This problem doesn't happen if i load the schema to tSetDynamicSchema from a delimited file instead. Below the job and the wrong results.</P><P>Is it a bug or am i doing something wrong?<BR /><BR /></P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="vintac_1-1761645193452.png" style="width: 400px;"><img src="https://community.qlik.com/t5/image/serverpage/image-id/184510iB32CE9140D9E485A/image-size/medium?v=v2&amp;px=400" role="button" title="vintac_1-1761645193452.png" alt="vintac_1-1761645193452.png" /></span></P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="vintac_0-1761645168284.png" style="width: 400px;"><img src="https://community.qlik.com/t5/image/serverpage/image-id/184509i2FB24C2375286C0A/image-size/medium?v=v2&amp;px=400" role="button" title="vintac_0-1761645168284.png" alt="vintac_0-1761645168284.png" /></span></P><P>&nbsp;</P><P>Regards,</P><P>Vincenzo.</P><P>&nbsp;</P> Tue, 28 Oct 2025 09:54:49 GMT https://community.qlik.com/t5/Talend-Studio/Problem-with-tSetDynamicSchema/m-p/2534553#M148132 vintac 2025-10-28T09:54:49Z https://community.qlik.com/t5/Talend-Studio/Problem-with-tSetDynamicSchema/m-p/2534561#M148133 <P>ok, i think i found the problem, when i use the same tSetDynamicSchema first reading schema from a file and then reading from other component, for any reason the <EM>read schema from file</EM> option remains hiddenly selected even after the connection with the other component, and this is causing the erroneous behaviour: practically it's reading the schema from several sources at same time.</P><P>If you first deselect the <EM>read schema from file</EM> option and then connect with other source component, the results are correct.
