderer fixes">
          <Accordion title="Android Upload Action Payload Missing">
            **Problem:**\
            Upload action payload data (except uploadFileTempFileId) was missing on execution in the Android renderer.

            **Resolution:**\
            Fixed payload handling to include all required data in upload action execution.
          </Accordion>
